Some Dockerfiles for docker.
Making your own images is easy!
Let's assume you want to create an image of the ruby-2.0.0 Dockerfile. Simply check out this repo and cd into the ruby-2.0.0-stable directory and:
sudo docker build -t ruby-2.0.0 .
That will build an image tagged ruby-2.0.0:latest
I am using multiple builds at times to make final images. As such, Dockerfiles make assumptions that certain images exist.
For example, the puppet-3.2.4 Dockerfile assumes that there is an image named 'ruby-1.9.3'. This may be created from the Dockerfile under the ruby-1.9.3-p448 folder with the tag name ruby-1.9.3.
Once that image is created, the puppet Dockerfile build should run just fine!
