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

The fact how simple it is to re-implement a large part of Docker because all it fundamentally is a bit of glue code to the kernel is the biggest problem Docker-the-company faced and still faces.

Where Docker adds real value is not (just) Docker Hub but Docker for Windows and Mac. The integrations offer a vastly superior experience than messing around with VirtualBox and Vagrant by hand (been there, done that) to achieve running Docker on one's development machine.

Nah, they should have prioritized building some sort of PaaS solution like CloudRun, Render or Fly so they can sell that to enterprises for $$$. Instead they did half-baked docker swarm which never really worked reliably and then lost ground to k8s rapidly

Didn’t they buy at least one of these? It was garbage, and no one cared.
