This should allow plans to succeed using the terraform_wrapper functionality whenever an exit code of 2 is returned.
https://www.terraform.io/docs/cli/commands/plan.html#detailed-exitcode

• This is useful for adding custom steps in our GitHub action workflows.

Disclaimer: Im not a Javascript developer so Im not sure how valid the OR condition is.

Hey @dannyibishev I am working on the same case as you now, but what I get from GitHub folks is, Actions itself only supports success (0 exit code) vs failure (anything else). So, it's not lack of support in Terraform Actions task, but general behavior of GitHub Actions.

Thanks @DariuszPorowski for the additional detail. We'll need to confirm what the best approach is here

We gone through a bit of song and dance here attempting to get apply job to run automatically if no changes to the plan.

      - name: Terraform Plan - https://www.terraform.io/docs/commands/plan.html
        id: plan
        run: terraform plan -detailed-exitcode -input=false -out=plan.out ${{ inputs.tf_plan_args}} ${{ secrets.tf_plan_secret_args }}
        continue-on-error: true

      - name: Check for Plan Failure
        if: steps.plan.outputs.exitcode == 1
        run: exit 1

      # Encrypt - Terraform plan.out

      - name: Encrypt Terraform "plan.out"
        if: steps.plan.outputs.exitcode == 2
        run: gpg --quiet --batch --yes --passphrase ${{ secrets.gpg_passphrase }} --symmetric --cipher-algo AES256 plan.out

      # Github - Upload Artifact
      # https://github.com/marketplace/actions/upload-a-build-artifact

      - name: Upload Encrypted Artifact
        if: steps.plan.outputs.exitcode == 2
        uses: actions/upload-artifact@v2
        with:
          name: ${{ inputs.tf_workspace }}-encrypted-plan
          path: ${{ inputs.working_dir }}/plan.out.gpg

    outputs:
      planExitcode: ${{ steps.plan.outputs.exitcode }}

  apply:
    name: "Terraform: apply"
    needs: plan
    if: needs.plan.outputs.planExitcode == 2
    runs-on: ubuntu-latest
    environment:
      name: ${{ inputs.github_env }}

The exit code stuff you guys are talking about gives us the annotation errors and is rather confusing to people.

@dannyibishev I've rebased your PR with latest changes so it will pass linting.

I changed the condition to exit early if it is 0 or 2 instead of setting the exit code to be more explicit with our returns. We'll tes this out and get it merged in the 2.1.0 release.

Hello,

With terraform-wrapper, we always have a response code 0 even if there is changes and option --detailled-exit-code.
Here is my testing workflow with a terraform plan and an echo $?.

We cannot return exitCode 2 with the wrapper because of setFailed function.

There is an opened issue for custom exit code.

Maybe, it will be better to add an environnement variable with status code for the wrapper.
