Thanks to the Discourse Team, we’ve finally fixed my long-running Docker issue! This means I can (finally) rip out LXC/LXD and pull Docker up to running natively on the OS instead of hiding inside a container (containers inside of containers makes me a sad sysadmin).
Just an FYI to everyone—the switchover will involve some downtime, but hopefully not a lot. Will try to get this put to bed either this evening after work or tomorrow AM. I don’t think the result will be all that visible to you guys, but it’ll save me some RAM from not having to run the separate LXC container and it’ll simplify my life quite a bit from an admin perspective.
