If you use .tfvars files across multiple configurations and expect to continue to see this warning, (Which is fine for my use case; not sure about others.). Teams that make extensive use of Terraform for infrastructure management often run Terraform in automation to ensure a consistent operating environment and to limit access to the various secrets and other sensitive information that Terraform configurations tend to require.. The best workaround I have found is by using putting something like this in override.tf. Sign in We should add validation that this isn't allowed. I don't want to accidentally have credentials setup for account A and be passing in the backend details for account B. } You just can't specify a distinct bucket for each workspace. http://bensnape.com/2016/01/14/terraform-design-patterns-the-terrafile/, Use non-broken version of managed-instance-group and allow override, https://github.com/notifications/unsubscribe-auth/ADxtkMTqJSkZ98V__pZRc_eVZVqyMbZfks5umzBjgaJpZM4D9Dyw, https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fhashicorp%2Fterraform%2Fissues%2F1439%23issuecomment-444504173&data=02%7C01%7Cgarin.kartes%40alaskaair.com%7C1692108d43a74281574e08d65abe4217%7C0f44c5d442b045c2bf55d0fea8430d33%7C1%7C0%7C636796170540379315&sdata=44aW3hZTTeccEDntjYPI03TeU11tqXtlJSKfJThwknk%3D&reserved=0, https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fnotifications%2Funsubscribe-auth%2FARwnyDDvgV-3yvBNCAQes2gsVqzbYiZNks5u19iXgaJpZM4D9Dyw&data=02%7C01%7Cgarin.kartes%40alaskaair.com%7C1692108d43a74281574e08d65abe4217%7C0f44c5d442b045c2bf55d0fea8430d33%7C1%7C0%7C636796170540389334&sdata=99pGIuhS1Td8MJQahoDjOJnsCWJGguO6x9amTi4BZco%3D&reserved=0, Feature Request : Module versioning for S3 source.

I don't want a backend file and tf vars for each environment. For convenience, Terraform defaults to interpreting -var and 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. 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. would merge map values instead of overriding them. when running terraform env select) it doesn't work.

Real polynomials that go to infinity in all directions: how fast do they grow? 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 app2: ../repo1/foo2.tf the module's own source code. I had the same error message when the first argument was also enclosed in [] (brackets), since it already was a list. 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. Can I ask for a refund or credit next year? to assign complex-typed values, like lists and maps. 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. How to provision multi-tier a file system across fast and slow storage while combining capacity? Do not hesitate to share your thoughts here to help others. You cannot use variables in variable files it will cause cyclic dependency. Please make the question in SO, as terraform should not be on SF. Hi @rosshettel. that value. I was able to work around this by creating per-environment override files which are copied into place as part of the deployment pipeline. The default if they are present: Files whose names end with .json are parsed instead as JSON objects, with Use pre-installed Terraform plugins instead of downloading them with terraform init. The following sections describe these options in more detail. Please vote for the answer that helped you in order to help others find out which is the most helpful answer. For org-name = "${local.orgname}" I'm going to keep this tagged with "thinking".

Thanks! } Reply to this email directly, view it on GitHub DB Safety feature and GCP opta destroy + config upload. GThoro 2 yr. ago Put t2.small in double quotes. 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. constructors. in your shell: For readability, and to avoid the need to worry about shell escaping, we Having such feature is particularly useful if you want to test new module version which is located in some feature branch in another (shared) repo, you then have to edit all paths to module manually and re-init anyways. I'd expect this to be a bit more verbose. How can I drop 15 V down to 3.7 V to drive a motor? Hands-on: Try the Simplify Terraform Configuration with Locals tutorial. My actual use case is: In every account I have a s3 bucket and dynamodb table that follows a specific naming convention. Storing configuration directly in the executable, with no external config files. It looks like: It seems it's not really possible to set nested key/value in the command line argument: backend "s3" { A backend block cannot refer to named values (like input variables, locals, or data source attributes). I agree with that statement. Because when I try doing the same like this: Create a file named backend.tfvars with content: Specify this file name in a command line option to the terraform command: 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. But otherwise they are very alike, but the first one fails, while the last one doesn't. Assume the below directory / file structure. Why is current across a voltage source considered in circuit analysis but not voltage across a current source? The example below checks whether the AMI ID has the correct syntax. 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. I was hoping to do the same thing as described in #13603 but the lack of interpolation in the terraform block prevents this. [Solved] Ruby on Rails 7 with esbuild generate multiples files .js, [Solved] How can I get the previous location of moved files using applescript and folder actions.

