docker-compose应用

需求编写compose模板文件，实现同时启动tomcat、mysql、redis容器。

1、编写模板文件

#新建文件夹
mkdir -p /tzh/compose_test
?
#进入文件夹
cd /tzh/compose_test
?
#新建docker-compose.yml文件，内容如下：
vim docker-compose.yml

docker-compose.yml文件内容如下

version: ‘3‘
services:
  redis:
    image: redis
    ports:
      - "16379:6379"
    container_name: "redis"
    networks:
      - dev
  mysql:
    image: centos/mysql-57-centos7
    environment: 
            MYSQL_ROOT_PASSWORD: "root"
    ports: 
      - "3308:3306"
    container_name: mysql
    networks:
      - dev
  tomcat:
    image: tomcat
    ports:
      - "8080:8080"
    networks:
      - dev
      - pro
networks:
  dev:
    driver: bridge
  pro:
    driver: bridge

2、启动

#进到当前目录
[root@tzh compose_test]# pwd
/tzh/compose_test
[root@tzh compose_test]# ls
docker-compose.yml
#启动  docker-compose up -d

3、验证

[root@tzh compose_test]# docker ps
CONTAINER ID        IMAGE                     COMMAND                  CREATED             STATUS              PORTS                     NAMES

d9d621c870e2        centos/mysql-57-centos7   "container-entrypoin…"   11 minutes ago      Up About a minute   0.0.0.0:3308->3306/tcp    mysql
eda7e1c5c027        redis                     "docker-entrypoint.s…"   11 minutes ago      Up About a minute   0.0.0.0:16379->6379/tcp   redis

可以看到我们刚刚跑的容器了
