Docker on LXC

1 min read

Notes (to be cleaned up and made useful later):

Create three Docker LXCs with the script.

  • Enable Portainer on the first one and the agent on the others (it is an option in the script)
  • Do not expose the Docker port (its not good security and will be an issue later)
  • Save the conf from the first to use on the others for simplicity and consistency
  • Give each node at least 10GB of storage but don’t worry about container data - that is solved below with the ZFS mount
  • Docker swarm init and create a worker token on the first node, and add it to the other two (docker swarm init initializes and generates the command for the other two) In Proxmox terminal, create the ZFS sub-volume and size it:
zfs list
zfs create zfs10/subvol-docker
zfs set quota=70G zfs10/subvol-docker
zfs list

Then go to the Datacenter level in Proxmox, select Storage, Add, Directory. Fill it in like so: Then go to the LXC (each of them) and in the resources, add a mount point like this:
