Install openITCOCKPIT in LXC

Tags: Tutorial | openITCOCKPIT | LXC | Virtualization

In the course of migrating some services from very old openVZ machines I decided to use a powerful KVM Host with Proxmox to manage some applications in LXC and docker.

With my openITCOCKPIT installation, the migration to an LXC did not work using LXC default settings!

openITCOCKPIT needs to create own docker containers, but using docker in LXC wasn´t as easy as I thought.

After some annoying hours I got it working and in the end it wasn't that hard to set up :)

Now it´s my productive setup.

In the following my experiences on the topic and a factual explanation as possible :)
