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.

Docker Desktop on Mac is a handicapped, underprivileged mess. Docker cli for Mac with Colima is still underprivileged, but at least you can skip the bs license and Docker's gui. On Windows you can at least use Docker on WSL which works great. Why use Docker Desktop is beyond me.
