Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

In your scenario I don't think I'd use Proxmox as you're going to run into issues with lack of RAM. I think you're going to have issues running out of memory either way though. Running the whole machine as a Docker node would probably be more memory-efficient than having the overhead of running separate VMs under Proxmox.
NGINX should run fine as a container. There's even an official build available on Docker Hub.
I think you should be able to run containers directly on Proxmox, and have enough RAM to run one VM for the thing that can't be containerized.
That is also a fine approach, didn’t think of that. I never worked with Proxmox, and had no idea i can run containers directly on it. How would restoring a container work in that case?
Example, i purchase another machine, install fresh proxmox on it, can i simply restore the containers from the original machine without any additional configuration?
The containers in Proxmox (LXC Containers) are a little different from Docker containers. You can't deploy Docker containers directly as LXC containers. You can, however, run an LXC container and install Docker on it, then run Docker containers there.
