Ah, I see, thank you. Sounds like just manually starting docker-compose stuff will be preferable right now.

I'd make systemd unit files around the docker-compose deployments. Upload everything with something like Ansible. If you want to go perfect go for NixOS instead, but that might be controversial.

Doesn't Compose take care of that with "restart: always"? Though that probably doesn't work on reboot...

It does!

"restart: always" and "restart: unless-stopped" both work fine after reboot on my system. (Although Docker recommends managing it using systemd or upstart if you want more granular control).

https://docs.docker.com/config/containers/start-containers-a...

This is for Docker, right? Not Compose? Though I guess Compose would just set the flag in Docker, in which case it'd do the same thing. I don't want more granularity than "unless stopped", basically, so this is ideal, thanks!

Docker-compose is just a wrapper by itself. It just make volumes, port forwarding, etc based what you you will describe in your docker-compose file.

So if you have proper Docker installation, containers will restart on reboot.

I think the main question is: do you need orchestration? Ie scheduling workloads dynamically to different machines. If yes, then ks/Nomad/Swarm. If no and you want minimal overhead then the above is the answer.

I’d also suggest Podman as a Docker alternative, especially for these scenarios. Images and Dockerfiles (and many commands) are 1-to-1 compatible but there are some nice things especially with this scenario.

I wouldn’t say NixOS is controversial, at all, but it’s a very steep learning curve.

Docker compose is certainly enough for personal use, but if you ever want your apps to be available during update process (on docker compose you'll have to shut down your app container before you can update it), it's very easy to setup a basic blue/green deployment using the readiness probe option in kubernetes.

Also, kubernetes load balancer is pretty easy to setup and plays well with multiple services and letsencrypt. On docker compose, I'll have to either use nginx and update it everytime I add more apps or use something like traefik if I want a load balancer that can read configuration from app's label. On kubernetes you simply specify several lines of ingress definition in your yaml file, which is not too complex for a typical app.
