This is the base Docker image that I use for my blog.
The repo for that is more interesting and you can find it at:

Originally the CDC repo had a single Dockerfile which contained all the stuff in the Dockerfile here. What I found though was that installing git, curl, npm, etc on every build when I posted a new blog post really made for some long builds.
Those packages almost never change, so I pulled that stuff out into the Dockerfile you find here in this repo. This gets built nightly by Travis, and pushed to Dockerhub. I then use that built image as the base image for CDC builds, which speeds up my build times for that repo.
