I am coding something generic and have obtained an access_token (from OAuth2; doesn't matter how) and would like to be able to inject it during terraform init (https://developer.hashicorp.com/terraform/language/settings/backends/gcs#access_token). I'm hitting this, too. Are there any chances that we'll have this ability in future versions? In the case of production, this will decrease the risk of sensitive data leakage from the state if production access credentials will be compromised. The same of: #3116 I had the same issue, but my problem was the missing quotes around default value of the variable. Is that intended behavior? It was failing as I had not encapsulated a variable with quotes when passing a secret variable from CI/CD. Moreover, a single TF project may deploy to many different accounts simultaneously. How do two equations multiply left by left equals right by right? Variables may not be used here I'm trying to combine variables into other variables. Just installed the latest version (1.0.0). This can be useful when running Terraform in automation, or when running a variable "aad_allowed_tenants" { This is something I've been wanting for a while and have been thinking a lot about. Perhaps a middle ground would be to not error out on interpolation when the variable was declared in the environment as TF_VAR_foo? This functionality allows you to share modules across different may treat the entire block as redacted. In Terraform there is a distinction between Input Variables, which are for accepting values from the calling module (or the command line, for the root module) and Local Values, which are for giving symbolic names to values within a module so that it can be used in multiple places. Full control over the paths is ideal, and we can only get that through interpolation. Multiple matching workspaces: Terraform will prompt you to select a workspace from the list. By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy.

Outlook needs password but dialog box disappears, Known HDD user password not working on new Bios. Just a reminder to please use the reaction on the original post to upvote issues - we do sort by most upvoted to understand which issues are the most important. Because the input variables of a module are part of its user interface, you can Sensitive Data in State. Well occasionally send you account related emails. One very specific complexity with this is that currently modules need to be pre-fetched using terraform get prior to terraform plan, and currently that command does not take any arguments that would allow you to set variables. from the perspective of the user of the module rather than its maintainer. This happens for resource types where Our modules need to be capable of having lifecycle as variables. Should the alternative hypothesis always be the research hypothesis?

BR, Sign in This is not a bad idea but it is very hard to do with the current architecture of how modules work with Terraform. Variables are not available in this scope? workspace variables to Terraform. Also be sure what type of object you are receiving: is it a list? Does it have to be placed here so that I don't have to check the access and secret keys to github, terraform { Interpolations in terraform {} configuration block. peer-cidr = "192.10.0.0/16" literal expressions However, the s3 backend docs show you how you can partition some s3 storage based on the current workspace, so each workspace gets its own independent state file. Revert attempt to parametrize allowing destruction of hub disk. Wow :) I'm having to provision an backend.tf and not trying to add access_key and secret_key to git and instead export as an env var as that works locally and in a Pipeline. Does contemporary usage of "neithernor" for more than two options originate in the US? - Marcin. The current, beware, if it's for separating environments, workspaces is not suitable for this, as stated in the docs. Check the terraform version. How do philosophers understand intelligence (beyond artificial intelligence)? environment variables (set by the shell where Terraform runs) and expression How to determine chain length on a Brompton? Already on GitHub? Using things like basename(path.cwd) also don't work, sadly. 'content' not support variable. Has Hashicorp given any reasoning as to why they're not fixing this? intended to export it. One matching workspace: Terraform will automatically select the workspace for you.

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! so the required environment variable name will usually have a mix of upper Sorry you are having an issue with this, but the configuration_aliases argument was added in the 0.15 release. In this case, when dealing with review/staging deployment, many people may have admin access to the infra but they will not break the state. Content Discovery initiative 4/13 update: Related questions using a Machine How to concatenate S3 bucket name in Terraform variable and pass it to main tf file. We use this http://bensnape.com/2016/01/14/terraform-design-patterns-the-terrafile/ I think it would be reasonable to have something like that natively. org-name = "${local.orgname}" backend "s3" { All Answers or responses are user generated answers .

You might also like: Why DevOps Engineers Recommend Spacelift 5 Ways to Manage Terraform at Scale followed by the name of a declared variable. the environment of its own process for environment variables named TF_VAR_ Can I ask for a refund or credit next year? 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). For 0.13, see the 0.13 docs, and specifically: The subdirectory ./tunnel must then contain proxy configuration blocks like the following, to declare that it requires its calling module to pass configurations with these names in its providers argument: Powered by Discourse, best viewed with JavaScript enabled, Configuration_aliases within module results in "Variables may not be used here." And how to capitalize on that? Swing and a miss on this one. terraform init -backend-config=backend.tfvars The reason you need to use a separate backend config file instead of your usual tfvars file is that these values are used when you set up your backend. <, With workarounds being provided and they intentionally made it this way, not likely we will see parameters in the source line. I write tests for my modules. Though this might require making such variables immutable? I'm going to lock this issue because it has been closed for 30 days . Why does the second bowl of popcorn pop better in the microwave? rev2023.4.17.43393. the variable is considered to be optional and the default value will be used I am trying to pass aws alias configuration down into a module, where in the module its specified like this: When trying to plan this configuration (with TF-12.x or TF-13.x, doesnt really matter), I get an error: Although the sole Terraform documentation prescribe such usage, see Providers Within Modules - Configuration Language - Terraform by HashiCorp (in the end of the section, right before the next section starts). You signed in with another tab or window. Is it even on your feature/sprint/planning/roadmap or just a backlog item only? So why make it so we have to employ workarounds to make something this basic work? Would be weird. terraform plan -var='aad_allowed_tenants=["aasdfad"]' providers = { value definition. Local Values. If you use a sensitive value as part of an encrypt = "true" Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Has Hashicorp given any reasoning as to why they're not fixing this? See the terraform documentation on partial configuration for more details. I agree most of the problems they are solving are artificial. You still cannot put variables in backend.conf, which was the initial question. Variables may not be used here. We notice that terraform raises a warning about assigning a value to an undeclared variable. Can terraform backend fields be accessed as variables? That setup does have permissions issues but it is still possible. I'm trying to avoid hard-coding module sources; the simplest approach would be: The result I get while attempting to run terraform get -update is. Add support for git tags/branches in module sources, config/module: validate config to load [GH-1439]. Asking for help, clarification, or responding to other answers. except the following: source, version, providers, count, for_each, lifecycle, depends_on, locals. although it didnt solve my original problem, Installing version 0.15.1 of terraform fixes For example, the following configuration: Will cause Terraform to warn you that there is no variable declared "mosse", which can help For more information, see to your account, https://gist.github.com/steinybot/6d6fed5c27d7eb919a1c939521d57c20.

