I've only read the first chapter, which is the general presentation of Docker, and it's awful. First of all, it's very long, with many words and a very low ratio of signal to noise.
Many texts look like they were copied from a Docker commercial. For instance the mention of Docker Swarm won't mean anything to someone that doesn't already know Swarm. And there's no distinction of main components against optional components like Swarm.
The final comparison to other container systems is pure junk. It should at least mention when the containers are compatible (like Podman) or not (like LXC).
I'm sorry for the harsh words. I wondered if I should keep silent or prevent other people from wasting their time with this. The low quality had me annoyed enough to opt for the latter.
