nmt---Docker-compose自动化部署
1. 安装docker
source docker.sh
2. 安装pip
yum -y install python2-pip
3. 升级pip
pip install --upgrade pip==20.3 -i https://mirrors.aliyun.com/pypi/simple
4. 安装docker-compose
pip install docker-compose -i https://mirrors.aliyun.com/pypi/simple
5. 创建pes⽬录以及⼦⽬录
cd mkdir -p pes/{msyql,java,web}
6. 在pes⽬录下创建并且编辑dockerr-compose.yml⽂件
cd pes
vim docker-compose.yml
version: "3"
servies:
web: c
ontainer_name: web0
image: nginx:latest
ports:
- "80:80"
expose:
- 80
volumes:
- ./web/src/dist/:/usr/share/nginx/html/
restart: "always"
java:
mysql:
7. 添加web服务
web:
container_name: web0
image: nginx:latest
ports:
- "80:80"
expose:
- 80
volumes:
- ./web/src/dist/:/usr/share/nginx/html/
restart: "always"
8. docker-compose启动集群
cd pes
docker-compose up -d
9. docker-compose暂停集群
cd pes
docker-compose stop
10. docker-compose移除容器
docker-compose down
11. docker-compose多开容器
docker-compose up -d --scale web=5
使⽤docker-compose
docker-compose.yml
vim ./pes/docker-compose
version: "3"

volumes: - ./mysql/data/:/var/lib/mysql/
haproxy:
container_name: haproxy0
image: haproxy:latest
ports:
- "8888:8888"
- "5000:5000"
- "8080:8080"
volumes: - ./haproxy/haproxy/haproxy.cfg:/usr/local/etc/haprox y/haproxy.cfg
