英文:

Terraform nested loop expression

问题

I'm trying to construct a collection to loop over based on nested data. The example below shows the code I am trying to use:

repos.tfvars
repositories = { workflows = { description = "Reusable workflow repository" topics = ["github-actions", "reusable-workflows"] }, aws-network-speciality = { description = "AWS Network Speciality study repository" topics = ["amazon-web-services", "aws", "terraform", "iac"] } }

main.tf

resource "github_repository_file" "tflint" { for_each = local.terraform_repos repository = each.key file = ".tflint" content = file("${path.module}/github_repository_files/.tflint") commit_message = "chore(managed-by-terraform): tflint configuration file" } ```

The desired outcome is that tflint is uploaded to each repository with the terraform topic.

Currently `local.terraform_repos` returns an empty map - I'm just unsure how to drill down into `var.repositories` to query the `topics[]` and then return the name of the repo(s) for the loop.

`contains` 应该用于 `topics`，而且您的参数有误。它应该如下所示：

terraform_repos = { for each, repo in var.repositories : each => repo if contains(repo.topics, "terraform")}

`contains` should be used for `topics` and also you have wrong arguments. It should be:

terraform_repos = { for each, repo in var.repositories : each => repo if contains(repo.topics, "terraform")}
