terraform variables may not be used hereshrimp toast recipe david chang

4 years to fix such a small issue!? module configuration blocks, and cannot be At the moment we use multiple environments prod/stage and want to upload tfstate files to S3. Variables may not be used here I'm trying to combine variables into other variables. Thanks for contributing an answer to Stack Overflow! Reply to this email directly, view it on GitHub environment variables (set by the shell where Terraform runs) and expression rev2023.4.17.43393. Hi, Near the bottom of the file, find the aws_db_instance.database block that defines your database. 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. } Sign in Why does Paul interchange the armour in Ephesians 6 and 1 Thessalonians 5? It would be nice if I could have a variable file that specifies stack_name, environment, region. Agreed, issue has been open since 2017 ? +1 for this. peer-cidr = "192.10.0.0/16" Also I appreciate this is one resource duplicated, and it would be much worse elsewhere for larger configurations. Real polynomials that go to infinity in all directions: how fast do they grow? 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. This is a change from previous versions of Terraform, which For example s3 would be jnguyen-company-{env}-{region}-tfbackend and the dynamodb table would be tfstate-lock-{env}. It would be more comfortable to have a backend mapping for all environments what is not implemented yet. a variable definitions file (with a filename ending in either .tfvars argument requires a literal value and cannot reference other objects in the Said another way, TF as it is right now gives me a lot of compile time and runtime errors. 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. Is there any sort of solution besides upgrade to 0.15? You might also check out these adjacent issues: or .tfvars.json) and then specify that file on the command line with And how to capitalize on that? 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. Sign in When variable values are provided in a variable definitions file, you can use +1. If this gets closed then those following cant view the issue. I want to use ${terraform.workspace} variable in terraform scope. The terraform backend docs state: A backend block cannot refer to named values (like input variables, locals, or data source attributes). 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. I also would like to be able to use interpolation in my backend config, using v 0.9.4, confirming this frustrating point still exists. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. when its expecting: ["name1","name2","name3"]. may assign the value null to the variable. Sci-fi episode where children were actually adults. Making statements based on opinion; back them up with references or personal experience. The database username and password are hard-coded. Please help! Personally I'd love to see interpolation for the entire source parameter. Ideally it'd be set up so everything named "project-name-master" would have different permissions that prevented any old dev from applying to it. ^This. Already on GitHub? This helps our maintainers find and focus on the active issues. Outlook needs password but dialog box disappears, Known HDD user password not working on new Bios. if you need help, let me know. value definition. Some special rules apply to the -var command line option and to environment This feature was introduced in Terraform v0.14.0. It would be nice to understand why this can't work. so while I'm bummed that this doesn't work, I understand that I shouldn't expect it to. It was requested by so many people! @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. pretty ugly :-). Why hasn't the Attorney General investigated Justice Thomas? Am not sure I understood the solution. 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. @lorengordon I agree.. this is nonsense.. that and the fact that everytime you pull a whole repository instead of a leaf. I can't share the script that copies the files, but it uses the find command to find any override files under a certain path and the exec flag to copy them to the desired path. If both the type and default arguments are specified, the given default followed by the name of a declared variable. value must be convertible to the specified type. Thanks for posting this issue, without it, it would of taken me a long time to figure out whats going on. Deploying your terraform to a different account, but using the same backend bucket. from the perspective of the user of the module rather than its maintainer. It also shifts a lot of potential errors away from a compile-time error to a runtime error, which we've wanted to avoid. FIX: rename variables.tf to variables.tfvars. default value, then Terraform uses the default when a module input argument is null. I got it by providing a list variable with following input: [name1,name2,name3] This functionality allows you to share modules across different Connect and share knowledge within a single location that is structured and easy to search. If you have defined a variable value, but not its corresponding variable {} For example, at a bash prompt on a Unix system: On operating systems where environment variable names are case-sensitive, Which in the output will generate us a main.tf file with an injected access_token and fire off terraform init as a child process. I had this error on Terraform when trying to pass a list into the module including my Data source: The given value is not suitable for module. Does it have to be placed here so that I don't have to check the access and secret keys to github, terraform { I believe the blocker is that to support this feature one would need to implement pre-processing of the configuration. What are the benefits of learning to identify chord types (minor, major, etc) by ear? set lifecycle to prevent destroying anything marked as production. 