1、docker-compose.yml 文件，内容如下：

version: '3'
services:
  emqx1:
    image: emqx:5.0.26
    container_name: emqx1
    environment:
    - "EMQX_NODE_NAME=emqx@node1.emqx.io"
    - "EMQX_CLUSTER__DISCOVERY_STRATEGY=static"
    - "EMQX_CLUSTER__STATIC__SEEDS=[emqx@node1.emqx.io,emqx@node2.emqx.io]"
    healthcheck:
      test: ["CMD", "/opt/emqx/bin/emqx_ctl", "status"]
      interval: 5s
      timeout: 25s
      retries: 5
    networks:
      emqx-bridge:
        aliases:
        - node1.emqx.io
    ports:
      - 1883:1883
      - 8083:8083
      - 8084:8084
      - 8883:8883
      - 18083:18083 
    # volumes:
    #   - $PWD/emqx1_data:/opt/emqx/data
  emqx2:
    image: emqx:5.0.26
    container_name: emqx2
    environment:
    - "EMQX_NODE_NAME=emqx@node2.emqx.io"
    - "EMQX_CLUSTER__DISCOVERY_STRATEGY=static"
    - "EMQX_CLUSTER__STATIC__SEEDS=[emqx@node1.emqx.io,emqx@node2.emqx.io]"
    healthcheck:
      test: ["CMD", "/opt/emqx/bin/emqx_ctl", "status"]
      interval: 5s
      timeout: 25s
      retries: 5
    networks:
      emqx-bridge:
        aliases:
        - node2.emqx.io
    # volumes:
    #   - $PWD/emqx2_data:/opt/emqx/data
networks:
  emqx-bridge:
    driver: bridge

2、通过命令行切换 docker-compose.yml 文件所在目录，然后输入以下命令启动 EMQX 集群：

docker-compose up -d

3、查看集群状态

$ docker exec -it emqx1 sh -c "emqx_ctl cluster status"
Cluster status: #{running_nodes => ['emqx@node1.emqx.com','emqx@node2.emqx.com'],
                  stopped_nodes => []}
