terraform variables may not be used here. I just finished deploying a 3 stage app, and ended up using workspaces which didn't feel right. Another use case that should be considered is to use a data source for configuring a backend. Is that intended behavior? Looking at my ‘terraform.tfvars’ file I declare specific variables that are applied to my deployment. This is covered pretty well in the Hashicorp Docs here (single page read <5 minutes) and if you have a LinkedIn Learning account check out my Terraform course “Learning Terraform“.. seems variable are not allowed in that block Already on GitHub? @umeat in that case you are right, it is not possible at the moment to use different backends for each environment. Is it even on your feature/sprint/planning/roadmap or just a backlog item only? Revert attempt to parametrize allowing destruction of hub disk. Reply to this email directly, view it on GitHub By deploying lightweight agents within a specific network segment, you can establish a simple connection between your environment and Terraform Cloud which allows for provisioning operations and management. The same of: #3116 If it works for you then "it is" the best solution. storage access key and the MSI approach is not going to work considering Reference: Variables may not be used here. We’ll occasionally send you account related emails. Ideally I'd want my structure to look like "project/${var.git_branch}/terraform.tfstate", yielding: Now, everything you find for a given project is under its directory... so long as the env is hard-coded at the beginning of the remote tfstate path, you lose this flexibility. Variables may not be used here. Can you close, please? Initializing the backend... on provider.tf line 8, in terraform: They push environment management complexity into separate docker images (ex. Even when you don't create a module intentionally, if you use Terraform, you are already writing a module – a so-called "root" module. e.g. I found that Terraform is like perl (does anyone still use perl?) resource_group_name = var.statefile_storage_account_rg AWS RDS has a deletion_protection option that is easy to set. Environment-or-case-specific *.tfvars files with all variable values which will be specific to a particular case or environment, and will be explicitly used when running terraform plan command. to your account. }. Can someone with the inner knowledge of this "feature" work please step up and give us some definitive answers on simple things like: Thanks for your work - Hashicorp - this tool is awesome! Perhaps a middle ground would be to not error out on interpolation when the variable was declared in the environment as TF_VAR_foo? secret_key = "${var.aws_secret_key}" In this first release along the lines of these new capabilities, we’ve focused on input variables & module outputs first, with an additional opt-in experiment for values which provider schemas mark as sensitive. Successfully merging a pull request may close this issue. } 8: resource_group_name = var.statefile_storage_account_rg, on provider.tf line 9, in terraform: Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists... to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). You are receiving this because you are subscribed to this thread. variables.tf. bucket = "ops" We don't want the devs to see the at the expense of developer convenience when cloning the repo and having to Feature request. Complete Step 1 and Step 2 of the How To Use Terraform with DigitalOcean tutorial, and be sure to name the project folder terraform-flexibility, instead of loadbalance. Here is an example of code I used in my previous article: My knowledge is really limited of terraform and have gotten through most bits that I have needed but this i am stuck on. The values can be found in the environment specific .tfvars files. It's over 4 years since #3116 was opened, I think we'd all appreciate some indication of where this is? privacy statement. oh well since after these years this issue is still open i think i will drop the issue i experience on here. This is one of the best threads ever. issue is not helping. As an example of the file structure of this approach, this is what the project we’ll build in … 11: key = var.statefile_name, seems variable are not allowed in that block. Off the top of my head I can think of the following limitations: All of these make writing enterprise-level Terraform code difficult and more dangerous. Not slanting at you, just frustrated that this feature is languishing and I NEED it ... Now.... @Penumbra69 and all the folks on here: I hear you, and the use cases you're describing totally make sense to me. Hello Everyone, Welcome to devopsstack, If you observe our previous… Continue Reading Terraform variables. It's not pretty but it works, and is hidden away in the module for the most part: Module originated prior to 0.12, so those conditionals could well be shortened using bool now. The TF engine is not yet running when the values are assigned. In Terraform 0.10 there will be a new setting workspace_key_prefix on the AWS provider to customize the prefix used for separate environments (now called "workspaces"), overriding this env: convention. Switching which infrastructure you're operating against could be as easy as checking out a different git branch. I wanted to extract these to variables because i'm using the same values in a few places, including in the provider config where they work fine. Prerequisites before all of this. container_name = var.statefile_container Have a question about this project? Variable defaults / declarations cannot use conditionals. My use case is very much like @weldrake13's. All files in your Terraform directory using the .tf file format will be automatically loaded during operations. E.g. As a workaround, since we use the S3 backend for managing our Terraform workspaces, I block the access to the Terraform workspace S3 bucket for the Terraform IAM user in my shell script after Terraform has finished creating the prod resources. storage_account_name = var.statefile_storage_account Microservices are better versioned and managed discretely per component, rather than dumped into common prod/staging/dev categories which might be less applicable on a per-microservice basis, each one might have a different workflow with different numbers of staging phases leading to production release. This use case is pretty straight forward, you can just set the environment variables once and everything will be able to connect. Also I appreciate this is one resource duplicated, and it would be much worse elsewhere for larger configurations. And it works.. Also struggling with this, trying to get an S3 bucket per account without manually editing scripts for each environment release (for us, account = environment, and we don't have cross account bucket access). This value can then be used to pass variables to modules based on the currently configured workspace. ... You may now begin working with Terraform. ‍♂️. S3 Buckets have an mfa_delete option which is difficult to enable. In the mean time, although not ideal, a light wrapper script using cli vars works well. privacy statement. I think this would be even harder to do since the state stores some information regarding what provider is used by which resource. I have created a sample GitHub repo that holds the code examples we are going to look at below. In the video I change the capacity of the virtual machine scale set from 5 to 25. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. could have replaced it via our key vault secrets as we do the others but The way I'm handling this is defining the backend without the "key" parameter. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. <, Using variables in terraform backend config block. the securing of the state file's storage account would have been a lot Terraform installed on your local machine and a project set up with the DigitalOcean provider. You signed in with another tab or window. so while I'm bummed that this doesn't work, I understand that I shouldn't expect it to. We have started to see Terraform as being difficult to secure and this issue is not helping. We have a project that is being developed by a 3rd party and getting deployed in Azure. Same thing for me. We issue dev environments to each dev, and so our backend config would look like. Terraform is not mature yet But I get this error for terraform init >>> I have the same problem i.e. in backend config, but its simple. The reason this works is due to Terraform variable values (and providers) do not support interpolation. For example, the AWS Terraform provider allows you to automatically source local environment variables, which solves the issue of placing secrets in places they should be, ie. In case it's helpful to anyone, the way I get around this is as follows: All of the relevant variables are exported at the deployment pipeline level for me, so it's easy to init with the correct information for each environment. In my use case i need to reuse the same piece of code (without writing a new repo each time i'd want to consume it as a module) to maintain multiple separate statefiles. Trying to run terraform block with variables like so, terraform { I managed to get it working by using AWS profiles instead of the access keys directly. Tedious, but it works. Is the reason for this limitation security? It would be an infrastructure-as-code dream to get this working. The word "backend" can not be found on page https://www.terraform.io/docs/configuration/variables.html. Example here is a module for gcloud sql instance, where obviously in production I want to protect it, but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. Deploying the HA AKS cluster. Variables may not be used here. variables/prod.tfvars; main.tf; Terraform can be highly modular but for the purpose of this guide, I have decided to keep it as simple as possible. It would be more comfortable to have a backend mapping for all environments what is not implemented yet. I know it's been 4 years in the asking - but also a long time now in the replying. By clicking “Sign up for GitHub”, you agree to our terms of service and However, we discovered this behavior because running terraform init failed where it had once worked. We can use the resources to then describe what features we want enabled, disabled, or configured. It is so funny. 