![]() ![]() This process would be very similar to LVM, as you can mount subvolumes wherever you please.Īnd finally, have you considered NFS? Specifying an NFS connection in a container image is a good way to get shared storage. This is the best of both worlds, as it's a filesystem or file level snapshot mechanism that doesn't require you to manage both files an a volume manager separately. Third, you could snapshot BTRFS subvolumes. ![]() Using LVM would be safer than reflinked copies, as changes to the original are handled gracefully by updating all snapshots with origin updates. Thin LVM would be best for this approach, and you would accomplish this by mounting the snapshot itself rather than using a snapshot as a way to roll back an origin volume like we traditionally do. Or you could use something like LVM snapshots to quickly create / clone filesystems that are differentials of an original. If you do this, you'll probably want to make the original immutable so the reflinked copy doesn't get borked. The Docker menu () displays the Docker Subscription Service Agreement window. In the example below, the Applications folder is in grid view mode. Double-click Docker.app in the Applications folder to start Docker. You could copy using reflinks `cp -reflink=always', which will create a differential file that references a static original. Double-click Docker.dmg to open the installer, then drag the Docker icon to the Applications folder. ![]()
