# terraform-validate

Validate Terraform configuration files using the official Terraform CLI.

## Inputs

| Input | Required | Default | Description |
|-------|----------|---------|-------------|
| `terraform-dir` | No | `terraform` | Directory containing `.tf` files |
| `terraform-version` | No | `~1.15` | Terraform version to use |
| `workspace` | No | `""` | Terraform workspace to use |
| `jfrog-token` | No | `""` | JFrog Artifactory token for the Terraform provider registry (`TF_TOKEN_schmalz_jfrog_io`) |
| `mock-files` | No | `""` | Newline-separated list of file paths (relative to repo root) to create as empty files before validation. Useful when Terraform uses `file()` references that do not exist in CI. |

## Usage

```yaml
- uses: https://schmalz-git.git.onstackit.cloud/schmalz/shared-actions/terraform-validate@terraform-validate-v1
  with:
    workspace: stage
    jfrog-token: ${{ secrets.JFROG_TOKEN }}
```

With mock files for `file()` dependencies:

```yaml
- uses: https://schmalz-git.git.onstackit.cloud/schmalz/shared-actions/terraform-validate@terraform-validate-v1
  with:
    workspace: stage
    jfrog-token: ${{ secrets.JFROG_TOKEN }}
    mock-files: |
      config/app.json
      secrets/tls.crt
      secrets/tls.key
```

## Notes

- Runs `terraform init -backend=false`, `terraform fmt -check -recursive`, and `terraform validate`.
- Sets `TF_WORKSPACE` during validate if `workspace` is provided.
- Sets `TF_TOKEN_schmalz_jfrog_io` on both `init` and `validate` steps if `jfrog-token` is provided.
- When `mock-files` is set, empty files are created at the given paths (including any missing parent directories) before `terraform init` runs. This allows validation of configurations that reference external files via `file()`.
