• When running in interactive mode, pressing Ctrl+C doesn't cleanly exit. For now, run it in detached mode (-d). Calling docker stop cleanly exits though.

• s6 supervision suite, similar to runit and daemontools
• s6-overlay, base container with s6 and alpine
• docker-slim, a tool to automatically analyze and trim existing fat containers
