How to discover Docker Public ports with AWS ECS

	# When wanting to search for port 7000 (example) you would query the ECS agent endpoint searching for your docker
	# container by its ID ($HOSTNAME). You can then parse the resulting json yourself, or use JQ to find the HostPort

	# curl -sS http://172.17.0.1:51678/v1/tasks?dockerid=$HOSTNAME \
	# \| jq '.Containers[].Ports[] \| select (.ContainerPort == 7000) \| .HostPort'

	# The following will create env vars identifying the public port numbers for mapped private ports
	# (example assuming docker is exposing 80,443 and 8080)
	#
	# PUBLIC_PORT_80=32777
