Docker integration

[Populus]

Greetings.
I wanted to make the suggestion that Docker containers show up in the tree view of the datacenter view in Proxmox VE.
Datacenter -> Node -> VM/LXC -> Docker container(s).

The reason for it is because it is annoying that some Proxmox containers contain several Docker containers and there is no 'quick-glance' to see what's running what.

It would be a Q.O.L improvement.

We do not support Docker containers on top of LXC containers. If you want to use a Docker container, you should do so in a VM. Hence, we probably won't add such a feature any time soon as it would just encourage a use case we want to avoid.

Maybe you could try running the 'Pulse' monitoring application, it can be run in an LXC container and provides an 'at a glance' wealth information about the Proxmox environment, with docker and proxmox backup etc.

Installation script is available here: https://community-scripts.github.io/ProxmoxVE/scripts?id=pulse

Okay, I see. The main culprit of my scenario is a VM actually, does that mean you'll look into it?

May I ask why docker LXC's are a no-no?

I will look at it.

Generally this causes issues between our use of Apparmor and other parts of our code base over and over again. So we heavily discourage it. However, with the release of Proxmox VE 9.1 you can use OCI templates for application containers on Proxmox VE.

This means that you can run Docker containers as application containers on Proxmox VE like you would any other LXC container. It works by translating the Docker images (which are OCI images) to LXC containers on Proxmox VE.

You can check it out here in the docs already [1].
