[QUESTION] How can I use a buildah script for image generation using GitHub Actions?

[divyansh42]

If your use case is satisfied by this action, you can use this action to build image and push-to-registry action to push to Github Container Registry (or registry of your choice).
With this action you can also build image without dockerfile. Check this.

But, if you still want to build image typically using shell you can do something like this in your workflow:

- name: Test Build
  run: | 
    #!/bin/sh
    ctr=$(buildah from alpine:3)
    buildah commit "$ctr" my-alpine-image

As Github Linux runners comes with buildah pre-installed https://github.com/actions/virtual-environments/blob/main/images/linux/Ubuntu2004-README.md#installed-software

Is this what you wanted to ask? or something else?
