docker swarm多节点部署zookeeper 3.4.14

前提条件是二个主机处于docker swarm mode下（如何建立swarm集群请百度）

Docker node ls 查看是否处于该模式

1)自定义overlay网络[1.13+]

#docker network create    --attachable  -d overlay  --subnet 172.16.15.0/24  --gateway 172.16.15.254  zk-overlay

--attachable 创建swarm mode的overlay网络,允许手工创建容器连接到该网络.

在二个及二个以上节点查看网络情况

#docker network ls

2）节点1

version: '3.1'

services:
  zoo1:
    image: zookeeper
    restart: always
    hostname: zoo1
    container_name: zoo1
    ports:
      - 2181:2181
      - 2888:2888
      - 2388:3888
    environment:
      TZ: 'Asia/Shanghai'
      ZOO_MY_ID: 1
      ZOO_SERVERS: server.1=0.0.0.0:2888:3888 server.2=zoo2:2888:3888
    networks:
      - zk-overlay
networks:
   zk-overlay:
      external: true

3) 节点2

version: '3.1'

services:
  zoo2:
    image: zookeeper
    restart: always
    hostname: zoo2
    container_name: zoo2
    ports:
      - 2181:2181
      - 2888:2888
      - 2388:3888
    environment:
      TZ: 'Asia/Shanghai'
      ZOO_MY_ID: 2
      ZOO_SERVERS: server.1=zoo1:2888:3888 server.2=0.0.0.0:2888:3888
    networks:
      - zk-overlay
networks:
    zk-overlay:
      external: true

4) 其他节点类似

5）查看zk运行情况

 docker logs -f zoo1

 docker logs -f zoo2
