Bocker: Docker implemented in around 100 lines of Bash (2015)

Makes me wonder why docker still didn't make it to the ubuntu/debian repositories. Would be such an easy net benefit

(a) Docker wants to bundle vendor libraries instead of using other packages and (b) Canonical uses LXD and MicroK8s instead.

What do you mean? It's been there for years: https://packages.debian.org/docker.io

It’s an old version, and I think it isn’t supported by Docker Inc (for the reasons mentioned in the sibling comment), but it’s there.

Damn good to know! Have been gaslit by the ever-changing docker install instructions. Of course it would be a lagging version, but I think the docker feature-set has converged years ago, why would I care any more about the docker version than e.g. about the version of grep?

The buildx/build and docker-compose vs 'docker compose' are recent updates.
