Buildah – build your containers from the ground up

Tools like buildah and cri-o really give us some hope on the backend. I want rock solid components that do one thing well and fail in predictable ways.

Just had a play with this on a VM.

Really not much of a challenge to adjust to from docker. The posix style CLI args are quite similar as is the stdout.

This was enough to get me into a container:

    debcontainer=$(buildah from debian)
    buildah run $debcontainer /bin/bash

    root@61badeb3d050:/# uname -r
    4.10.15-200.fc25.x86_64
