Docker image based on Dwolla’s Jenkins Agent Chef Docker image making nvm and chef available to Jenkins jobs. With that, you get the ancillary benefits of a Ruby environment.
Example command to build this and add an image tag.
docker build -t my-really-cool-docker-image .
Example command to run this while mounting the current working directory:
docker run -it
-v "$PWD":/home/jenkins/$(basename $PWD) \
my-really-cool-docker-image /bin/bash
