docker-compose 安装consul集群

• 创建consul集群专属网络, （默认使用bridge模式）

docker network create my_consul_net

• 编写docker-compose.yaml文件
  备注：文件中是创建三个server（consul_node1，consul_node2，consul_node3）和一个client（consul_node4）,并在consul_node4上面提供 web UI 服务，web访问端口是8500

version: '3'
networks:
  my_consul_net:

services:
  consul1:
    image: consul
    container_name: consul_node1
    command: agent -server -bootstrap-expect=3 -node=consul_node1 -bind=0.0.0.0 -client=0.0.0.0 -datacenter=dc1
    networks:
      - my_consul_net

  consul2:
    image: consul
    container_name: consul_node2
    command: agent -server -retry-join=consul_node1 -node=consul_node2 -bind=0.0.0.0 -client=0.0.0.0 -datacenter=dc1
    depends_on:
      - consul1
    networks:
      - my_consul_net

  consul3:
    image: consul
    container_name: consul_node3
    command: agent -server -retry-join=consul_node1 -node=consul_node3 -bind=0.0.0.0 -client=0.0.0.0 -datacenter=dc1
    depends_on:
      - consul1
    networks:
      - my_consul_net

  consul4:
    image: consul
    container_name: consul_node4
    command: agent -retry-join=consul_node1 -node=consul_node4 -bind=0.0.0.0 -client=0.0.0.0 -datacenter=dc1 -ui
    ports:
    - 8500:8500
    depends_on:
      - consul2
      - consul3
    networks:
      - my_consul_net

• 使用命令启动

docker-compose up -d

• 查看consul集群容器

docker ps

docker ps
