Docker is a convoluted mess of overlays and truly weird network settings. I found that I have no interest in application containers and would much prefer to set up multiple services in a system container (or VM) as if it was a bare-metal server. I deploy a small Proxmox cluster with Proxmox Backup Server in a CT on each node and often use scripts from https://community-scripts.github.io/ProxmoxVE/. Everything is automatically backed up (and remote sync'd twice) with a deduplication factor of 10. A Dockerless Homelab FTW!
