Note on running Apache OpenWhisk actions locally for development

When you develop an action for Apache OpenWhisk it can become cumbersome and time-consuming to upload the action to your OpenWhisk instance in order to test it. This is especially the case when your (Node-based) action contains NPM dependencies.
You can always use Node.js to run the action locally. However, ideally one wants to run in an environment as similar to the cloud as possible - in this case run within an OpenWhisk Docker image.
This is where comes in handy: it does exactly this - run the action locally in an OpenWhisk container. I hope this tool will make it into wsk or a similar tool for local OpenWhisk action development.
