From OMV6 to Proxmox

[jekel35]

Hey all, I'm thinking of making the change from OMV6 to proxmox. So here's my question that I need help on Should I spin up a vm to run docker/portainer and have all my containers on there or should I just use the promox built-in containers. My only concern about making sure that the containers can communicate with one another. Essentially using Trash's guide to make sure that containers can move items. Also, I'm using separate server to host all my files so it'll have to be able to reach out and use those folders as well. Thoughts?

LXCs and docker containers are something quite different. With LXCs you got a container that contains a whole operating system, just without the kernel. You have to administrate that LXC like you would manage a VM. With Docker containers you just containerize applications. LXCs also aren't using this "throw away" style of containerization.

So this really depends on your use case. If you just want some ready to use appliances I would set up a portainer VM. If you prefer to set up and administrate everything yourself, so that you don't have to trust or rely on other people, then I would use LXCs.

Regarding your separate fileserver: With LXCs you got two options. Unsecure privileged and more secure unprivileged LXCs. Only the less secure privileged ones will allow you to directly mount NFS/SMB shares. For unprivileged LXCs, as a workaround, you have to mount the SMB/NFS shares on the host and then bind-mount them from the host into the LXC.
