Where can I learn Docker fundamentals? (lemm.ee)

I jumped into Docker feet first a few months ago and have not had a real good time with it. Networking doesn't make sense, I can't ever seem to access config files without dropping to su -, all the tutorials and videos I find are pretty top level and assume the user already has a firm grasp on it. It's great for drop in stuff like open speed test and Vaultwarden but I recently tried setting up dashy and I can't even find the config files to edit. The Dashy documentation says the easiest way to edit the configs is to use code-server, so I spun up a code-server VM and can't even get it to open the files because the web based VSC doesn't allow for SSH editing. There's nothing explained in the documentation beyond that.

Yes I'm frustrated but I'm not bitching as if these solutions are trash, I'm simply asking where can I go to learn this shit from the ground up? It doesn't make any sense to me from the perspective that I've approached it. Networking seems to be silly and weird, entering an interactive TTY to the container seems to be useless as there's no package manager and doesn't seem to have vim, nano, or any native way to edit configs. It's been extremely frustrating so I ask you, where can I learn what I'm doing wrong and how to properly work with Docker?

Some pointers that might help you:

You can mount the same directory in multiple containers. So you can totally have a container reading files from a directory, and access the same files on that directory from, say, a VSCode server container. Just make sure the containers both use the same UID and GID to prevent permission issues.
