Containers are just processes with flags. Those flags isolate the process’s filesystem, memory [1], etc.

The advantages of containers is that the software dependencies can be unique per container and not conflict with others. There are no significant disadvantages.

Without containers, if software A has the same dependency as software B but need different versions of that dependency, you’ll have issues.

[1] These all depend on how the containers are configured. These are not hard isolation but better than just running on the bare OS.

It sounds like your port forwarding settings weren’t saved and the reboot has gone back to a previous configuration.
