Docker compose plus using external volume mounts or using the docker volume + tar backup method is superior

Yeah, when I got started I initially put everything in Docker because that's what I was recommended to do, but after a couple years I moved everything out again because of the increased complexity, especially in terms of the networking, and that you now have to deal with the way Docker does things, and I'm not getting anything out of it that would make up for that.

When I moved it out back then I was running Gentoo on my servers, by now it's NixOS because of the declarative service configuration, which shines especially in a server environment. If you want easy service setup, like people usually say they like about Docker, I think it's definitely worth a try. It can be as simple as "services.foo.enable = true".

(To be fair NixOS has complexity too, but most of it is in learning how the configuration language which builds your operating system works, and not in the actual system itself, which is mostly standard except for the store. A NixOS service module generates a normal systemd service + potentially other files in the file system.)

I like reminding people that with every new technology, the old one is still around. The new gets most of the attention, but the old is still kicking. (We still have wire wrapped programs kicking around.)

You are all good. Spend your limited attention on other things.

I don’t like docker. It’s hard to update containers, hard to modify specific settings, hard to configure network settings, just overall for me I’ve had a bad experience. It’s fantastic for quickly spinning things up but for long term usecase and customizing it to work well with all my services, I find it lacking.

I just create Debian containers or VMs for my different services using Proxmox. I have full control over all settings that I didn’t have in docker.

I used docker for my homeserver for several years, but managing everything with a single docker compose file that I edit over SSH became too tiring, so I moved to kubernetes using k3s. Painless setup, and far easier to control and monitor remotely. The learning curve is there, but I already use kubernetes at work. It's way easier to setup routing and storage with k3s than juggling volumes was with docker, for starters.
