MQTT stuff

We use mosquitto as a MQTT server.

Install mosquitto

(Skip if you don't need mosquitto CLI tools and want to run it just in Docker.)

brew install mosquitto

Run MQTT broker in docker container

 docker run -ti -p 1883:1883 -p 91:9001 toke/mosquitto

Publish message example

mosquitto_pub  -h ip_or_hostname -p 1883 -m "test message" -t roomId/topicId