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. declare an attribute as sensitive, source = "./iam/customer/${local.orgname}" The text was updated successfully, but these errors were encountered: So the underlying issue is that I forgot to quote the value. @MichaelDeCorte It's just that it's possible to override the module source parameters with an external file. In my example you could still use terraform environments to prefix the state file object name, but you get to specify different buckets for the backend. Linux or macOS. the collection or structure itself is not null. terraform. That's a lot of wet, brittle code that won't stand up to any significant change in the repository structure. Check the terraform version. See here: https://terragrunt.gruntwork.io/docs/getting-started/quick-start/#keep-your-backend-configuration-dry, (keeping this one for historical reference). We conclude the difference as that the variables.tf just declare valid variables and optionally their types, and the tfvars file assigns them values. Find centralized, trusted content and collaborate around the technologies you use most. You are receiving this because you commented. From: josephcaxton Not impossible, but not something that is likely to happen without a major product design effort. app1: repo1/foo2.tf privacy statement. The connections between resources and their providers happens too early for Terraform to be able to evaluate expressions in that context, because the provider must be known in order to understand the other contents of the block. Variables are not available in this scope? value = var.aad_allowed_tenants[0] terraform plan error "features": required field is not set, can't declare map variables in child modules in terraform 0.12, Terraform variables not applied from command line, Terraform getting error when configuring S3 Backend. Sign in And one dynamo table will suffice for all workspaces. values behave the same way as other variables: the last value found overrides rev2023.4.17.43393. Sensitive Data in State. may treat the entire block as redacted. features {} literal expressions It may not display this or other websites correctly. A provider error could disclose a value if that value is included in the error message. That means they need to be provided when you run terraform init, not later when you use the backend with commands like terraform apply. Thanks for contributing an answer to Stack Overflow! Thanks again for the feedback! 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! privacy statement. FIX: rename variables.tf to variables.tfvars 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. We were able to get around this by using backend-config when initializing the Terraform project as shown below. 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 environment of its own process for environment variables named TF_VAR_ Funny thing is when I do it with another variable, that has the same structure, I don't get this error. My use-case was inside a module that uses the Github provider. 29: } The given value is not valid for variable "instance_config": list of map of string required. different variables. region = "us-east-1" This is just a reminder to please avoid "+1" comments, and to use the upvote mechanism (click or add the emoji to the original post) to indicate your support for this issue. Though it's fairly reasonable to want to store the state of an environment in the same account that it's deployed to. providers = { as sensitive themselves, and so in the above example the two arguments of the main.tf file defines two NGINX containers: one using the docker_container resource, and the other through a local module called ngnix. If your .tfvars file is in another directory you must provide it as a -var-file parameter. Here is an example of a test .tfvars file environment_name = "sandbox" location = "eastus" resource_group_name = "rg-$ {var.environment_name}-$ {var.location}-001" and the associated variables.tf variable "location" {} variable "environment_name" {} I am asking this question WHY? peer-account = "xxxxxxxxxxxxxx" If I could store the git URL and a ref tag somewhere in tfvars, for example, that would meet my needs. As environment variables. 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). to your account, https://gist.github.com/steinybot/6d6fed5c27d7eb919a1c939521d57c20. You get around that by using terraform init -backend-config so that value is known at the beginning of the lifecycle. When using the -var parameter, you should ensure that what you are passing into it will be properly interpreted by HCL. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. If you use a sensitive value as part of an watch out for the types. seems my local test env was still running on terraform 0.9.1, after updating to latest version 0.9.2 it was working for me. A sensitive variable is a configuration-centered concept, and values are sent to providers without any obfuscation. 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. why not use some simple shell script with variable substitution instead?