Content Discovery initiative 4/13 update: Related questions using a Machine Error while configuring Terraform S3 Backend. However, I am trying to use it with assume_role_tags on s3 backend. When using the -var parameter, you should ensure that what you are passing into it will be properly interpreted by HCL. The source parameter would be: Without having looked at the code, fixing such "small" issues might actually cascade into a massive amount of codebase rewrite, if hitting architectural limits. Hashicorp locked down 3116. If I flip to bash, using the exact same terraform.exe, it works. 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). We use GitHub issues for tracking bugs and enhancements, rather than for questions. briefly describe the purpose of each variable using the optional Hi @rosshettel. Is there any particular reason behind that? source = "./iam/customer/${local.orgname}" The only reason I'm actually using terragrunt is because native terraform has a limitation on the backends where we have to hardcode values. aws = "aws.customer-${local.orgname}" Some special rules apply to the -var command line option and to environment But it should not be closed. files, but consists only of variable name assignments: Terraform also automatically loads a number of variable definitions files $ terraform plan -var 'compartment_id=abcd.1234'. For example, at a bash prompt on a Unix system: On operating systems where environment variable names are case-sensitive, but more ephemeral environments I want to be able to pull the environment down without editing the code temporarily. The rationale to disallow this so that intelligent people can't download random modules is the same as not having a division operator as somebody may decide to divide by zero one day. when alias name is unquoted, Providers Within Modules - Configuration Language - Terraform by HashiCorp. The fix is to add the validation so you get something a bit more clear rather than "error downloading module" I guess. It was requested by so many people! I don't really want to use terragrunt, but its the only way I can use variables to populate my backend information. You can't specify a different backend bucket in terraform environments. (again obviously not an ideal situation). resource "some_resource" "a" will also be hidden in the plan output: In some cases where you use a sensitive variable inside a nested block, Terraform I believe the blocker is that to support this feature one would need to implement pre-processing of the configuration. Again, please do not quote me on that technical explanation; this is how I understand the underlying issue but I may be a little off-base. hashicorp/terraform-provider-google#11742. pretty ugly :-). Thanks for contributing an answer to Stack Overflow! @mitchellh - It would be great if hashicorp could re-look at this. If nullable is false and the variable has a Use pre-installed Terraform plugins instead of downloading them with terraform init. My module supports figuring out if the user specified an existing repo or the repo needs to be created. It would be nice to understand why this can't work. (I've done this several times while debugging, in fact.). 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. The supported type keywords are: The type constructors allow you to specify complex types such as For more information on quoting and escaping for -var arguments, you to also mark the output value itself as sensitive, to confirm that you Error: Variables not allowed I want to default this to "true", but permit users to override it with variables to the module for ephemeral environments. So in addition to giving the backend bucket name and key in tfvars, I should also create an TF_CLI_ARGS_init environment variable? The default value for nullable is true. Instead I have to use the role_arn in the backend config which can't contain the interpolation I need. Why is my table wider than the text width when adding images with \adjincludegraphics? foo1: foo2.tf. 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. Variables are not available in this scope? Already on GitHub? bucket = var.backend_bucket_name For example, in a Unix-style shell: However, if a root module variable uses a type constraint Luckily I have my.terraform directory in the .gitignore. locals { but from commandline, I try to overwrite it using Storing configuration directly in the executable, with no external config files. Go, NodeJS or Python I don't use any runtime features to solve it, but rather I just ignore the location/version of the module given in the dependency list and just install whatever one I want, exploiting the fact that (just like in Terraform) the "get" step is separated from the "compile" and "run" steps, and so we can do manual steps in between to arrange for the versions we want. env = "production" definitions files, which requires careful attention to the string escaping rules Create a backend yaml file for each and use the one you need, @FernandoMiguel That's exactly what I'm trying to avoid. I can do this in "provider" blocks as the provider block allows interpolations so I can assume the relevant role for the environment I'm deploying to, however if I also rely on the role being set for the backend state management (e.g. 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.