1 terraform apply # Without a planfile, supply Terraform variables here Because Terragrunt automates so much, it becomes import to make sure application configuration protects against running into Terraform’s quirks: otherwise, it’s easy to inadvertently pass variables to an apply with a planfile and everything will explode . In my example you could still use terraform environments to prefix the state file object name, but you get to specify different buckets for the backend. Seen multiple threads like this. Disappointing to see that so many messy (IMO) workarounds are still being used because Terraform still can't handle this. I felt there should be a higher level abstraction of each environment such as a folder (terragrunt) or docker image (cloudposse). At the moment we use multiple environments prod/stage and want to upload tfstate files to S3. VPC endpoints - Instead of accessing ECR images through NAT from ECS, we could define VPC Endpoints for ECR, S3 and CloudWatch. no..it has been 3 years and no answer. variables.tf is the home of all the variables but not the values themselves. *} inside backend configuration, terraform.backend: configuration cannot contain interpolations. I've knocked up a bash script which will update TF_VAR_git_branch every time a new command is run from an interactive bash session. The end user's backend is not of concern to our terraform configuration. encrypt = "true" Please note: I do not use real code examples with some specific provider like AWS or Google intentionally, just for the sake of simplicity. provider "aws" { - region = "us-west-2" + region = var.region } This uses the variable named region, prefixed with var.. Instead we now have to do a nasty workaround by tokenizing that access key writing the keys into configurations or state. Already on GitHub? It would be nice to understand why this can't work. Thought I'd offer up a work around I've used in some small cases. Terraform modules You already write modules. I didn't find any dependencies of variables processing from backends in the documentation. party and getting deployed in Azure. I really like CloudPosse's solution to this problem. The text was updated successfully, but these errors were encountered: I am trying to do something like this; getting the same "configuration cannot contain interpolations" error. Extract the binary to a folder. -backend-type=s3 , -backend-type=kubernetes , etc.. dev.acme.com, staging.acme.com, prod.acme.com) and modify the backend variables in each environments Dockerfile. Almost 4 years in the making and still not fix to this? Extract the binary to a folder. I am on the most current version of Terraform. Instead I have to use the role_arn in the backend config which can't contain the interpolation I need. Have a basic understanding of how to use Terraform and what it does. You signed in with another tab or window. It configures the AWS provider with the given variable. This effectively locks down the infrastructure in the workspace and requires a IAM policy change to re-enable it. We’re excited to announce that Terraform 0.14 includes the ability to thread the notion of a “sensitive value” throughout Terraform. Add the folder to the path environment variable so that you can execute it from anywhere on the command line. I would also appreciate if Terraform allows variables for specifying "prevent_destroy" values. If this gets closed then those following cant view the issue. There is an ongoing issue (#3116) which is currently open but @teamterraform seem to have made that private to contributors only. Though this might require making such variables immutable? Once the change is applied, Azure is quick to deploy these (remember, this all depends on datacentre capacity). Commenting on #3119 was locked almost 2 years ago saying "We'll open it again when we are working on this". Here is the error Output of terraform validate: I needs dis! Terraform will split and store environment state files in a path like this: @NickMetz it's trying to do multiple environments with multiple backend buckets, not a single backend. Terraform does not yet have native support for decrypting files in the format used by sops.One solution is to install and use the custom provider for sops, terraform-provider-sops.Another option, which I’ll demonstrate here, is to use Terragrunt, which has native sops support built in. This way we could keep all the traffic on the private network. Instead we now have to do a nasty workaround by tokenizing that access key at the expense of developer convenience when cloning the repo and having to manually change the token file, So, we are looking at switching to Pulumi as they seem to understand this concept. terraform apply -var region=”eu-west-1” I write tests for my modules. Since key is a required parameter, terraform prompts me for it. It would be create if we can use variables in the lifecycle block because without using variables I'm literally unable to use prevent_destroy in combination with a "Destroy-Time Provisioner" in a module. We want collaboration between the 3rd party's devs and our guys easy so This is particularly useful if HashiCorp Vault is being used for generating access and secret keys. Terraform users describe these configurations -- for networking, domain name routing, CPU allotment and other components -- in resources, using the tool's configuration language.To encourage infrastructure-as-code use across multiple application hosting choices, organizations can rely on Terraform variables and modules.Variables are independent of modules and can be used in any Terraform … That way we We want collaboration between the 3rd party's devs and our guys easy so the securing of the state file's storage account would have been a lot easier if it was just allowed to be replaced by a variable. would love to see interpolations in the backend config. Nobody here is wrong. » Configuring Terraform Cloud Variables for HCS on Azure We need to configure a few variables that will tell Terraform Cloud how it can interact with HCS on Azure. Terraform doesn't allow you to interpolate variables within the variables file otherwise you get the error: Error: Variables not allowed. aws-vault, k8s etc.). } Sign in Perhaps it's better to just give accross account access to the user / role which is being used to deploy your terraform. It tells Terraform that you're accessing a variable and that the value of the region variable should be used here. this works fine if i dont use variables. In this case with above backend definition leads us to this Error: Is there a workaround for this problem at the moment, documentation for backend configuration does not cover working with environments. on provider.tf line 11, in terraform: 11: key = var.statefile_name. I also would like to be able to use interpolation in my backend config, using v 0.9.4, confirming this frustrating point still exists. It would be helpful if it were possible to decouple it completely. Other kinds of variables in Terraform include environment variables (set by the shell where Terraform runs) and expression variables (used to indirectly represent a value in an expression ). https://github.com/cloudposse/dev.cloudposse.co Error: Variables not allowed. And will it, if I do this workaround, keep working? So, we are looking at switching to Pulumi as they seem to understand this In Part 2, we introduced the basic syntax and features of Terraform and used them to deploy a cluster of web servers on AWS. Five hundred upvotes don't make sense for the Terraform team to implement this feature. You can also define the values in the variables file. I'm hitting this, too. Successfully merging a pull request may close this issue. Of course, this is just an example which may or not … Seem like you need CI instead of granting devs access to your state, On Tue, 22 Sep 2020, 13:35 KatteKwaad, ***@***. Just ran into this but with a "normal" variable. One of the first steps on the pipeline does: From this point, the runners understands that the 00-backend.tf contains a valid Terraform Backend configuration. key = var.statefile_name "Variables may not be used here" for `prevent_destroy`, ministryofjustice/cloud-platform-terraform-rds-instance#48. You could store the keys in Azure Key Vault, then get it using data provider and use that value for the storage access instead of hardcoded value. I dont know if you tested using Data in the backend block and it worked. Thus the engine is running and interpolation is supported. Terraform Cloud Agents allow Terraform Cloud to communicate with isolated, private, or on-premises infrastructure. concept Hashicorp locked down 3116. We have started