I need to be able to pass variable. Works great. Input variables let you customize aspects of Terraform modules without altering be unique among all variables in the same module. For example, the following configuration: Will cause Terraform to warn you that there is no variable declared "mosse", which can help S3 Buckets have an mfa_delete option which is difficult to enable. If you provide values for undeclared variables defined as environment variables 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). to your account. Can't we pass the bucket and key names for backend through. Error: No value for required variable on variables.tf line 1: 1: variable " foo " { The root module input variable " foo " is not set, and has no default value. Since terraform_remote_state is just a regular resource its configuration arguments can be interpolated, even by things that aren't known until apply time, as long as a dependency cycle doesn't result. WHY?? you spot this mistake. We should add validation that this isn't allowed. Perhaps a middle ground would be to not error out on interpolation when the variable was declared in the environment as TF_VAR_foo? Error: variables not allowed Variables may not be used here Terraform workaholicrohit April 15, 2021, 10:42am #1 Hi, I'm continuously getting below error when trying to deploy code files using AWS CodePipeline service, the same code files work with Azure DevOps pipeline.

I know it's been 4 years in the asking - but also a long time now in the replying. The best workaround I have found is by using putting something like this in override.tf. app2: ../repo1/foo2.tf 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. ^This. We are trying to give our development teams control of their infrastructure whilst maintaining standards using modules. ubuntu 22.04: wow to force i3 use default ubuntu 22's file choose dialog? 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. block: The label after the variable keyword is a name for the variable, which must Thanks for your interest in this issue! Can someone please tell me what is written on this score? The Terraform configuration must be valid before initialization so that Terraform can determine which modules and providers need to be installed. When I gave backend bucket name and key in .tfvars, I got the error as I explained in my question. I was hoping to do the same thing as described in #13603 but the lack of interpolation in the terraform block prevents this. Sign in How can I drop 15 V down to 3.7 V to drive a motor?

Forgive me - I'm lost here, due to labels - that is - marked bug, yet your comment suggest a wontfix, marked bug, yet your comment suggest a wontfix. the calling module should pass values in the module block. Using things like basename(path.cwd) also don't work, sadly. This feature was introduced in Terraform v0.14.0. Do not hesitate to share your thoughts here to help others. Thanks for the save samirshaik. The fix is to add the validation so you get something a bit more clear rather than "error downloading module" I guess. Changing module versions manually is error prone. How do philosophers understand intelligence (beyond artificial intelligence)? @rootsher With terragrunt just switch the backend to using a generate block and not the terragrunt native backend block. Terraform reads all of your *.tf files (under your working directory) as one giant script during run time, so you only need to declare your variables once.

(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.). Variables are not available in this scope? That means they need to be provided when you run terraform init, not later when you use the backend with commands like terraform apply.

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. Connect and share knowledge within a single location that is structured and easy to search. Adding required parameters from the command line, in the absence of being able to actually using variables within backend, is simply suboptimal. value from within the module. Use a -var or -var-file command line argument to provide a value for this variable. Terraform obscures this ability a little by storing the local modules in a directory named after the MD5 hash of the module name under the .terraform directory, so it's harder to recognize which one is which by eye but you can, if you locate the right one, install it from a different source or modify it in-place. 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. JavaScript is disabled. Said another way, TF as it is right now gives me a lot of compile time and runtime errors. i.e. I'd rather just have the tf vars file for each environment. the module's own source code. +1. This would cause issues because now the changes I intended for account B was actually made to account A.

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. when running terraform env select) it doesn't work. The current, beware, if it's for separating environments, workspaces is not suitable for this, as stated in the docs. Terraform will split and store environment state files in a path like this: Obviously, quoting the value results in provider configuration not been passed properly into the module. This functionality allows you to share modules across different } Echoing the use case for generated credentials being able to be generated and used in another provider but not being able to use the same credentials for lets say a S3 backend which makes it pointless to generate the credentials inside of a terraform run and must now move these to outside of terraform completely. You can specify custom validation rules for a particular variable by adding a validation block within the corresponding variable block.
