Routes CloudEvents that are received on an input UNIX Socket port to an output UNIX Socket port and an MQTT output port.

This example require an armv7 based microprocessor.

1. Build the docker image which will be used to compile the binary: docker build . -t armv7
2. Build the binary docker run -v ${PWD}/../../:/cerk -ti armv7
3. Copy target/armv7-unknown-linux-gnueabihf/release/unix_socket_and_mqtt_on_armv7 to the armv7 based microprocessor.
4. Start an MQTT broker
5. Start the router with the env variable MQTT_BROKER_URL which points to the broker, e.g. MQTT_BROKER_URL=tpc://192.1.1.55:1883 ./unix_socket_and_mqtt_on_armv7
