Docker Builder

This a Builder implementation that builds Docker images inside Docker. So meta.

It does the following:

1. Clones the GitHub repo.
2. Pulls that last built docker image for the given branch.
3. Builds a new image.
4. Tags the new image with latest as well as the name of the branch and the git sha.
5. Pushes the image to the docker registry.

Usage

This image expects that the following files to be present:

• /var/run/conveyor/.dockercfg: .dockercfg file for credentials to use when pulling.
• /var/run/conveyor/.ssh: Should container an id_rsa and id_rsa.pub file which gives access to pull GitHub repos.
