What channel is most appropriate to post a question about Pulumi's GitHub Actions (pulumi/actions@v4)?

I think here is fine.

We would like to incorporate the Pulumi Actions into our CI/CD workflow. I looked through the examples but could not find a way set a variable for our "stack-name". We would like to use GitHub Environments to help trigger deployments with Pulumi. Right now the only way I can get our action to work is by hardcoding a stack-name.

- uses: pulumi/actions@v4
        with:
          work-dir: fargate/infra
          command: preview
          stack-name: acmecorp/mystack/dev

You can use a regular Github Actions variable to make the stack name dynamic. There’s no special Pulumi support required. It would look something like this:

stack-name: ${{ env.stack }}

Thank you.

or use inputs, those are basic mechanisms of github actions
