Updating jailsΒΆ

Updates are handled with the freebsd-update(8) utility. Jails can be updated while they are stopped or running.

To update a jail to latest patch level run:

iocage update UUID

This will create a back-out snapshot of the jail automatically.

When finished with updating and the jail is working OK, simply remove the snapshot:

iocage snapremove UUID@snapshotname

In case the update breaks the jail, simply revert back to the snapshot:

iocage rollback UUID@snapshotname

If you’d like to test updating without affecting a jail, create a clone and update the clone the same way as outlined above.

To clone run:

iocage clone UUID tag=testupdate
