Run Rocket under Docker.

This gives you access to the rkt executable without having to install rkt on your system. You do, however, have to have docker installed.

Install the gem:

gem install rocker-docket

Once installed, you can:

• Build the image : rocker-docket build
• Update to the latest version of rocket: rocker-docket update.

Updating will also build. If you have never run build before, it will get the latest version of rocket.

Use it just like you would use the rkt CLI, after you have built the image.

rkt help

By default, the host directory /var/lib/rkt will be mounted in the container, for rkt operations. You can override this by setting ROCKET_DIR.
