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
11fb9825321f tomcat "catalina.sh run" 26 seconds ago Up 26 seconds 0.0.0.0:8080->8080/tcp compose_test_web_1
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
