Managing Jails

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.

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:

play_arrow starts jails

stop stops jails

update updates jails

delete 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 Creating Jails

To modify the IP address information for a jail, click the chevron_right 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.

To updata a jail to the most current patch level of the installed FreeBSD release, click > to expand the jail and then click Update. This does not change the release. For example, a jail installed with FreeBSD 11.2-RELEASE can update to p15 or the latest patch of 11.2, but not an 11.3-RELEASE-p# version of FreeBSD.

Using Upgrade replaces the jail FreeBSD operating system with a new release of FreeBSD, such as taking a jail from FreeBSD 11.2-RELEASE to 11.3-RELEASE. To upgrade a jail, stop it, open the TrueNAS Shell and enter command iocage upgrade name -r release, where name is the plugin jail name and release is the desired FreeBSD release.

It is possible to manually remove unused releases from the /iocage/releases/ dataset after upgrading a jail.

The release must not be in use by any jail on the system!