Obviously, quoting the value results in provider configuration not been passed properly into the module Have a question about this project? type of value that will be accepted as I see two things that could be causing the error you are seeing. You can specify custom validation rules for a particular variable by adding a validation block within the corresponding variable block. What is the etymology of the term space-time? 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? the caller may still use null in nested elements or attributes, as long as ####################### I overpaid the IRS. In the example above project1 might not even have staging and project2 might have unit/regression/load-testing/staging phases leading to production release. the calling module should pass values in the module block. Switching which infrastructure you're operating against could be as easy as checking out a different git branch. Can we please add var support in the terraform backend file. 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. Hands-on: Try the Protect Sensitive Input Variables tutorial. Type Constraints. It expected the id only and not the whole object. Setting a variable as sensitive prevents Terraform from showing its value in you spot this mistake. And how to capitalize on that? Assume that app1, app2 and foo1.tf all depend on foo2.

So the instance_count variable would also work using a string ("2") instead of a number (2).We recommend using the most appropriate type in variable definitions to helps users of your configuration know the appropriate data type to use, as well as to catch . 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. Are there any chances that we'll have this ability in future versions? Is it still waiting on the proposal mentioned in this comment, #4149 ? 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. When variables are declared in the root module of your configuration, they 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. We use GitHub issues for tracking bugs and enhancements, rather than for questions. This includes specifying where to find the Terraform configuration files, any extra arguments to pass to the terraform CLI, and any hooks to run before or after calling Terraform. But you should also create a variable.tf file also to define the variable type -. When may be expected if it IS on the roadmap. It makes for a mess at the top-level of the directory structure, and inconsistency in what you find inside each story-level dir structure. How to extract sensitive output variables in terraform? Making statements based on opinion; back them up with references or personal experience. You still cannot put variables in backend.conf, which was the initial question.

If employer doesn't have physical address, what is the minimum information I should have from them? Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. Terraform will still record sensitive values in the state, rev2023.4.17.43393. 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. } Should the alternative hypothesis always be the research hypothesis? +1. value must be convertible to the specified type. I want admins and automated-ci to be able to specify the local path, allow flexibility to pull from git or filesystem, etc, but this is not possible without allowing interpolation in the source param. Without having looked at the code, fixing such "small" issues might actually cascade into a massive amount of codebase rewrite, if hitting architectural limits. Can we get an answer as to why this is not supported? I got it by providing a list variable with following input: [name1,name2,name3] @umeat in that case you are right, it is not possible at the moment to use different backends for each environment. the collection or structure itself is not null. Instead I have to use the role_arn in the backend config which can't contain the interpolation I need. However, we discovered this behavior because running terraform init failed where it had once worked. Is that intended behavior? 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. There is an ongoing issue (#3116) which is currently open but @teamterraform seem to have made that private to contributors only. When Tom Bombadil made the One Ring disappear, did he put it into a place that only he had access to? on line 1: I need to be able to pass variable. +1, I understand why this may be architecturally tricky to get right, but it would be great to have on the admin/DRY side of things. Declare a variable as sensitive by setting the sensitive argument to true: Any expressions whose result depends on the sensitive variable will be treated Is there any documentation which could help folks get better acquainted with how this processing currently works?

Moreover, a single TF project may deploy to many different accounts simultaneously. Am I doing something wrong, or is it a bug with the Terraform / AWS Provider? }, ###################### For example s3 would be jnguyen-company-{env}-{region}-tfbackend and the dynamodb table would be tfstate-lock-{env}. and no special quoting for Terraform. Sensitive Resource Attributes. This would be a major design change to the underlying fundamentals of Terraform. You signed in with another tab or window. With a better understanding of the current difficulties/blockers, it would be easier to discuss potential solutions. This is a change from previous versions of Terraform, which This happens for resource types where Browse other questions tagged, Where developers & technologists share private knowledge with coworkers, Reach developers & technologists worldwide, This does not work, I still receive "variables not allowed here", I think this answer is incomplete as I still get, It should mention that you can't address a local in your tfvars, and should instead replace the variable with a local.something (at that point you could remove the local altogether). 4 years to fix such a small issue!? pretty ugly :-). env = "production" Connect and share knowledge within a single location that is structured and easy to search. @NickMetz it's trying to do multiple environments with multiple backend buckets, not a single backend. 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. That means they need to be provided when you run terraform init, not later when you use the backend with commands like terraform apply. Asking for help, clarification, or responding to other answers. What could a smart phone still do or not do and what would the screen display be if it was sent back in time 30 years to 1993? } That setup does have permissions issues but it is still possible. An example from https://stackoverflow.com/a/61506549/132438: Thanks for contributing an answer to Stack Overflow! @lorengordon I agree.. this is nonsense.. that and the fact that everytime you pull a whole repository instead of a leaf. 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. 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. Why don't objects get brighter when I reflect their light back at them? You are receiving this because you commented. or .tfvars.json) and then specify that file on the command line with I had the same issue, but my problem was the missing quotes around default value of the variable. I found no way to prevent accidental deletion of an Elastic Beanstalk Application Environment. The same with wrapper. While I can understand the reasons for not supporting general var/local inclusion .. $ terraform plan -var 'compartment_id=abcd.1234'. Changing module versions manually is error prone. 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).
