Docker 容器编排

1、清理和准备

上篇文章 创建并准备一个镜像

#移除容器
docker rm -f $(docker ps -aq)

redis默认文件下载
docker_boot.zip下载
上传到 /app/redis/redis.conf

2、docker-compose.yml

version: "3"
 
services:
  microService:
    image: boot:1.0
    container_name: ms_01
    ports:
      - "6001:6001"
    volumes:
      - /app/microService:/data
    networks: 
      - atguigu_net 
    depends_on: 
      - redis
      - mysql
  redis:
    image: redis:6.0.8
    container_name: redis_01
    ports:
      - "6379:6379"
    volumes:
      - /app/redis/redis.conf:/etc/redis/redis.conf
      - /app/redis/data:/data
    networks: 
      - atguigu_net
    command: redis-server /etc/redis/redis.conf
  mysql:
    image: mysql:5.7
    container_name: mysql_01
    environment:
      MYSQL_ROOT_PASSWORD: 'root'
      MYSQL_ALLOW_EMPTY_PASSWORD: 'no'
      MYSQL_DATABASE: 'db2021'
      MYSQL_USER: 'zzyy'
      MYSQL_PASSWORD: 'zzyy123'
    ports:
       - "3306:3306"
    volumes:
       - /app/mysql/db:/var/lib/mysql
       - /app/mysql/conf/my.cnf:/etc/my.cnf
       - /app/mysql/init:/docker-entrypoint-initdb.d
    networks:
      - atguigu_net
    command: --default-authentication-plugin=mysql_native_password #解决外部无法访问
    
networks: 
   atguigu_net: 
 

3、Compose常用命令

docker-compose -h                           # 查看帮助
docker-compose up                           # 启动所有docker-compose服务
docker-compose up -d                        # 启动所有docker-compose服务并后台运行
docker-compose down                         # 停止并删除容器、网络、卷、镜像。
docker-compose exec  yml里面的服务id                 # 进入容器实例内部  docker-compose exec docker-compose.yml文件中写的服务id /bin/bash
docker-compose ps                      # 展示当前docker-compose编排过的运行的所有容器
docker-compose top                     # 展示当前docker-compose编排过的容器进程
docker-compose logs  yml里面的服务id     # 查看容器输出日志
dokcer-compose config     # 检查配置
dokcer-compose config -q  # 检查配置，有问题才有输出
docker-compose restart   # 重启服务
docker-compose start     # 启动服务
docker-compose stop      # 停止服务
