I just start using my homelab to host some new good services, and I want to know what is the approach of a docker setup, what is the best distro for? How to deploy them correctly? Basically I’m a real noob in this subject. Thank you
Debian with the docker convenience script. Stay away from Ubuntu server, for the love of dog.
Make a folder such as /stacks and put everything there by building docker compose stacks. I bind mount everything local to a subfolder with the docker-compose.yml for that application so when I restore it, it’s all in one spot, not spread all over the hell like docker likes to do if you don’t use bind mounts.
Add lazydocker for getting easy log and stats access for each stack.
Avoid bare docker run commands. It makes an unmanageable mess when you get more that a couple containers running.
Consider using the nextcloud AIO master container. It runs docker containers inside a master container compose file, and it is by far the easiest way to manage and run nextcloud.
I’ve become very partial to Dozzle. I roll out right into my compose scripts and it’s incredibly lightweight.
I found dozzle a bit rudimentary as it only does logs, but I liked that there was an android app to interface it.
Lazydocker is more like Portainer on running stacks in that you can see logs, configs, stats and do operations on the stacks and components all from an SSH TUI.
I’ll have to check it out. TIL about the app.

They seem to be moving away from this, and it’s not longer the first option on their install page
On their debian page
Use a convenience script. Only recommended for testing and development environments
Also, it should be noted about the first option they recommend, Docker Desktop, that Docker Desktop is proprietary.
I recommend just getting the
docker.ioanddocker-composefrom debian’s repositories.What is so bad about Ubuntu server?
When I tried it last (a couple years ago), the docker snap was an untroubleshootable mess. I don’t like the idea of running Docker that way, in whatever version of a container that Canonical has come up with for snaps. It’s just looking for problems. Run an application with Snap if you want, but a whole container system? No thanks.
I just don’t use snaps and it works great for me. For docker I add their apt repository and install it like that.
I wrote a script to remove snaps and install Docker as per the docker website. Works great mate.
Plus you get the benefit of frequent updates.
One of their frequent updates completely broke docker on my system. Fortunately they did push the fix by the time I realized what happened.
Is that because you installed it via snaps instead of apt?
It was from docker’s apt repo, so a newer version than provided through Ubuntu’s channels I assume.
APT install is the same for Debian as it is for Ubuntu. Ubuntu delivers docker through APT or Snap but defaults snap.
I would start with a Debian os base, install docker and turn it into a swarm manager. Then look at stacks and how services work, if you find your running your host too hard. You can add a work host and stread out.
Once you have docker swarm running, get portainer running. I use portainer as a visual
whats happeningon my swarm, but I use the docker cli to start and update all my stacks. I have my stacks in a git repository so that I have a backup and history of what changes I did.Now your a docker master, of sorts.
Anything.
Personally I use Debian. But Docker doesn’t care. I chose Debian because it is very stable and simple
Yep, Debian and then add Portainer - for me this is the easiest setup to manage.
would prefer to not use portainer
