Managing Jails

As of TrueNAS CORE 13.3, this feature is untested and provided without support to the TrueNAS Community.

Users with a critical need to use containers or virtualization solutions in production should migrate to the tested and supported virtualization features available in TrueNAS SCALE. TrueNAS Enterprise customers can contact iXsystems to schedule a TrueNAS SCALE deployment. See CORE to SCALE Migrations for more information.

The Jails screen displays a list of jails installed on your system.


Jail status messages and command output are stored in /var/log/iocage.log.

Applying Operations to Multiple Jails

Operations can be applied to multiple jails by selecting those jails with the checkboxes on the left. After selecting one or more jails, icons display which can be used on the selected jails:

starts jails

stops jails

updates jails

deletes jails

To see more information such as IPV4, IPV6, jail TYPE, and whether it is a TEMPLATE or BASEJAIL click > to expand a jail. Additional options for that jail also display.

For more information on jail options, see Jails.

Modifying Jail IP Addresses

To modify the IP address information for a jail, click the for the jail and then EDIT instead of issuing the networking commands directly from the command line of the jail. This ensures changes are saved and survive a jail or TrueNAS reboot.
