jz is a command-line tool for deploying containers on FreeBSD using Jails, ZFS and pf.

jz has zero dependencies and leverages native FreeBSD functionality.

Create three containers:

 $ jz jail setup $ jz jail create nginx $ jz jail create node $ jz jail create postgres 

Under the hood, jz does the complex work of configuring the network and filesystem.

Once you've created some containers it's easy to start, attach and stop them like this:

service jail start node jexec node service jail stop node
