How to leverage plan -out and apply

[yordis]

Hey there, I am a bit confused about how I could set up the terraform plan -out and terraform apply [file name]

It may be beneficial to showcase some examples demonstrating how it could be accomplished.

I thought it would be trivial, but I haven't been able to make it work with artifacts or however I suppose to make it work.

Here is what I got so far:

env:
  tf_working_dir: home/infrastructure/github/testing-project

jobs:
  terraform:
    name: Terraform
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v2.5.0

      - name: Get Terraform Version
        uses: straw-hat-team/github-actions-workflows/asdf/get-version@v1.5.1
        id: terraform-version
        with:
          plugin-name: terraform

      - name: Setup Terraform
        uses: hashicorp/setup-terraform@v2.0.3
        with:
          terraform_version: ${{ steps.terraform-version.outputs.plugin-version }}
          terraform_wrapper: true

      - name: Terraform Format
        if: github.ref != 'refs/heads/master' && github.event_name == 'pull_request'
        run: terraform fmt -check
        working-directory: ${{ env.tf_working_dir }}

      - name: Terraform Init
        run: terraform init -backend=true
        working-directory: ${{ env.tf_working_dir }}

      - name: Terraform Validate
        if: github.ref != 'refs/heads/master' && github.event_name == 'pull_request'
        run: terraform validate
        working-directory: ${{ env.tf_working_dir }}

      - name: Terraform Plan
        if: github.ref != 'refs/heads/master' && github.event_name == 'pull_request'
        run: terraform plan -input=false -out=${{ github.sha }}.tfplan
        working-directory: ${{ env.tf_working_dir }}

      - name: Upload terraform Plan Artifact
        if: github.ref != 'refs/heads/master' && github.event_name == 'pull_request'
        uses: actions/upload-artifact@v3.1.1
        with:
          name: terraform-plan-${{ github.sha }}
          path: ${{ env.tf_working_dir }}/${{ github.sha }}.tfplan
          if-no-files-found: error

      - name: Download terraform Plan Artifact
        uses: actions/download-artifact@v3.0.1
        if: github.ref == 'refs/heads/master' && github.event_name == 'push'
        with:
          name: terraform-plan-${{ github.sha }}
          path: ${{ env.tf_working_dir }}/${{ github.sha }}.tfplan

      - name: terraform Apply
        if: github.ref == 'refs/heads/master' && github.event_name == 'push'
        run: terraform apply -auto-approve -input=false ${{ github.sha }}.tfplan
        working-directory: ${{ env.tf_working_dir }}

I am not sure what is going with github.sha but it changes by the time it gets into master so the artifact is not found. Maybe you know what I am doing wrong or what I should be doing.

Thanks in advanced.

Hi @yordis 👋 Thank you for raising this and sorry you are running into trouble here. Please note that this GitHub repository's issue tracker is only used for feature requests and bug reports for the setup-terraform GitHub action itself. Since this appears to be a GitHub Actions workflow question, my best recommendation would be to submit a topic in the Terraform section of HashiCorp Discuss or Actions section of GitHub Community Discussions, where there are many more people asking and answering usage questions such as these.
