jjschwarz/buildah repository overview

⁠Buildah Environment

⁠Requirements

Requires Docker or Kubernetes in privledged mode

⁠Libraries Used

• Fedora 44
• Latest builds of buildah, podman, runc and qemu-user-static

⁠Notes

This images is used as a build kit for multi-architecture CI images with GitLab CI on Kubernetes. The image itself is build for AMD64 and ARM64 processors so that either system can be used to build Docker images for both platforms.

The container sets the STORAGE_DRIVER to vfs and the BUILDAH_FORMAT to docker for the buildah system. Due to gitlab requirements it uses iptables instead of nftables.

⁠Running container for debug

To run this container with kubectl for debug purposes use the command:

kubectl run -i  --privileged --rm --tty buildah-$$ --image=docker.io/jjschwarz/buildah --restart=Never -- sh
