Variables are not available in this scope? 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. 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. Is Hashcorp looking to resolve this issue? value meant for a variable declaration, but perhaps there is a mistake in the I wish terraform did this natively. Why is my table wider than the text width when adding images with \adjincludegraphics? GThoro 2 yr. ago Put t2.small in double quotes. I would also appreciate if Terraform allows variables for specifying "prevent_destroy" values. Interpolations in terraform {} configuration block. I see two things that could be causing the error you are seeing. I want to use ${terraform.workspace} variable in terraform scope. Individually, with the -var command line option. @gsirvas @umeat To archive multiple environment with the same backend configuration it is not necessary to use variables/interpolation .It is expected that is not possible to use variables/interpolation in backend configuration see comment from @christofferh. The chosen direction to implement support for just the version is very limiting. You just can't specify a distinct bucket for each workspace. all of the blocks of a particular type are required to be unique, and so +1. #30937. Find centralized, trusted content and collaborate around the technologies you use most. I have a git-based module to configure team permissions, and I have ~80 teams. b. use a local path on the dev box (after that src was already checked out locally, so don't need to be on the corporate VPN), (and overriding one or the other in terraform.tfvars) and then. configuration. Ideally I'd want my structure to look like "project/${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. How to determine chain length on a Brompton? In the case of production, this will decrease the risk of sensitive data leakage from the state if production access credentials will be compromised. 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. I feel that many (all?) providers = { Thanks for listening :). 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. New external SSD acting up, no eject option. We conclude the difference as that the variables.tf just declare valid variables and optionally their types, and the tfvars file assigns them values. "variables" or "Terraform variables" when it is clear from context what sort of Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. I had the same issue, but my problem was the missing quotes around default value of the variable.

How do philosophers understand intelligence (beyond artificial intelligence)? Can a rotating object accelerate by changing shape? Or even something like source yaml_lookup://../lookupfile.yaml which contains module name and source pairs. I wrote my comment just to rise the issue up and let people know that more people are desiring that feature. source = "./s3/customer/${local.orgname}" Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. rev2023.4.17.43393. You cannot use variables in variable files it will cause cyclic dependency. Refactor database credentials Open main.tf in your text editor.

I am using Terraform v0.9.4. A typical tfvars file should contain the variables that you want to pass to Terraform. I had something similar , the module was written on version 1.0 and I was using terraform version 0.12. commentary for module maintainers, use comments. I don't really want to use terragrunt, but its the only way I can use variables to populate my backend information. If your .tfvars file is in another directory you must provide it as a -var-file parameter. What if for some reason we decide to change the company name and company policy mandates that we change the bucket names? I hope that you didn't want to store tf-state in one AWS account, but prepare environments in others as somebody asked here. So, a temporary workaround: TL;DR: Use sed to replace the template file and create the target main.tf. lol what? I'm going to keep this tagged with "thinking". the previous values. 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. Same issue experienced here as well, posting my specific error to help future googlers (my output is slightly different due to me wrapping my config with Terragrunt): The following produced the similar error as @steinybot. Terraform does not allow this natively: variable nickname { default = var.fullname } variable fullname { default = "richard" } output name { value = var.nickname } $ terraform apply Error: Variables not allowed on var-to-var.tf line 2, in variable "nickname": 2: default = var.fullname Variables may not be used here. So try InstanceType = "t2.small" It also shifts a lot of potential errors away from a compile-time error to a runtime error, which we've wanted to avoid. So in addition to giving the backend bucket name and key in tfvars, I should also create an TF_CLI_ARGS_init environment variable? to assign complex-typed values, like lists and maps. For more information on shell quoting, including additional This can be useful when running Terraform in automation, or when running a If employer doesn't have physical address, what is the minimum information I should have from them? Add support for git tags/branches in module sources, config/module: validate config to load [GH-1439]. I got it by providing a list variable with following input: [name1,name2,name3] 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. We were able to get around this by using backend-config when initializing the Terraform project as shown below. on main.tf line 19, in terraform: project_id = "gcp-terraform-307119" location = "europe-central2". declare an attribute as sensitive, same error. 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. Terraform's usual syntax for The current method allows plenty of room for human error. (It would also be nice to extend terraform get to be able to handle certain overrides itself, but that is made more complex by the fact that there can be nested modules that have their own dependencies, and so such syntax would probably end up quite complicated if it had to happen entirely on the command line.). Sign in I'm trying to the the same as @NickMetz, I'm running terraform 0.9.3, This is the message when I try to run terraform init. Making statements based on opinion; back them up with references or personal experience. more information on the meaning and behavior of these different types, as well Cc: Garin Kartes , Comment I was able to work around this by creating per-environment override files which are copied into place as part of the deployment pipeline. I think the recommended workaround is find-and-replace value before running terraform :(, Wow this is a real problem so either we duplicate all resources with prevent_destroy, you we use m4 or something to do a search for this (like you have to do with Dockerfiles. env = "production" privacy statement. The problem is that I want to assume an AWS role based on the environment I'm deploying to. +, - (subtraction) >, >=, <, <=. And will it, if I do this workaround, keep working? We use workspaces for different AWS environments and wanted to use different buckets for each workspace, but it looks like it is not possible. 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. Input variables let you customize aspects of Terraform modules without altering 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. I have # At least one attribute in this block is (or was) sensitive, random_pet.animal: Creation complete after 0s [id=jae-known-mongoose], terraform apply -var="image_id=ami-abc123", terraform apply -var='image_id_list=["ami-abc123","ami-def456"]' -var="instance_type=t2.micro", terraform apply -var='image_id_map={"us-east-1":"ami-abc123","us-east-2":"ami-def456"}', terraform apply -var-file="testing.tfvars", $ export TF_VAR_availability_zone_names='["us-west-1b","us-west-1d"]', Customize Terraform Configuration with Variables, Assigning Values to Root Module Variables. And how to capitalize on that? Sensitive Resource Attributes. (, "https://your_src_system/your_project//terraform", "/Users/joeshmoe/projects/your_project/terraform", GoogleCloudPlatform/terraform-google-nat-gateway#67, kinvolk-archives/lokomotive-kubernetes#35. I agree most of the problems they are solving are artificial. Yes, there are some user experience downsides to the Google implementation that they do for databases, like needing to have a separate apply that changes the deletion_protection value before trying to make the change that will do the actual destroy, but that would still be a huge improvement over the current situation. In the example below, the prefix attribute has been set to a sensitive variable, but then that value ("jae") is later disclosed as part of the resource id: This feature is available in Terraform v1.1.0 and later. Is there any sort of solution besides upgrade to 0.15? So instead this worked for me: security_groups_allow_to_msk_on_port_2181 = concat(var.security_groups_allow_to_msk_2181, [data.aws_security_group.client-vpn-sg.id]). be unique among all variables in the same module.
