Docker vs Buildah
Docker is a perfect tool but there is one problem, docker relies heavily on Docker engine which is a docker daemon that runs in the background! What if this engine fails, all our containers would be stopped?
Buildah to rescue - https://minimaldevops.com/buildah-and-docker-are-both-tools-for-building-container-images-but-they-have-some-key-differences-a3530b923be0
There are also many other container runtime like Podman, ContainerD, CRI-O
