I often run `docker run hello-world` after setup as a basic check.
But I feel a bit boring.
So here's what I do instead:
docker run --rm -it warachet/hello-world
You get Matrix digital rain. Ctrl-C cleans up properly. hello-world (official) ~9-13 kB
warachet/hello-world ~4.4 kB multi-arch, ~2 kB single-arch
Not a serious work, just a fun thing to hack on and share.
