Solved How to show IP addresses of all jails

[balanga]

When I run iocage list I'm only told the state, up or down.

Is there any way to display the IP address.

ChatGPT shows this

+-----+--------+-------+--------------+--------------+
| JID | NAME   | STATE | IPV4         | IPV6         |
+-----+--------+-------+--------------+--------------+
| 1   | web1   | up    | 192.168.1.10 | -            |
| 2   | db1    | up    | 192.168.1.11 | -            |
+-----+--------+-------+--------------+--------------+

The below may not work if your jail's are running behind a version but you can give this a try.

jcreate/src/jlist.sh at main · JohnKaul/jcreate

Script to create a FreeBSD jail.conf style jail with setup script, mounts, copy-in abilities - JohnKaul/jcreate

EDIT: I'm sorry. I missed the part about using iocage. I'm sorry, the above will not work with iocage.

It seems that IOCAGE works very differently to other jails.

I can achieve what I want by writing a script using jls and the parsing the output to run jexec JID ifconfig and parsing that, but I thought there may be something ready made.

Maybe there is some configuration paramater for the fields output by iocage list.

Have you tried the -l | --long option?

iocage(8)

list     List  the  specified dataset type.  By    default, all jails are
         listed.

         Options:
         
         ...
         [-l | --long] Shows JID, NAME,    BOOT, STATE, TYPE, RE-
                       LEASE, IP4, IP6,    and TEMPLATE  informa-
                       tion.

Many thanks to T-Daemon for pointing out something I hadn't noticed and that I could use iocage list -l which gives me what I need.

ps. I noticed iocage list -PRO which looks quite interesting.
