Hi,

For Docker, there are a number of GitHub Actions with good documentation that can be used
to build containers, and push them to registries using docker build/buildx.

I've started using these Actions:

https://github.com/docker/setup-buildx-action/
https://github.com/docker/docker-login-action/
https://github.com/docker/build-push-action
https://github.com/docker/metadata-action

docs:
https://docs.github.com/en/actions/publishing-packages/publishing-docker-images

These docs and actions are actually quite good when setting up
automation in GitHub for building/pushing containers.

Are there equivalent GitHub Actions for using podman?

I still think that podman/buildah are overall better tools for building containers
than Docker.
