Some special rules apply to the -var command line option and to environment See https://www.terraform.io/docs/configuration/locals.html. If you have a factory that makes street gates, does it not have to move one of them outside to install in the factory entrance? How can I detect when a signal becomes noisy? key = "terraform/state/ops-com" This would cause issues because now the changes I intended for account B was actually made to account A. that value. That setup does have permissions issues but it is still possible. Can we please add var support in the terraform backend file. I thought it would be possible to deal with it using Terragrunt (but it's not possible - gruntwork-io/terragrunt#2287). "The id of the machine image (AMI) to use for the server. My use-case was inside a module that uses the Github provider. You can only specify one bucket for all workspaces, but the s3 backend will add the workspace prefix to the path: When using a non-default workspace, the state path will be /workspace_key_prefix/workspace_name/key (see also the workspace_key_prefix configuration). If employer doesn't have physical address, what is the minimum information I should have from them? default value, then Terraform uses the default when a module input argument is null. The same of: #3116 declared as variable names. You still cannot put variables in backend.conf, which was the initial question. Please vote for the answer that helped you in order to help others find out which is the most helpful answer. Passing a Use a -var or -var-file command line argument to provide a value for this variable. Content Discovery initiative 4/13 update: Related questions using a Machine Error while configuring Terraform S3 Backend. Variables may not be used here. It may not display this or other websites correctly. 'content' not support variable. Funny thing is when I do it with another variable, that has the same structure, I don't get this error. if they are present: Files whose names end with .json are parsed instead as JSON objects, with Sign in (again obviously not an ideal situation). I'm getting a similar error. 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. Is there any sort of solution besides upgrade to 0.15? So with all of this said, perhaps Terraform could just be a little more transparent about where it looks for modules and embrace the idea that terraform get just installs the default module locations, but it's fine to manually install from other locations, or even to write your own separate tool to install from wherever you want. terraform apply Error: Variables not allowed on vars.tf line 57, in variable "iam_roles_policies_team": 57: aws_iam_policy.test.arn, Variables may not be used here. To learn more, see our tips on writing great answers. Please make the question in SO, as terraform should not be on SF. Already on GitHub? although it didnt solve my original problem, Installing version 0.15.1 of terraform fixes We conclude the difference as that the variables.tf just declare valid variables and optionally their types, and the tfvars file assigns them values. No, can be done from the inside as well. Though this might require making such variables immutable? We were able to get around this by using backend-config when initializing the Terraform project as shown below. I've got a variable declared in my variables.tf like this: This error can also occurs when trying to setup a variable's value from a dynamic resource (e.g: an output from a child module): Using locals block instead of the variable will solve this issue: I had the same error, but in my case I forgot to enclose variable values inside quotes (" ") in my terraform.tfvars file. By clicking Sign up for GitHub, you agree to our terms of service and Our powershell wrapper does so many things to over come terraform restrictions, we cant use terraform without, basically we did something like the guys in terragrunt did, plus many more addons on it, i cant understand how somebody can even use terraform as is out of the box without some interpolation in those missing places.. anyhow, i really hope hashicorp will decide to change some parts of the product, because it is really constricting, some of those things should have been thought of much before. Is Hashcorp looking to resolve this issue? combination. value definition. Terraform will still record sensitive values in the state, I want to call out that this is the root cause of a ton of other issues and work arounds that providers are either being asked to do or doing like: I do understand what @crw is saying in #22544 (comment), but if the Google provider is able to implement this on their own, I don't see why Terraform core cannot as well. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. Reply to this email directly, view it on GitHub Yeah, we've been using the Terrafile approach (see my comment above) it works pretty well but it forces us to use a wrapper script, I think that the Terrafile pattern should be supported by Terraform. But it was suggested only for cases when you work in different AWS accounts. value from within the module. In it, the required_providers block specifies the provider and provider version required by the configuration. You might also like: Why DevOps Engineers Recommend Spacelift 5 Ways to Manage Terraform at Scale You could checkout terragrunt, which is a thin wrapper that provides extra tools for keeping your configurations DRY, working with multiple Terraform modules, and managing remote state. Error: Variables not allowed on <value for var.image_id_map> line 1: (source code not available) Variables may not be used here. You say in your question that your variables are in a file variables.tf which means the terraform plan command will not automatically load that file. 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. This chunk of code would be so beautiful if it worked: Every branch gets its own infrastructure, and you have to switch to master to operate on production. 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. Terraform version: v0.12.8 provider.aws: version = "~> 2.35" And one dynamo table will suffice for all workspaces. the caller may still use null in nested elements or attributes, as long as Initializing the backend 73 terraform. We notice that terraform raises a warning about assigning a value to an undeclared variable. A local value assigns a name to an expression , so you can use the name multiple times within a module instead of repeating the expression. Well occasionally send you account related emails. org-name = "${local.orgname}" ", "The image_id value must be a valid AMI id, starting with \"ami-\".". as sensitive themselves, and so in the above example the two arguments of collections: The keyword any may be used to indicate that any type is acceptable. compare Terraform modules to function definitions: Note: For brevity, input variables are often referred to as just Using separate config file during each TF run is not useful at all. env = "production" For many features being developed, we want our devs to spin up their own infrastructure that will persist only for the length of time their feature branch exists to me, the best way to do that would be to use the name of the branch to create the key for the path used to store the tfstate (we're using amazon infrastructure, so in our case, the s3 bucket like the examples above). Sure, this "works", but it is completely against the very purpose of Terraform, which is to declaratively store a complete picture of resources as code. Error: Variables not allowed on provider.tf line 12, in terraform: 12: dynamodb_table = "data-pf-snowflake-terraform-state-lock-$ {terraform.workspace}" Variables may not be used here. I know a +1 does not add much but yeah, need this too to have 2 different buckets, since we have 2 AWS accounts. account for the possibility of the variable value being null. environment variables (set by the shell where Terraform runs) and expression Frankly it's nuts this hasn't been addressed yet. This is a change from previous versions of Terraform, which It also shifts a lot of potential errors away from a compile-time error to a runtime error, which we've wanted to avoid. Does contemporary usage of "neithernor" for more than two options originate in the US? You just can't specify a distinct bucket for each workspace. FIX: rename variables.tf to variables.tfvars watch out for the types. Deploying your terraform to a different account, but using the same backend bucket. Error: Variables not allowed Can a rotating object accelerate by changing shape? Experiencing this too when I try to pass input a file to plan. Changing module versions manually is error prone. Yes, it was the map var that was causing the problem. Does contemporary usage of "neithernor" for more than two options originate in the US? Using things like basename(path.cwd) also don't work, sadly. } Refer to Custom Condition Checks for more details. In the case of production, this will decrease the risk of sensitive data leakage from the state if production access credentials will be compromised. Thanks! A use I see easily popping up (in that literally my first project that I'm working on terraform with), I want to have multiple modules that I pull from, but I will always want those to use same branch, within a project: which seems pretty reasonable to me - when I pass in git_tag=prod_git_tag, now they all reference the same git_tag and can be updated with one line, rather than in all the various places. There is a similar issue in not being able to use interpolation syntax when providing configuration for back ends (say S3 bucket/region). providers = { where
