Hello, have setup my proxmox server since some weeks recently I found that LXC containers could be useful as it really separate all my services in differents containers. Since then I figured out to move my docker’s services from a vm into several LXC containers. I ran into some issues, the first one is that a lot of projects run smoother in docker and doesn’t really have a “normal” way of being package… The second thing is related to the first one, since they are not really well implemented into the OS how can I make the updates?
So I wonder how people are deploying their stuffs on LXC proxmox’s containers?
Thanks for your help!
EDIT : Tried to install docker upon debian LXC but the performances were absolutely terrible…
In general, I prefer unprivileged LXC to a full VM unless there’s some specific requirement that countermands that preference (like running an appliance or a non-Linux OS).
What I tend to do is create a new container for each service (unless there’s a related stack). If the service runs on Docker, I’ll install that right inside the container and manage it with
docker compose. By installing Docker directly from get.docker.com instead of the built in packages, it pretty much works all the time.Since each service is in its own container, restoring backups is pretty service-specific. If you wanted some kind of central control plane for docker, you could check out swarm mode.
I tried to install docker with the get.docker link but the same results occurs I got really bad performance… So I wonder how to self host stuffs when using LXC containers and install services the old school way
That will be totally doable, but there’s no one way to setup every service. Some you’ll install from the repository (like nginx or HAProxy or samba). Others you’d have to clone from git (like netbox or dokuwiki). Others have entirely different methods. So, unfortunately it’ll be a lot of reading the documentation.
