使用docker compose部署emqx集群的示例

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 => []}
