GoCage

Jail management tool for FreeBSD, written in Go.
Support iocage jails, so they can coexist.
Gocage is meant to be a complete jail management tool with network, snapshots, jail cloning support and a web interface. This is the hypothetic future.

At present time, it list and stops jails.

List jails

Nothing fancy, just use
gocage list

Specify fields to display

Use -o to specify which fields you want to display:

gocage list -o JID,Name,Running,Config.Boot,Config.Comment  
+=====+==========+=========+=============+================+  
| JID | Name     | Running | Config.Boot | Config.Comment |  
+=====+==========+=========+=============+================+  
| 183 | test     | true    | 1           | none           |  
+-----+----------+---------+-------------+----------------+  
| 29  | srv-irc  | true    | 1           |                |  
+-----+----------+---------+-------------+----------------+  
|     | srv-web  | false   | 0           |                |  
+-----+----------+---------+-------------+----------------+  
| 22  | srv-dns1 | true    | 1           |                |  
+-----+----------+---------+-------------+----------------+  

Filter jails

By name

Just add name on gocage list command :

gocage list srv-bdd srv-web
+=====+=========+=================+=======================+=========+
| JID | Name    | Config.Release  | Config.Ip4_addr       | Running |
+=====+=========+=================+=======================+=========+
| 98  | srv-db  | 13.0-RELEASE-p5 | vnet0|192.168.1.56/24 | true    |
+-----+---------+-----------------+-----------------------+---------+
| 41  | srv-web | 13.0-RELEASE-p4 | vnet0|192.168.1.26/24 | true    |
+-----+---------+-----------------+-----------------------+---------+

By field value

You can filter jails with -f option, followed by key=value. Suppose you want to see only active at boot jails:

gocage list -f Config.Boot=1 -o JID,Name,Running,Config.Boot,Config.Comment
+=====+==========+=========+=============+================+
| JID | Name     | Running | Config.Boot | Config.Comment |
+=====+==========+=========+=============+================+
| 183 | test     | true    | 1           | none           |
+-----+----------+---------+-------------+----------------+
| 29  | srv-irc  | true    | 1           |                |
+-----+----------+---------+-------------+----------------+
|     | srv-db   | false   | 1           | none           |
+-----+----------+---------+-------------+----------------+
| 22  | srv-dns1 | true    | 1           |                |
+-----+----------+---------+-------------+----------------+

Now, only active at boot and running :

gocage list -f Config.Boot=1,Running=true -o JID,Name,Running,Config.Boot
+=====+==========+=========+=============+
| JID | Name     | Running | Config.Boot |
+=====+==========+=========+=============+
| 183 | test     | true    | 1           |
+-----+----------+---------+-------------+
| 29  | srv-irc  | true    | 1           |
+-----+----------+---------+-------------+
| 22  | srv-dns1 | true    | 1           |
+-----+----------+---------+-------------+

Stop jails