to see Terraform as being difficult to secure and this It would be nice if we were able to pass in variables to make the key interchangeable with say a tfvars variable. Better Terraform variable usage - We could map multiple subnet AZ to single variable and use Terraform's functions to map those values. Same issue, trying to create S3 and Dynamo resources for, and deploy another project infrastructure in one flow. The first method we will look at is to use an input variable at the command line this is the simplest of methods and most commonly used for ad-hoc overrides, here we simply add a -var ‘variable_name=”value” as an option for the terraform plan or apply command. It's documented at TF_CLI_ARGS and TF_CLI_ARGS_name. It tells Terraform that you're accessing a variable and that the value of the region variable should be used here. region = "us-east-1" I need to be able to re-run tests over and over. Have a question about this project? https://github.com/cloudposse/prod.cloudposse.co, So we're not granting them access to state as we're tokenizing the value out and securing it in KeyVault but the functionality to handle the process as a first class citizen is what is missing. set lifecycle to prevent destroying anything marked as production. }. I don't find this ideal, but at least I can easily switch between environments and create new environments without having to edit any terraform. Any planned changes? Terraform variables. We’ll occasionally send you account related emails. The Terraform Azure DevOps Provider allows us to be able to create a standard Terraform deployment that creates a Project inside a DevOps Organization. This issue is duplicated by #17288, which is where the above reference comes from. outputs on the other hand are evaluated near the end of a TF life cycle. Try running "terraform plan" to see. The text was updated successfully, but these errors were encountered: prevent_destroy cannot support references like that, so if you are not seeing an error then the bug is that the error isn't being shown; the reference will still not be evaluated. Hi, I don’t represent the hashi team but following this thread and others for awhile I don’t believe there’s any disagreement in its benefit, terraform team is slowing working its way towards it (hcl2 consuming a large part of those 3 years and now working on better support for modules). There are multiple ways to assign variables. And they can contain default values in case no values are submitted during runtime. manually change the token file And indeed, if you comment out the variable reference in the snippet above, and replace it with prevent_destroy = false, it works - and if you then change it back it keeps working. @KatteKwaad What's the problem to process script variables before processing the backend config? I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. backend "azurerm" { Terraform supports multiple different variables types. to your account, Variables are used to configure the backend. Note: For brevity, input variables are often referred to as just "variables" or "Terraform variables" when it is clear from context what sort of variable is being discussed. terraform variables may not be used here. Your top-level structure looks nice and tidy for traditional dev/staging/prod ... sure: But what if you want to stand up a whole environment for project-specific features being developed in parallel? terraform-compliance is providing a similar functionality only for terraform while it is free-to-use and it is Open Source. ", I believe we can close this given the solution provided at #20428 (comment). I'm recategorizing this as an enhancement request because although it doesn't work the way you want it to, this is a known limitation rather than an accidental bug. ***> wrote: What I did though was not optimal; but in my build steps, I ran a bash script that called AWS configure that ultimately set the default access key and secret. I know a +1 does not add much but yeah, need this too to have 2 different buckets, since we have 2 AWS accounts. Terraform variables can be defined within the infrastructure plan but are recommended to be stored in their own variables file. Full control over the paths is ideal, and we can only get that through interpolation. Some things work in Terraform version 0.11 that do not work in version 0.12. trying to create 3x routes into different route tables, each the same route. Now that we have "environments" in terraform, I was hoping to have a single config.tf with the backend configuration and use environments for my states. Deployment is 100% automated for us, and if the dev teams need to make a change to a resource, or remove it then that change would have gone through appropriate testing and peer review before being checked into master and deployed. Sign in Wrapper/Terragrunt seems to be the 2020 solution when you're deploying many modules to different environments. Code changes needed for version 12.

I just finished deploying a 3 stage app, and ended up using workspaces which didn't feel right. Another use case that should be considered is to use a data source for configuring a backend. Is that intended behavior? Looking at my ‘terraform.tfvars’ file I declare specific variables that are applied to my deployment.

Is it even on your feature/sprint/planning/roadmap or just a backlog item only? Revert attempt to parametrize allowing destruction of hub disk. Reply to this email directly, view it on GitHub By deploying lightweight agents within a specific network segment, you can establish a simple connection between your environment and Terraform Cloud which allows for provisioning operations and management. The same of: #3116 If it works for you then "it is" the best solution. storage access key and the MSI approach is not going to work considering Reference: Variables may not be used here. We’ll occasionally send you account related emails. Ideally I'd want my structure to look like "project/${var.git_branch}/terraform.tfstate", yielding: Now, everything you find for a given project is under its directory... so long as the env is hard-coded at the beginning of the remote tfstate path, you lose this flexibility. Variables may not be used here. Can you close, please? Initializing the backend... on provider.tf line 8, in terraform: They push environment management complexity into separate docker images (ex. Even when you don't create a module intentionally, if you use Terraform, you are already writing a module – a so-called "root" module. e.g. I found that Terraform is like perl (does anyone still use perl?) resource_group_name = var.statefile_storage_account_rg AWS RDS has a deletion_protection option that is easy to set. Environment-or-case-specific *.tfvars files with all variable values which will be specific to a particular case or environment, and will be explicitly used when running terraform plan command. to your account. }. Can someone with the inner knowledge of this "feature" work please step up and give us some definitive answers on simple things like: Thanks for your work - Hashicorp - this tool is awesome! Perhaps a middle ground would be to not error out on interpolation when the variable was declared in the environment as TF_VAR_foo? secret_key = "${var.aws_secret_key}" In this first release along the lines of these new capabilities, we’ve focused on input variables & module outputs first, with an additional opt-in experiment for values which provider schemas mark as sensitive. Successfully merging a pull request may close this issue. } 8: resource_group_name = var.statefile_storage_account_rg, on provider.tf line 9, in terraform: Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists... to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). You are receiving this because you are subscribed to this thread. variables.tf. bucket = "ops" We don't want the devs to see the at the expense of developer convenience when cloning the repo and having to Feature request. Complete Step 1 and Step 2 of the How To Use Terraform with DigitalOcean tutorial, and be sure to name the project folder terraform-flexibility, instead of loadbalance. Here is an example of code I used in my previous article: My knowledge is really limited of terraform and have gotten through most bits that I have needed but this i am stuck on. The values can be found in the environment specific .tfvars files. It's over 4 years since #3116 was opened, I think we'd all appreciate some indication of where this is? privacy statement. oh well since after these years this issue is still open i think i will drop the issue i experience on here. This is one of the best threads ever. issue is not helping. As an example of the file structure of this approach, this is what the project we’ll build in … 11: key = var.statefile_name, seems variable are not allowed in that block. Off the top of my head I can think of the following limitations: All of these make writing enterprise-level Terraform code difficult and more dangerous. Not slanting at you, just frustrated that this feature is languishing and I NEED it ... Now.... @Penumbra69 and all the folks on here: I hear you, and the use cases you're describing totally make sense to me. Hello Everyone, Welcome to devopsstack, If you observe our previous… Continue Reading Terraform variables. It's not pretty but it works, and is hidden away in the module for the most part: Module originated prior to 0.12, so those conditionals could well be shortened using bool now. The TF engine is not yet running