The goal of Jailer is to solve the same problems that Docker solved on Linux, but for FreeBSD. Imagine a project where next to your already existing Dockerfile you have a Jailerfile, which can be used to start a FreeBSD jail running your installed & configurated application.
This software is in it's infancy. Use at your own risk. Have fun.

A jail can be described in a Jailerfile. The goal is to keep the syntax as similar to a Dockerfile as possible.
Example:
FROM freebsd
RUN echo "Hello Jailer!"
Not all commands are implemented yet. Most commands need to run as root:
Usage:
jailer [flags]
jailer [command]
Available Commands:
build Build an image from a Jailerfile
config Print current config
dev Subcommand for development only
exec Execute a command inside an existing jail
fetch Fetch base from FreeBSD mirror
help Help about any command
info Display system-wide information
init Init for jailer. Creates zfs datasets
ps List active jails
restart Restart one or more jails
rm Remove one or more jails
run Run a command in a new jail
start Start one or more stopped jails
