The recommended way to install LXD is using the snap.
By default, snapd will automatically refresh snaps when an new version is available.
What happens during a refresh of the lxd snap? Does it restart the daemon, the containers? If not, shoud we do it?
Is it safe to keep the auto-refresh on?
I have a related question, my host with a few LXD is running in a local area network, no internet connection, the snap refresh generates a lot of messages about not able to refresh in the log, is there a way to disable this? Thanks
A snap refresh will respawn the daemon but will not stop any container.
It’s in general safe to have it happen and I have dozens of production servers doing just that.
One thing you can do for peace of mind is setup a maintenance window for the snap in snapd.
This lets you pick a particular timerange throughout the week where the snap can update, picking a time where you’re likely to be awake and around should something happen.
OK, I’ve gone trough multiple updates without any issue, but I wanted to be sure. Thanks!
