Podman arch types

podman build -f Containerfile . --arch=amd64 Set the architecture of the image to be built, and that of the base image to be pulled, if the build uses one, to the provided value instead of using the architecture of the build host. Unless overridden, subsequent lookups of the same image in the local storage matches this architecture, regardless of the host. (Examples: arm, arm64, 386, amd64, ppc64le, s390x)

Push to both Gitlab and Github

git remote

git remote add github https://github.com/arslankhanali/demo_multiarch.git
git push -u github main
