How to autoprovision additional disks using profiles or Ansible in a cluster?

LXD
2

So what this is looking like to me for the above scenario of additional disks in instances (containers & virtual-machines), is that these additional disks are best to be on storage managed externally to LXD and then their backends referenced in source.

Configuration of this seems to be:

  • figure out whether to use at least 1 LXD managed storage pool for the instances, or go fully external managed storage… probably on ZFS
  • figure out how to reference source dymanically
  • prepare additional storage using external storage management tools
  • potentially have to configure cgroup & apparmor permissions
  • stipulate --target for all instances
  • get all of the above to work in Ansible

size is only supported for the root disk
pool is not required
source is required and can refer to one of several storage backends

Anything else or other pointers that you can think of?
