Here is my collection of folders containing Dockerfile from around the web.

1. Build and/or navigate to a container folder.

2. Clone this and navigate into the node-ubuntu folder.

3. Build a Docker image using the Dockerfile:

   docker build -t msanand/node .

4. Create a Node container from the custom image and link it to the Redis container:

   docker run -d --name node -p 8080 --link redis:redis msanand/node
