Deploy:

git clone https://github.com/imjorge/jenkins-on-flynn.git
cd jenkins-on-flynn
flynn create jenkins
git push flynn master

Grab the login token from the logs:

flynn log 

It looks something like e7af1c1f1574b548febd50e1bafb90b.

Go to http://jenkins.$CLUSTER_DOMAIN and enter the login token. Then configure Jenkins.

Bare in mind that, until Flynn gets persistent volumes, this is ephemeral.
