A trivial, simple example of how to use Buildah to build a Container Image.

buildah_ubuntu_neovim.sh

#!/usr/bin/env bash

container=$(buildah from docker.io/library/ubuntu)

buildah run ${container} -- sh -c "apt update && apt install --yes curl apt-transport-https ca-certificates"

buildah run ${container} -- sh -c "apt update && apt install --yes vim"

buildah config --entrypoint="/bin/bash" ${container}
buildah config --cmd="--login -i" ${container}

buildah commit ${container} localhost/ubuntu-vim:latest