when the values are assigned. In Terraform 0.10 there will be a new setting workspace_key_prefix on the AWS provider to customize the prefix used for separate environments (now called "workspaces"), overriding this env: convention. Switching which infrastructure you're operating against could be as easy as checking out a different git branch. I wanted to extract these to variables because i'm using the same values in a few places, including in the provider config where they work fine. Prerequisites before all of this. container_name = var.statefile_container Have a question about this project? Variable defaults / declarations cannot use conditionals. My use case is very much like @weldrake13's. All files in your Terraform directory using the .tf file format will be automatically loaded during operations. E.g. As a workaround, since we use the S3 backend for managing our Terraform workspaces, I block the access to the Terraform workspace S3 bucket for the Terraform IAM user in my shell script after Terraform has finished creating the prod resources. storage_account_name = var.statefile_storage_account Microservices are better versioned and managed discretely per component, rather than dumped into common prod/staging/dev categories which might be less applicable on a per-microservice basis, each one might have a different workflow with different numbers of staging phases leading to production release. This use case is pretty straight forward, you can just set the environment variables once and everything will be able to connect. Also I appreciate this is one resource duplicated, and it would be much worse elsewhere for larger configurations. And it works.. Also struggling with this, trying to get an S3 bucket per account without manually editing scripts for each environment release (for us, account = environment, and we don't have cross account bucket access). This value can then be used to pass variables to modules based on the currently configured workspace. ... You may now begin working with Terraform. ‍♂️. S3 Buckets have an mfa_delete option which is difficult to enable. In the mean time, although not ideal, a light wrapper script using cli vars works well. privacy statement. I think this would be even harder to do since the state stores some information regarding what provider is used by which resource. I have created a sample GitHub repo that holds the code examples we are going to look at below. In the video I change the capacity of the virtual machine scale set from 5 to 25. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. could have replaced it via our key vault secrets as we do the others but The way I'm handling this is defining the backend without the "key" parameter. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. <, Using variables in terraform backend config block. the securing of the state file's storage account would have been a lot Terraform installed on your local machine and a project set up with the DigitalOcean provider. You signed in with another tab or window. so while I'm bummed that this doesn't work, I understand that I shouldn't expect it to. We have started to see Terraform as being difficult to secure and this issue is not helping. We have a project that is being developed by a 3rd party and getting deployed in Azure. Same thing for me. We issue dev environments to each dev, and so our backend config would look like. Terraform is not mature yet But I get this error for terraform init >>> I have the same problem i.e. in backend config, but its simple. The reason this works is due to Terraform variable values (and providers) do not support interpolation. For example, the AWS Terraform provider allows you to automatically source local environment variables, which solves the issue of placing secrets in places they should be, ie. In case it's helpful to anyone, the way I get around this is as follows: All of the relevant variables are exported at the deployment pipeline level for me, so it's easy to init with the correct information for each environment. In my use case i need to reuse the same piece of code (without writing a new repo each time i'd want to consume it as a module) to maintain multiple separate statefiles. Trying to run terraform block with variables like so, terraform { I managed to get it working by using AWS profiles instead of the access keys directly. Tedious, but it works. Is the reason for this limitation security? It would be an infrastructure-as-code dream to get this working. The word "backend" can not be found on page https://www.terraform.io/docs/configuration/variables.html. Example here is a module for gcloud sql instance, where obviously in production I want to protect it, but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. Deploying the HA AKS cluster. Variables may not be used here. variables/prod.tfvars; main.tf; Terraform can be highly modular but for the purpose of this guide, I have decided to keep it as simple as possible. It would be more comfortable to have a backend mapping for all environments what is not implemented yet. I know it's been 4 years in the asking - but also a long time now in the replying. By clicking “Sign up for GitHub”, you agree to our terms of service and However, we discovered this behavior because running terraform init failed where it had once worked. We can use the resources to then describe what features we want enabled, disabled, or configured. It is so funny. 1 terraform apply # Without a planfile, supply Terraform variables here Because Terragrunt automates so much, it becomes import to make sure application configuration protects against running into Terraform’s quirks: otherwise, it’s easy to inadvertently pass variables to an apply with a planfile and everything will explode . In my example you could still use terraform environments to prefix the state file object name, but you get to specify different buckets for the backend. Seen multiple threads like this. Disappointing to see that so many messy (IMO) workarounds are still being used because Terraform still can't handle this. I felt there should be a higher level abstraction of each environment such as a folder (terragrunt) or docker image (cloudposse). At the moment we use multiple environments prod/stage and want to upload tfstate files to S3. VPC endpoints - Instead of accessing ECR images through NAT from ECS, we could define VPC Endpoints for ECR, S3 and CloudWatch. no..it has been 3 years and no answer. variables.tf is the home of all the variables but not the values themselves. *} inside backend configuration, terraform.backend: configuration cannot contain interpolations. I've knocked up a bash script which will update TF_VAR_git_branch every time a new command is run from an interactive bash session. The end user's backend is not of concern to our terraform configuration. encrypt = "true" Please note: I do not use real code examples with some specific provider like AWS or Google intentionally, just for the sake of simplicity. provider "aws" { - region = "us-west-2" + region = var.region } This uses the variable named region, prefixed with var.. Instead we now have to do a nasty workaround by tokenizing that access key writing the keys into configurations or state. Already on GitHub? It would be nice to understand why this can't work. Thought I'd offer up a work around I've used in some small cases. Terraform modules You already write modules. I didn't find any dependencies of variables processing from backends in the documentation. party and getting deployed in Azure. I really like CloudPosse's solution to this problem. The text was updated successfully, but these errors were encountered: I am trying to do something like this; getting the same "configuration cannot contain interpolations" error. Extract the binary to a folder. -backend-type=s3 , -backend-type=kubernetes , etc.. dev.acme.com, staging.acme.com, prod.acme.com) and modify the backend variables in each environments Dockerfile. Almost 4 years in the making and still not fix to this? Extract the binary to a folder. I am on the most current version of Terraform. Instead I have to use the role_arn in the backend config which can't contain the interpolation I need. Have a basic understanding of how to use Terraform and what it does. You signed in with another tab or window. It configures the AWS provider with the given variable. This effectively locks down the infrastructure in the workspace and requires a IAM policy change to re-enable it. We’re excited to announce that Terraform 0.14 includes the ability to thread the notion of a “sensitive value” throughout Terraform. Add the folder to the path environment variable so that you can execute it from anywhere on the command line. I would also appreciate if Terraform allows variables for specifying "prevent_destroy" values. If this gets closed then those following cant view the issue. There is an ongoing issue (#3116) which is currently open but @teamterraform seem to have made that private to contributors only. Though this might require making such variables immutable? Once the change is applied, Azure is quick to deploy these (remember, this all depends on datacentre capacity). Commenting on #3119 was locked almost 2 years ago saying "We'll open it again when we are working on this". Here is the error Output of terraform validate: I needs dis! Terraform will split and store environment state files in a path like this: @NickMetz it's trying to do multiple environments with multiple backend buckets, not a single backend. Terraform