docker-machine-ipconfig
Allows one to toggle between static and DHCP docker-machine network interface settings.
This is helpful when running a local docker swarm and you need to have your docker machine VMs maintain static IP addresses.
Works for Mac OS x and Cygwin docker clients. Probably works on Linux, but hasn't been tested there yet.
Installation
Place the docker-machine-ipconfig script on your path in whatever manner you see fit.
Usage
Warning: Using this script to modify your machine configuration will stomp on and/or delete an existing /var/lib/boot2docker/bootsync.sh file. There are no checks at the moment to prevent adverse behavior. Use responsibly. Any pull requests to address this are welcome :)
