#	Mnemonic:	Dockerfile
#	Abstract:	Build file which creaes a runtime image for the listener.
#				Building should be as simple as:
#
#					docker build -f sidecars/listener/Dockerfile -t mc_listener:xx.xx .
#
#				Running the image in a container:
#					The fifo output directory needs to be mounted to the container
#					e.g.  -v /exports/mcl/fifos:/tmp/mcl/fifos.  The internal
#					directory can be supplied on the command line using -d path, but
#					should not be needed.
#
#					The RMR listen port must be properly exposed to the container. The
#					internal default is 4560, and can be changed with the -p port option
#					on the command line (needed if running from docker-compose). Typical
#					exposure might be  -p <host-port>:4560  on the docker run command.
#
#					The MC listener application does NOT need route table updates and thus
#					there is NO need to expose the route table generator port on this
#					container.