does not yet have native support for decrypting files in the format used by sops.One solution is to install and use the custom provider for sops, terraform-provider-sops.Another option, which I’ll demonstrate here, is to use Terragrunt, which has native sops support built in. This way we could keep all the traffic on the private network. Instead we now have to do a nasty workaround by tokenizing that access key at the expense of developer convenience when cloning the repo and having to manually change the token file, So, we are looking at switching to Pulumi as they seem to understand this concept. terraform apply -var region=”eu-west-1” I write tests for my modules. Since key is a required parameter, terraform prompts me for it. It would be create if we can use variables in the lifecycle block because without using variables I'm literally unable to use prevent_destroy in combination with a "Destroy-Time Provisioner" in a module. We want collaboration between the 3rd party's devs and our guys easy so This is particularly useful if HashiCorp Vault is being used for generating access and secret keys. Terraform users describe these configurations -- for networking, domain name routing, CPU allotment and other components -- in resources, using the tool's configuration language.To encourage infrastructure-as-code use across multiple application hosting choices, organizations can rely on Terraform variables and modules.Variables are independent of modules and can be used in any Terraform … That way we We want collaboration between the 3rd party's devs and our guys easy so the securing of the state file's storage account would have been a lot easier if it was just allowed to be replaced by a variable. would love to see interpolations in the backend config. Nobody here is wrong. » Configuring Terraform Cloud Variables for HCS on Azure We need to configure a few variables that will tell Terraform Cloud how it can interact with HCS on Azure. Terraform doesn't allow you to interpolate variables within the variables file otherwise you get the error: Error: Variables not allowed. aws-vault, k8s etc.). } Sign in Perhaps it's better to just give accross account access to the user / role which is being used to deploy your terraform. It tells Terraform that you're accessing a variable and that the value of the region variable should be used here. this works fine if i dont use variables. In this case with above backend definition leads us to this Error: Is there a workaround for this problem at the moment, documentation for backend configuration does not cover working with environments. on provider.tf line 11, in terraform: 11: key = var.statefile_name. I also would like to be able to use interpolation in my backend config, using v 0.9.4, confirming this frustrating point still exists. It would be helpful if it were possible to decouple it completely. Other kinds of variables in Terraform include environment variables (set by the shell where Terraform runs) and expression variables (used to indirectly represent a value in an expression ). https://github.com/cloudposse/dev.cloudposse.co Error: Variables not allowed. And will it, if I do this workaround, keep working? So, we are looking at switching to Pulumi as they seem to understand this In Part 2, we introduced the basic syntax and features of Terraform and used them to deploy a cluster of web servers on AWS. Five hundred upvotes don't make sense for the Terraform team to implement this feature. You can also define the values in the variables file. I'm hitting this, too. Successfully merging a pull request may close this issue. Of course, this is just an example which may or not … Seem like you need CI instead of granting devs access to your state, On Tue, 22 Sep 2020, 13:35 KatteKwaad, ***@***. Just ran into this but with a "normal" variable. One of the first steps on the pipeline does: From this point, the runners understands that the 00-backend.tf contains a valid Terraform Backend configuration. key = var.statefile_name "Variables may not be used here" for `prevent_destroy`, ministryofjustice/cloud-platform-terraform-rds-instance#48. You could store the keys in Azure Key Vault, then get it using data provider and use that value for the storage access instead of hardcoded value. I dont know if you tested using Data in the backend block and it worked. Thus the engine is running and interpolation is supported. Terraform Cloud Agents allow Terraform Cloud to communicate with isolated, private, or on-premises infrastructure. concept Hashicorp locked down 3116. We have started to see Terraform as being difficult to secure and this It would be nice if we were able to pass in variables to make the key interchangeable with say a tfvars variable. Better Terraform variable usage - We could map multiple subnet AZ to single variable and use Terraform's functions to map those values. Same issue, trying to create S3 and Dynamo resources for, and deploy another project infrastructure in one flow. The first method we will look at is to use an input variable at the command line this is the simplest of methods and most commonly used for ad-hoc overrides, here we simply add a -var ‘variable_name=”value” as an option for the terraform plan or apply command. It's documented at TF_CLI_ARGS and TF_CLI_ARGS_name. It tells Terraform that you're accessing a variable and that the value of the region variable should be used here. region = "us-east-1" I need to be able to re-run tests over and over. Have a question about this project? https://github.com/cloudposse/prod.cloudposse.co, So we're not granting them access to state as we're tokenizing the value out and securing it in KeyVault but the functionality to handle the process as a first class citizen is what is missing. set lifecycle to prevent destroying anything marked as production. }. I don't find this ideal, but at least I can easily switch between environments and create new environments without having to edit any terraform. Any planned changes? Terraform variables. We’ll occasionally send you account related emails. The Terraform Azure DevOps Provider allows us to be able to create a standard Terraform deployment that creates a Project inside a DevOps Organization. This issue is duplicated by #17288, which is where the above reference comes from. outputs on the other hand are evaluated near the end of a TF life cycle. Try running "terraform plan" to see. The text was updated successfully, but these errors were encountered: prevent_destroy cannot support references like that, so if you are not seeing an error then the bug is that the error isn't being shown; the reference will still not be evaluated. Hi, I don’t represent the hashi team but following this thread and others for awhile I don’t believe there’s any disagreement in its benefit, terraform team is slowing working its way towards it (hcl2 consuming a large part of those 3 years and now working on better support for modules). There are multiple ways to assign variables. And they can contain default values in case no values are submitted during runtime. manually change the token file And indeed, if you comment out the variable reference in the snippet above, and replace it with prevent_destroy = false, it works - and if you then change it back it keeps working. @KatteKwaad What's the problem to process script variables before processing the backend config? I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. backend "azurerm" { Terraform supports multiple different variables types. to your account, Variables are used to configure the backend. Note: For brevity, input variables are often referred to as just "variables" or "Terraform variables" when it is clear from context what sort of variable is being discussed. terraform variables may not be used here. Your top-level structure looks nice and tidy for traditional dev/staging/prod ... sure: But what if you want to stand up a whole environment for project-specific features being developed in parallel? terraform-compliance is providing a similar functionality only for terraform while it is free-to-use and it is Open Source. ", I believe we can close this given the solution provided at #20428 (comment). I'm recategorizing this as an enhancement request because although it doesn't work the way you want it to, this is a known limitation rather than an accidental bug. ***> wrote: What I did though was not optimal; but in my build steps, I ran a bash script that called AWS configure that ultimately set the default access key and secret. I know a +1 does not add much but yeah, need this too to have 2 different buckets, since we have 2 AWS accounts. Terraform variables can be defined within the infrastructure plan but are recommended to be stored in their own variables file. Full control over the paths is ideal, and we can only get that through interpolation. Some things work in Terraform version 0.11 that do not work in version 0.12. trying to create 3x routes into different route tables, each the same route. Now that we have "environments" in terraform, I was hoping to have a single config.tf with the backend configuration and use environments for my states. Deployment is 100% automated for us, and if the dev teams need to make a change to a resource, or remove it then that change would have gone through appropriate testing and peer review before being checked into master and deployed. Sign in Wrapper/Terragrunt seems to be the 2020 solution when you're deploying many modules to different environments. Code changes needed for version 12.

