# Depending on your docker configuration, root might be required. If your nrpe user has rights

# checked.
#
# The script checks if a container is running.
#   OK - running
#   WARNING - restarting
#   CRITICAL - stopped
#   UNKNOWN - does not exist
#
# CHANGELOG - March 20, 2017
#  - Removes Ghost State Check, Checks for Restarting State, Properly finds the Networking IP addresses
#  - Returns unknown (exit code 3) if docker binary is missing, unable to talk to the daemon, or if container id is missing
