Running EMQX in Docker (Contain a simple docker-compose cluster)

Tips for data persistent and docker-compose

1. If you want to persist data generated in the EMQX Docker container, you need to keep the following directories, so that the data will persist even if the container no longer exists.

   /opt/emqx/data
   /opt/emqx/etc
   /opt/emqx/log

2. In Docker, localhost or 127.0.0.1 points to the internal address of the container. Use the host’s IP or host networking to access the host address. If you are using Docker for Mac or Docker for Windows, you can use host.docker.internal as the host address.

3. As EMQX uses data/mnesia/<node_name> as the data storage directory, it is important to select a fixed identifier, such as the hostname or FQDN, as the node name. This practice avoids data loss caused by node name changes.

Run a Single Container

1. Get docker image from Docker Hub.

   $ docker pull emqx/emqx:v4.0.0

2. Start docker container.

   $ docker run -d --name emqx -p 1883:1883 -p 8081:8081 -p 8083:8083 -p 8883:8883 -p 8084:8084 -p 18083:18083 emqx/emqx:v4.0.0

Create a Simple Static Cluster by Docker-Compose

Please note that the Docker Compose example file in this section is only applicable to local testing. If you need to deploy a cluster in a production environment, please refer to Create a cluster.

1. Create docker-compose.yaml file.

   version: '3'
   
   services:
     emqx1:
       image: emqx/emqx:v4.0.0
       environment:
       - "EMQX_NAME=emqx"
       - "EMQX_HOST=node1.emqx.io"
       - "EMQX_CLUSTER__DISCOVERY=static"
       - "EMQX_CLUSTER__STATIC__SEEDS=emqx@node1.emqx.io, emqx@node2.emqx.io"
       - "EMQX_ZONE__EXTERNAL__RETRY_INTERVAL=2s"
       - "EMQX_MQTT__MAX_TOPIC_ALIAS=10"
       volumes:
           - ./tmp/emqx.lic:/opt/emqx/etc/emqx.lic
       healthcheck:
         test: ["CMD", "/opt/emqx/bin/emqx_ctl", "status"]
         interval: 5s
         timeout: 25s
         retries: 5
       networks:
         emqx-bridge:
           aliases:
           - node1.emqx.io
   
     emqx2:
       image: emqx/emqx:v4.0.0
       environment:
       - "EMQX_NAME=emqx"
       - "EMQX_HOST=node2.emqx.io"
       - "EMQX_CLUSTER__DISCOVERY=static"
       - "EMQX_CLUSTER__STATIC__SEEDS=emqx@node1.emqx.io, emqx@node2.emqx.io"
       - "EMQX_ZONE__EXTERNAL__RETRY_INTERVAL=2s"
       - "EMQX_MQTT__MAX_TOPIC_ALIAS=10"
       volumes:
           - ./tmp/emqx.lic:/opt/emqx/etc/emqx.lic
       healthcheck:
         test: ["CMD", "/opt/emqx/bin/emqx_ctl", "status"]
         interval: 5s
         timeout: 25s
         retries: 5
       networks:
         emqx-bridge:
           aliases:
           - node2.emqx.io
   
     client:
       image: python:3.7.2-alpine3.9
       depends_on:
         - emqx1
         - emqx2
       tty: true
       networks:
           emqx-bridge:
   
   networks:
     emqx-bridge:
       driver: bridge

2. Start docker-compose cluster.

   $ docker-compose -p my_emqx up -d

3. View cluster.

   $ docker exec -it my_emqx_emqx1_1 sh -c "emqx_ctl cluster status"
   Cluster status: #{running_nodes => ['emqx@node1.emqx.io','emqx@node2.emqx.io'],
                     stopped_nodes => []}
