# First, create a folder: /var/run/monit
# Then, make sure your user or group owns it: chown user:user /var/run/monit

# USAGE:
# use option one to start or stop
# use option two as the docker name
# use option three as the docker run command it follows '-d' f you are starting a container
#
# Example:
# $ ./monit_docker_wrapper.sh start my-name "-p 80:80 ubuntu true"
#
# I would then expect to find /var/run/monit/my-name-docker-container.pid
