It probably has its advantages but until the UX reaches what we get with “docker run” this technology will never achieve its potential. When developing we need to think not only about what is possible but also how people do things currently and how does that compare to what we are proposing in terms of ergonomics. How many commands to get from 0 to hero with incumbent solution? How many with proposed solution? You get the point.
Better to use podman and build your own containers from Containerfile/Dockerfile (your own or open source ones, there are a ton on GitHub/GitLab/Codeberg that you can build yourself) and base layers.
That's not "broken". Docker Inc. is just rate-limiting access to their service. A service which, for what it's worth, has been used to bootstrap the technology required to sustain a pile of money for a lot of people.
There are other container repositories, and as you said, you can build your own containers and run those.
I personally really like Bastille for jail management. It's way more ergonomic than creating jails by hand and allows you to focus on the stuff running in the jails rather than the jails themselves.
I believe FreeBSD has podman running on top of jails now, so that should... exist? I mean, you can still run jails directly like this, but the days of `podman run` are either here or imminent.
