How to apply snapshots.expiry: 3d to all my container using profile?

1

Hi,
I was testing snapshot expiry and it work very well on a per container setting.

I try to modify the default profile to add in the config setting the snapshots.expiry without success.

Lxc info container would not give the expiration time !

Is this normal ?

2

The expiry only applies to new snapshots, not to the existing ones, could that be the problem?

Setting the key on the profile should show up in lxc config show --expanded NAME , if thatā€™s the case, then I would expect new snapshots to have the proper expiry.

3

I confirm that the snapshot was new and taken after modification apply to the profile !

The first snap was done with the profile config
The second snap was done with the container config

I have recreate the container and tested it twice

Snapshots:

snap1 (taken at 2020/03/13 17:03 UTC) (expires at 2020/03/13 17:04 UTC) (stateless)
