useful docker commands

.bashrc

# Purpose: reset docker environment
# Argument (optional): all
#
# "docker-reset" will kill and remove all containers (except dinghy-http-proxy),
# dangling images, and volumes. It won't remove networks.
#
# "docker-reset all" will do everything in 'docker-reset' and remove all
# networks, too.
#
# Prerequisite: you'll need to install docker-clean: brew install docker-clean
#
# To use dinghy-http-proxy with docker for mac, follow these instructions:
#   https://github.com/codekitchen/dinghy-http-proxy#using-outside-of-dinghy

# latency. Run this function in a separate shell window when that happens.
