node-red with dashboard and mosquitto in alpine docker

Cmd wrapper around docker commands to build and run an IoT dashboard kind of thing. Tries to do the right thing:

• Create the image if it does not exist then run the container.
• Run the container if it does not exist and the image does.
• Start the container if it exists and is stopped.

Usage: node-red-local [clean]
    clean: Remove container and image to start from scratch. Note that all flows and dashboard items will be lost.

dockerfile
