Bash Script for Nagios to Check Status of Docker Container
#!/bin/bash
# Author: Erik Kristensen
# Email: erik@erikkristensen.com
# License: MIT
# Nagios Usage: check_nrpe!check_docker_container!_container_id_
# Usage: ./check_docker_container.sh _container_id_
#
# Depending on your docker configuration, root might be required. If your nrpe user has rights
# to talk to the docker daemon, then root is not required. This is why root privileges are not
