Not having the backslashes for the `docker run` command resulted in an
error.
Using `80:80` is ignored. While it will work on port 80, it fails when
using any other port such as `3000:80`. Using `3000:8080` works.
Volumes should have a colon on the end, otherwise you get a `ERROR:
yaml.scanner.ScannerError: mapping values are not allowed here`
That said, the new Docker install isn't working for me yet, but I love
the idea of bundling the nginx files with the recipes container.
