sewatech/mosquitto repository overview

⁠Content

• Debian Jessie
• Mosquitto server
• Mosquitto clients (pub & sub)

⁠Build the image

docker build -t sewatech/mosquitto .

⁠Run the broker

docker run --name mosquitto -p 1883:1883 -d sewatech/mosquitto

The --name argument is optional. It is useful for docker exec command, or if you want to stop and start the container.

⁠Publish messages

If you want to publish a message from the mosquitto container (works with docker 1.3+) :

docker exec mosquitto mosquitto_pub  -t some/Topic -m "My message"

If you want to publish a message from a different container :

docker run --rm -ti sewatech/mosquitto mosquitto_pub -h 172.17.42.1 -t some/Topic -m "My message"

Here, 172.17.42.1 is the IP address of the broker. If the broker is the docker host, you may find the address automatically :

docker run --rm -ti sewatech/mosquitto mosquitto_pub -h `ifconfig docker0 | grep 'inet adr:' | cut -d: -f2 | awk '{ print $1}'` -t some/Topic -m "My message"

See http://mosquitto.org/man/mosquitto_pub-1.html⁠ for other arguments

⁠Read messages

If you want to subscribe to topics from the mosquitto container (works with docker 1.3+) :

docker exec mosquitto mosquitto_sub -t some/Topic

If you want to subscribe to topics from a different container :

docker run --rm -ti sewatech/mosquitto mosquitto_sub -h 172.17.42.1 -t some/Topic

Same as above for the IP address.
