There are teachings I have read/ discovered through YouTube (can't remember exactly where) about the reasons and the philosophy behind moving to docker, or having it as a state machine.

Have you considered looking into dockers alternatives, also ?

Here is 1 of the sources that may give you insights:

-- There has been some concerns over docker's licensing and, as such, some people have started preferring solutions such as podman and containerd.

Both are good in terms of compatibility and usability, however I have not used them extensively.

Nonetheless, I am currently using docker for my own hyperserver [Edit2: oops, I meant hypervisor ✓, not hyperserver] purposes. And I am also a little concerned about the future of docker, and would consider changing sometime in the future.

[Edit1: I am using docker because it is easy to make custom machines, with all files configurations, and deploy them that way. It is a time saver. But performance wise, I would not recommend it for major machines that contain major machine processes and services. And that's just the gist of it].
