docker compose +network

docker 列出每个容器的IP
常用方法有两种

docker inspect 容器ID | grep IPAddress

方法二

查看docker name：

sudo docker inspect -f='{{.Name}}' $(sudo docker ps -a -q)

查看dockers ip：

sudo docker inspect -f='{{.NetworkSettings.IPAddress}}' $(sudo docker ps -a -q)

综上，我们可以写出以下脚本列出所有容器对应的名称，端口，及ip

 docker inspect -f='{{.Name}} {{.NetworkSettings.IPAddress}} {{.HostConfig.PortBindings}}' $(docker ps -aq)
 

docker consul 的conpose.yml

version: '3'

services:

  consul-agent-1: &consul-agent
    image: consul:latest
    networks:
      - consul-demo
    command: "agent -retry-join consul-server-bootstrap -client 0.0.0.0"

  consul-agent-2:
    <<: *consul-agent

  consul-agent-3:
    <<: *consul-agent

  consul-server-1: &consul-server
    <<: *consul-agent
    command: "agent -server -retry-join consul-server-bootstrap -client 0.0.0.0"

  consul-server-2:
    <<: *consul-server

  consul-server-bootstrap:
    <<: *consul-agent
    ports:
      - "8400:8400"
      - "8500:8500"
      - "8600:8600"
      - "8600:8600/udp"
    command: "agent -server -bootstrap-expect 3 -ui -client 0.0.0.0"

指定docker ip 和network

查看网络模式

docker network ls

创建一个新的bridge网络

docker network create --driver bridge --subnet=172.18.12.0/16 --gateway=172.18.1.1 mynet

查看网络信息

docker network inspect mynet

创建容器并指定容器ip

docker run -e TZ="Asia/Shanghai" --privileged -itd -h hadoop01.com --name hadoop01 --network=mynet --ip 172.18.12.1 centos /usr/sbin/init

运行容器

docker exec -it hadoop01 /bin/bash
