Ability to use latest Terraform version rather than hard coding tf_actions_version

[Eddie Stecker]

Hello,
Before v0.5.0 you had to update the Terraform version in these actions. Now the end user needs to update the Terraform version. Is it possible to add a feature to just use latest Terraform version? We are using Terraform Cloud with workspaces set to "latest" version. It's difficult to time a change to "tf_actions_version", in a large amount of repositories, with the Terraform releases.

Thanks

Hi @EddieOX

It's only FYI.

• Short answer is No.

see: https://github.com/hashicorp/terraform-github-actions/blob/master/src/main.sh#L47
"latest" directory is none on releases.hashicorp.com/terraform/

maybe can use hashicorp/terraform:latest image. tfenv, or others.
but now so not...

• Alt answer is Yes.

Of course I have many projects, repositories and versions.
I think don't wrote "tf_actions_version" literal some times too.
So I try to sometimes...

see:

name: pr_tf
on:
  pull_request:
env:
  TF_ACTIONS_VERSION:    0.12.13
jobs:
  on-pull-request:
    name: terraform
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@master
    - name: Terraform - Format
      uses: hashicorp/terraform-github-actions@master
      with:
        tf_actions_version:     ${{ env.TF_ACTIONS_VERSION }}
        tf_actions_subcommand: 'fmt'

    - name: Terraform - Init
      uses: hashicorp/terraform-github-actions@master
      with:
        tf_actions_version:     ${{ env.TF_ACTIONS_VERSION }}
        tf_actions_subcommand: 'init'

ommit

so looks env use re-cycle workflow.yaml.
Write only one time.
nnnn, It's not cool?... 😢

• other answer use secrets.

      with:
        tf_actions_version:     ${{ secrets.TF_ACTIONS_VERSION }}

perhaps if all tf directory only one version in repository, maybe cool.

• Great answer

maybe great answer is fix action.yml.
here not require and default version set.

BTW. I think "tf_actions_subcommand" 's default value is "fmt" is good.
It's zero configurations is good.

That's ALL.

This is what I came up with to solve my problem:

name: 'Terraform Pull Request Workflow'
on:
  - pull_request
jobs:
  main:
    name: 'Terraform Actions'
    timeout-minutes: 3
    runs-on: ubuntu-latest
    steps:
      - name: 'Get latest Terraform GitHub release and remove "v" from tag name for version'
        run: "echo ::set-output name=tf_actions_version::$(curl -s https://api.github.com/repos/hashicorp/terraform/releases/latest | jq -r '.tag_name' | sed 's/^v//')"
        shell: bash
        id: get_tf_latest
      - name: 'GitHub Checkout'
        uses: actions/checkout@master
      - name: 'Fmt Check'
        uses: hashicorp/terraform-github-actions@master
        with:
          tf_actions_version: ${{ steps.get_tf_latest.outputs.tf_actions_version }}
          tf_actions_subcommand: 'fmt'
          tf_actions_working_dir: '.'
          tf_actions_comment: true
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
