Install MQTT for Linux - using docker

Docker is very popular nowaday, so instead of installing MQTT broker directly on Linux, I try to find if there are any MQTT docker image. It's great that there is an official Mosquitto implementation of MQTT broker by Eclipse. Here are the procedure to install and test these Mosquitto-MQTT broker for Linux.

Linux server

    I'm running and Ubuntu 16.04.2 - 64 bit virtual machine on Digital Ocean, but I think the setup procedure should be the same on a real Linux machine.  I originally run a 32bit version ubuntu VM, but docker only support 64bit version, so I destroy the previous one and create a new 64bit version.

Install Docker

  The first step is , of course, to install the Docker. I use "curl" to install, so install curl first,

sudo apt-get update sudo apt-get install curl

Then install docker

curl -fsSL https://get.docker.com/ | sh

You also need to add your user to docker group

sudo usermod -aG docker YOUR_USER_NAME

The following command will download the eclipse-mosquitto image then create a container (that also mean running the mosquitto services)
web sites for the eclipse-mosquitto https://hub.docker.com/_/eclipse-mosquitto/
docker run -it -p 1883:1883 -p 9001:9001 eclipse-mosquitto

see the result