terraform variables may not be used here

terraform variables may not be used here

In the example above project1 might not even have staging... and project2 might have unit/regression/load-testing/staging phases leading to production release. I was hoping to do the same thing as described in #13603 but the lack of interpolation in the terraform block prevents this. A single terraform.tfvars file (automatically loaded by Terraform commands) with all generic variable values, which do not have customized or environment-specific values. I have a list variable containing the different route tables, but keep getting errors and not sure how to progress. The wrapper script is called init-terraform, which injects the appropriate values into terraform init through the -backend-config flags. @apparentlymart, what's the Terraform team's position on this issue? The need to set lifecycle properties as variables is required in a lot of production environments. You can see a screenshot below the variables I’m using in my environment: Here are the variables being used in this demo: Cluster - the address for my HCS Consul endpoint. This is sorely needed Post ... Post category: Terraform; Post comments: 0 Comments; In this post, I will cover terraform variables in-depth. Please allow variables derived from static values to be used in lifecycle blocks. In the end this feature would be hugely helpful, only wanted to provide another perspective on the “long fight” verbiage. These projects often have a few variables (such as an API key for accessing the cloud) and may use dynamic data inputs and other Terraform and HCL features, though not prominently. While it seems like this is being worked on, I wanted to also ask if this is the right way for me to use access and secret keys? a sample policy could be, if you are working with AWS, you should not create an S3 bucket, without having any encryption. P.S. Don’t get me wrong, I still think Terraform is a fantastic tool once you get to know it in further details, but the learning curve can be very steep, specially if you don’t have a good understanding of how the underlying provider works. This would let me effectively use modules to run dev & test environments with the same config as prod, while providing deletion protection for prod resources. seems my local test env was still running on terraform 0.9.1, after updating to latest version 0.9.2 it was working for me. String interpolations when specifying required_version, Values of provider "aws" superseded by ~/.aws/credentials when doing terraform init, s3 remote state still broken for multiple users, Can't count lists in local vars if they contain non-created resources, https://github.com/cloudposse/dev.cloudposse.co, https://github.com/cloudposse/staging.cloudposse.co, https://github.com/cloudposse/prod.cloudposse.co, https://github.com/notifications/unsubscribe-auth/AABJDLT2QK3SAEJDHCREXWLSHCKZ5ANCNFSM4DE5FWTA, Terraform state file should depend on environment, support structured cli configuration inspection, https://www.terraform.io/docs/configuration/variables.html, Allow to interpolate ${var. We don't want the devs to see the storage access key and the MSI approach is not going to work considering the costs of running a vm just to deploy with terraform. 9: storage_account_name = var.statefile_storage_account, on provider.tf line 10, in terraform: env:/${var.env}/project/terraform/terraform.tfstate. — backend "s3" { I've resolved implementing a tool which performs a sort of preprocessing over a .tf, resolving variables (and allowing to include other .tf snippets): Ie: We are also using this approach, I mean, we have a "template" file and we use envsubst to create the final backend.tffile "on the fly" inside the runner. You can't specify a different backend bucket in terraform environments. Home > terraform variables may not be used here. I just finished deploying a 3 stage app, and ended up using workspaces which didn't feel right. Another use case that should be considered is to use a data source for configuring a backend. Is that intended behavior? Looking at my ‘terraform.tfvars’ file I declare specific variables that are applied to my deployment. This is covered pretty well in the Hashicorp Docs here (single page read <5 minutes) and if you have a LinkedIn Learning account check out my Terraform course “Learning Terraform“.. seems variable are not allowed in that block Already on GitHub? @umeat in that case you are right, it is not possible at the moment to use different backends for each environment. Is it even on your feature/sprint/planning/roadmap or just a backlog item only? Revert attempt to parametrize allowing destruction of hub disk. Reply to this email directly, view it on GitHub By deploying lightweight agents within a specific network segment, you can establish a simple connection between your environment and Terraform Cloud which allows for provisioning operations and management. The same of: #3116 If it works for you then "it is" the best solution. storage access key and the MSI approach is not going to work considering Reference: Variables may not be used here. We’ll occasionally send you account related emails. Ideally I'd want my structure to look like "project/${var.git_branch}/terraform.tfstate", yielding: Now, everything you find for a given project is under its directory... so long as the env is hard-coded at the beginning of the remote tfstate path, you lose this flexibility. Variables may not be used here. Can you close, please? Initializing the backend... on provider.tf line 8, in terraform: They push environment management complexity into separate docker images (ex. Even when you don't create a module intentionally, if you use Terraform, you are already writing a module – a so-called "root" module. e.g. I found that Terraform is like perl (does anyone still use perl?) resource_group_name = var.statefile_storage_account_rg AWS RDS has a deletion_protection option that is easy to set. Environment-or-case-specific *.tfvars files with all variable values which will be specific to a particular case or environment, and will be explicitly used when running terraform plan command. to your account. }. Can someone with the inner knowledge of this "feature" work please step up and give us some definitive answers on simple things like: Thanks for your work - Hashicorp - this tool is awesome! Perhaps a middle ground would be to not error out on interpolation when the variable was declared in the environment as TF_VAR_foo? secret_key = "${var.aws_secret_key}" In this first release along the lines of these new capabilities, we’ve focused on input variables & module outputs first, with an additional opt-in experiment for values which provider schemas mark as sensitive. Successfully merging a pull request may close this issue. } 8: resource_group_name = var.statefile_storage_account_rg, on provider.tf line 9, in terraform: Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists... to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). You are receiving this because you are subscribed to this thread. variables.tf. bucket = "ops" We don't want the devs to see the at the expense of developer convenience when cloning the repo and having to Feature request. Complete Step 1 and Step 2 of the How To Use Terraform with DigitalOcean tutorial, and be sure to name the project folder terraform-flexibility, instead of loadbalance. Here is an example of code I used in my previous article: My knowledge is really limited of terraform and have gotten through most bits that I have needed but this i am stuck on. The values can be found in the environment specific .tfvars files. It's over 4 years since #3116 was opened, I think we'd all appreciate some indication of where this is? privacy statement. oh well since after these years this issue is still open i think i will drop the issue i experience on here. This is one of the best threads ever. issue is not helping. As an example of the file structure of this approach, this is what the project we’ll build in … 11: key = var.statefile_name, seems variable are not allowed in that block. Off the top of my head I can think of the following limitations: All of these make writing enterprise-level Terraform code difficult and more dangerous. Not slanting at you, just frustrated that this feature is languishing and I NEED it ... Now.... @Penumbra69 and all the folks on here: I hear you, and the use cases you're describing totally make sense to me. Hello Everyone, Welcome to devopsstack, If you observe our previous… Continue Reading Terraform variables. It's not pretty but it works, and is hidden away in the module for the most part: Module originated prior to 0.12, so those conditionals could well be shortened using bool now. The TF engine is not yet running when the values are assigned. In Terraform 0.10 there will be a new setting workspace_key_prefix on the AWS provider to customize the prefix used for separate environments (now called "workspaces"), overriding this env: convention. Switching which infrastructure you're operating against could be as easy as checking out a different git branch. I wanted to extract these to variables because i'm using the same values in a few places, including in the provider config where they work fine. Prerequisites