dockerinoz - simple Dockerfile (security) best practices verification

dockerinoz is a very small and simple tool which allows you to verify the content of Dockerfiles against a given best practice. It’s nothing more than a fancy grep using a bit more than just simple regular expressions. This approach allows for very quick verifications which is especially important when implementing dockerinoz into your build pipeline. It also makes dockerinoz super easy to modify and extend - especially as the rules are just regular expressions in a json file (rules.json).
