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 => []}