before all of this. container_name = var.statefile_container Have a question about this project? Variable defaults / declarations cannot use conditionals. My use case is very much like @weldrake13's. All files in your Terraform directory using the .tf file format will be automatically loaded during operations. E.g. As a workaround, since we use the S3 backend for managing our Terraform workspaces, I block the access to the Terraform workspace S3 bucket for the Terraform IAM user in my shell script after Terraform has finished creating the prod resources. storage_account_name = var.statefile_storage_account Microservices are better versioned and managed discretely per component, rather than dumped into common prod/staging/dev categories which might be less applicable on a per-microservice basis, each one might have a different workflow with different numbers of staging phases leading to production release. This use case is pretty straight forward, you can just set the environment variables once and everything will be able to connect. Also I appreciate this is one resource duplicated, and it would be much worse elsewhere for larger configurations. And it works.. Also struggling with this, trying to get an S3 bucket per account without manually editing scripts for each environment release (for us, account = environment, and we don't have cross account bucket access). This value can then be used to pass variables to modules based on the currently configured workspace. ... You may now begin working with Terraform. ‍♂️. S3 Buckets have an mfa_delete option which is difficult to enable. In the mean time, although not ideal, a light wrapper script using cli vars works well. privacy statement. I think this would be even harder to do since the state stores some information regarding what provider is used by which resource. I have created a sample GitHub repo that holds the code examples we are going to look at below. In the video I change the capacity of the virtual machine scale set from 5 to 25. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. could have replaced it via our key vault secrets as we do the others but The way I'm handling this is defining the backend without the "key" parameter. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. <, Using variables in terraform backend config block. the securing of the state file's storage account would have been a lot Terraform installed on your local machine and a project set up with the DigitalOcean provider. You signed in with another tab or window. so while I'm bummed that this doesn't work, I understand that I shouldn't expect it to. We have started to see Terraform as being difficult to secure and this issue is not helping. We have a project that is being developed by a 3rd party and getting deployed in Azure. Same thing for me. We issue dev environments to each dev, and so our backend config would look like. Terraform is not mature yet But I get this error for terraform init >>> I have the same problem i.e. in backend config, but its simple. The reason this works is due to Terraform variable values (and providers) do not support interpolation. For example, the AWS Terraform provider allows you to automatically source local environment variables, which solves the issue of placing secrets in places they should be, ie. In case it's helpful to anyone, the way I get around this is as follows: All of the relevant variables are exported at the deployment pipeline level for me, so it's easy to init with the correct information for each environment. In my use case i need to reuse the same piece of code (without writing a new repo each time i'd want to consume it as a module) to maintain multiple separate statefiles. Trying to run terraform block with variables like so, terraform { I managed to get it working by using AWS profiles instead of the access keys directly. Tedious, but it works. Is the reason for this limitation security? It would be an infrastructure-as-code dream to get this working. The word "backend" can not be found on page https://www.terraform.io/docs/configuration/variables.html. Example here is a module for gcloud sql instance, where obviously in production I want to protect it, but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. Deploying the HA AKS cluster. Variables may not be used here. variables/prod.tfvars; main.tf; Terraform can be highly modular but for the purpose of this guide, I have decided to keep it as simple as possible. It would be more comfortable to have a backend mapping for all environments what is not implemented yet. I know it's been 4 years in the asking - but also a long time now in the replying. By clicking “Sign up for GitHub”, you agree to our terms of service and However, we discovered this behavior because running terraform init failed where it had once worked. We can use the resources to then describe what features we want enabled, disabled, or configured. It is so funny. 1 terraform apply # Without a planfile, supply Terraform variables here Because Terragrunt automates so much, it becomes import to make sure application configuration protects against running into Terraform’s quirks: otherwise, it’s easy to inadvertently pass variables to an apply with a planfile and everything will explode . In my example you could still use terraform environments to prefix the state file object name, but you get to specify different buckets for the backend. Seen multiple threads like this. Disappointing to see that so many messy (IMO) workarounds are still being used because Terraform still can't handle this. I felt there should be a higher level abstraction of each environment such as a folder (terragrunt) or docker image (cloudposse). At the moment we use multiple environments prod/stage and want to upload tfstate files to S3. VPC endpoints - Instead of accessing ECR images through NAT from ECS, we could define VPC Endpoints for ECR, S3 and CloudWatch. no..it has been 3 years and no answer. variables.tf is the home of all the variables but not the values themselves. *} inside backend configuration, terraform.backend: configuration cannot contain interpolations. I've knocked up a bash script which will update TF_VAR_git_branch every time a new command is run from an interactive bash session. The end user's backend is not of concern to our terraform configuration. encrypt = "true" Please note: I do not use real code examples with some specific provider like AWS or Google intentionally, just for the sake of simplicity. provider "aws" { - region = "us-west-2" + region = var.region } This uses the variable named region, prefixed with var.. Instead we now have to do a nasty workaround by tokenizing that access key writing the keys into configurations or state. Already on GitHub? It would be nice to understand why this can't work. Thought I'd offer up a work around I've used in some small cases. Terraform modules You already write modules. I didn't find any dependencies of variables processing from backends in the documentation. party and getting deployed in Azure. I really like CloudPosse's solution to this problem. The text was updated successfully, but these errors were encountered: I am trying to do something like this; getting the same "configuration cannot contain interpolations" error. Extract the binary to a folder. -backend-type=s3 , -backend-type=kubernetes , etc.. dev.acme.com, staging.acme.com, prod.acme.com) and modify the backend variables in each environments Dockerfile. Almost 4 years in the making and still not fix to this? Extract the binary to a folder. I am on the most current version of Terraform. Instead I have to use the role_arn in the backend config which can't contain the interpolation I need. Have a basic understanding of how to use Terraform and what it does. You signed in with another tab or window. It configures the AWS provider with the given variable. This effectively locks down the infrastructure in the workspace and requires a IAM policy change to re-enable it. We’re excited to announce that Terraform 0.14 includes the ability to thread the notion of a “sensitive value” throughout Terraform. Add the folder to the path environment variable so that you can execute it from anywhere on the command line. I would also appreciate if Terraform allows variables for specifying "prevent_destroy" values. If this gets closed then those following cant view the issue. There is an ongoing issue (#3116) which is currently open but @teamterraform seem to have made that private to contributors only. Though this might require making such variables immutable? Once the change is applied, Azure is quick to deploy these (remember, this all depends on datacentre capacity). Commenting on #3119 was locked almost 2 years ago saying "We'll open it again when we are working on this". Here is the error Output of terraform validate: I needs dis! Terraform will split and store environment state files in a path like this: @NickMetz it's trying to do multiple environments with multiple backend buckets, not a single backend. Terraform does not yet have native support for decrypting files in the format used by sops.One solution is to install and use the custom provider for sops, terraform-provider-sops.Another option, which I’ll demonstrate here, is to use Terragrunt, which has