.terraspace-cache folder doesn't contain the module template file

[pie-r]

terraspace version:

bundle exec terraspace version
0.6.13

I have a module like this, with a test_ssh folder and a .tpl file on it:

  infra
   ├── app
    │   ├── modules
    │   │   └── ec2
    │   │       ├── ec2.tf
    │   │       ├── iam.tf
    │   │       ├── output.tf
    │   │       ├── test_ssh
    │   │       │   └── user_data.tpl. --> this file is missing in .terraspace-cache
    │   │       ├── variables.tf
    │   │       └── versions.tf

But in the .terraspace-cache folder there isn't the template file after the plan:

└── infra
    ├── .gitignore
    ├── .terraspace-cache
    │   └── eu-central-1
    │       └── sandbox
    │           ├── modules
    │           │   └── ec2
    │           │       ├── ec2.tf
    │           │       ├── iam.tf
    │           │       ├── output.tf
    │           │       ├── variables.tf
    │           │       └── versions.tf

In Fact, I tried with:

resource "null_resource" "temporary" {
  triggers = {
    path = "${path.module}/test_ssh/user_data.tpl",
    path1 = "${path.cwd}/test_ssh/user_data.tpl",
    path2 = "${path.root}/test_ssh/user_data.tpl"
  }

}

The plan is:

  # module.ec2-mice-instance.null_resource.temporary will be created
  + resource "null_resource" "temporary" {
      + id       = (known after apply)
      + triggers = {
          + "path"  = "../../modules/ec2/test_ssh/user_data.tpl"
          + "path1" = "/Users/xxx/projects/git/terraform-services/terraspace/infra/.terraspace-cache/eu-central-1/sandbox/stacks/mice-service/test_ssh/user_data.tpl"
          + "path2" = "./test_ssh/user_data.tpl"
        }
    }

The template example I'm working on is:

data "template_file" "test_user_data" {
  # No way to fix it
  template = file("${path.module}/test_ssh/user_data.tpl")
}

If I use ${path.module} I get:

│ Error: Invalid function argument
│ 
│   on ../../modules/ec2/ec2.tf line 3, in data "template_file" "test_user_data":
│    3:   template = file("${path.module}/test_ssh/user_data.tpl")
│     ├────────────────
│     │ path.module is "../../modules/ec2"
│ 
│ Invalid value for "path" parameter: no file exists at
│ ../../modules/ec2/test_ssh/user_data.tpl; this function works only with
│ files that are distributed as part of the configuration source code, so if
│ this file will be created by a resource in this configuration you must
│ instead obtain this result from an attribute of that resource.

With the full original path ("/Users/xxx/projects/git/terraform-services/terraspace/infra/.terraspace-cache/eu-central-1/sandbox/stacks/mice-service/test_ssh/user_data.tpl") outside the .terraspace-cache folder, it works.

This might be because terraspace cleans up the .terraspace-cache folder between commands. You can turn off this behavior with build.clean_cache = false

config/app.rb

Terraspace.configure do |config|
  ...
  config.build.clean_cache = false
end

• App Config: https://terraspace.cloud/docs/config/app/
• Reference: https://terraspace.cloud/docs/config/reference/

Thinking that may be it. Am considering changing the default from true to false.

Hi, no I already tested this flag without a good effect. I found this flag from another issue but in this case it doesn't fix the problem. I'd like to contribute if you can put me in the right path.

OT: I'm comparing terraspace and terragrunt in 4 articles, the next one will be terraspace, are you interested to review it before the release?

Figured out what's going on. The builder was checking for any path with the word test in it. The test_ssh folder was being skipped. Fixed #142 and released in 0.6.17

Very cool! Can read it after its published. Hope it's good. Good luck with the article! 🎉
