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.

List jails

Nothing fancy, 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 | +-----+----------+---------+-------------+