native sops support built in. This way we could keep all the traffic on the private network. Instead we now have to do a nasty workaround by tokenizing that access key at the expense of developer convenience when cloning the repo and having to manually change the token file, So, we are looking at switching to Pulumi as they seem to understand this concept. terraform apply -var region=”eu-west-1” I write tests for my modules. Since key is a required parameter, terraform prompts me for it. It would be create if we can use variables in the lifecycle block because without using variables I'm literally unable to use prevent_destroy in combination with a "Destroy-Time Provisioner" in a module. We want collaboration between the 3rd party's devs and our guys easy so This is particularly useful if HashiCorp Vault is being used for generating access and secret keys. Terraform users describe these configurations -- for networking, domain name routing, CPU allotment and other components -- in resources, using the tool's configuration language.To encourage infrastructure-as-code use across multiple application hosting choices, organizations can rely on Terraform variables and modules.Variables are independent of modules and can be used in any Terraform … That way we We want collaboration between the 3rd party's devs and our guys easy so the securing of the state file's storage account would have been a lot easier if it was just allowed to be replaced by a variable. would love to see interpolations in the backend config. Nobody here is wrong. » Configuring Terraform Cloud Variables for HCS on Azure We need to configure a few variables that will tell Terraform Cloud how it can interact with HCS on Azure. Terraform doesn't allow you to interpolate variables within the variables file otherwise you get the error: Error: Variables not allowed. aws-vault, k8s etc.). } Sign in Perhaps it's better to just give accross account access to the user / role which is being used to deploy your terraform. It tells Terraform that you're accessing a variable and that the value of the region variable should be used here. this works fine if i dont use variables. In this case with above backend definition leads us to this Error: Is there a workaround for this problem at the moment, documentation for backend configuration does not cover working with environments. on provider.tf line 11, in terraform: 11: key = var.statefile_name. I also would like to be able to use interpolation in my backend config, using v 0.9.4, confirming this frustrating point still exists. It would be helpful if it were possible to decouple it completely. Other kinds of variables in Terraform include environment variables (set by the shell where Terraform runs) and expression variables (used to indirectly represent a value in an expression ). https://github.com/cloudposse/dev.cloudposse.co Error: Variables not allowed. And will it, if I do this workaround, keep working? So, we are looking at switching to Pulumi as they seem to understand this In Part 2, we introduced the basic syntax and features of Terraform and used them to deploy a cluster of web servers on AWS. Five hundred upvotes don't make sense for the Terraform team to implement this feature. You can also define the values in the variables file. I'm hitting this, too. Successfully merging a pull request may close this issue. Of course, this is just an example which may or not … Seem like you need CI instead of granting devs access to your state, On Tue, 22 Sep 2020, 13:35 KatteKwaad, ***@***. Just ran into this but with a "normal" variable. One of the first steps on the pipeline does: From this point, the runners understands that the 00-backend.tf contains a valid Terraform Backend configuration. key = var.statefile_name "Variables may not be used here" for `prevent_destroy`, ministryofjustice/cloud-platform-terraform-rds-instance#48. You could store the keys in Azure Key Vault, then get it using data provider and use that value for the storage access instead of hardcoded value. I dont know if you tested using Data in the backend block and it worked. Thus the engine is running and interpolation is supported. Terraform Cloud Agents allow Terraform Cloud to communicate with isolated, private, or on-premises infrastructure. concept Hashicorp locked down 3116. We have started to see Terraform as being difficult to secure and this It would be nice if we were able to pass in variables to make the key interchangeable with say a tfvars variable. Better Terraform variable usage - We could map multiple subnet AZ to single variable and use Terraform's functions to map those values. Same issue, trying to create S3 and Dynamo resources for, and deploy another project infrastructure in one flow. The first method we will look at is to use an input variable at the command line this is the simplest of methods and most commonly used for ad-hoc overrides, here we simply add a -var ‘variable_name=”value” as an option for the terraform plan or apply command. It's documented at TF_CLI_ARGS and TF_CLI_ARGS_name. It tells Terraform that you're accessing a variable and that the value of the region variable should be used here. region = "us-east-1" I need to be able to re-run tests over and over. Have a question about this project? https://github.com/cloudposse/prod.cloudposse.co, So we're not granting them access to state as we're tokenizing the value out and securing it in KeyVault but the functionality to handle the process as a first class citizen is what is missing. set lifecycle to prevent destroying anything marked as production. }. I don't find this ideal, but at least I can easily switch between environments and create new environments without having to edit any terraform. Any planned changes? Terraform variables. We’ll occasionally send you account related emails. The Terraform Azure DevOps Provider allows us to be able to create a standard Terraform deployment that creates a Project inside a DevOps Organization. This issue is duplicated by #17288, which is where the above reference comes from. outputs on the other hand are evaluated near the end of a TF life cycle. Try running "terraform plan" to see. The text was updated successfully, but these errors were encountered: prevent_destroy cannot support references like that, so if you are not seeing an error then the bug is that the error isn't being shown; the reference will still not be evaluated. Hi, I don’t represent the hashi team but following this thread and others for awhile I don’t believe there’s any disagreement in its benefit, terraform team is slowing working its way towards it (hcl2 consuming a large part of those 3 years and now working on better support for modules). There are multiple ways to assign variables. And they can contain default values in case no values are submitted during runtime. manually change the token file And indeed, if you comment out the variable reference in the snippet above, and replace it with prevent_destroy = false, it works - and if you then change it back it keeps working. @KatteKwaad What's the problem to process script variables before processing the backend config? I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. backend "azurerm" { Terraform supports multiple different variables types. to your account, Variables are used to configure the backend. Note: For brevity, input variables are often referred to as just "variables" or "Terraform variables" when it is clear from context what sort of variable is being discussed. terraform variables may not be used here. Your top-level structure looks nice and tidy for traditional dev/staging/prod ... sure: But what if you want to stand up a whole environment for project-specific features being developed in parallel? terraform-compliance is providing a similar functionality only for terraform while it is free-to-use and it is Open Source. ", I believe we can close this given the solution provided at #20428 (comment). I'm recategorizing this as an enhancement request because although it doesn't work the way you want it to, this is a known limitation rather than an accidental bug. ***> wrote: What I did though was not optimal; but in my build steps, I ran a bash script that called AWS configure that ultimately set the default access key and secret. I know a +1 does not add much but yeah, need this too to have 2 different buckets, since we have 2 AWS accounts. Terraform variables can be defined within the infrastructure plan but are recommended to be stored in their own variables file. Full control over the paths is ideal, and we can only get that through interpolation. Some things work in Terraform version 0.11 that do not work in version 0.12. trying to create 3x routes into different route tables, each the same route. Now that we have "environments" in terraform, I was hoping to have a single config.tf with the backend configuration and use environments for my states. Deployment is 100% automated for us, and if the dev teams need to make a change to a resource, or remove it then that change would have gone through appropriate testing and peer review before being checked into master and deployed. Sign in Wrapper/Terragrunt seems to be the 2020 solution when you're deploying many modules to different environments. Code changes needed for version 12.
