三、容器编排实战
案例1
第一步：创建yml文件
[[email protected] ~]# vim docker-compose.yml
version: ‘3‘
services:
web:
image: nginx:latest
ports:
- "5000:5000"
links:
- redis
redis:
image: redis第二步：启动容器
[[email protected] ~]# docker-compose up -d第三步：查看通过compose启动进程的状态
[[email protected] ~]# docker-compose ps
Name Command State Ports
----------------------------------------------------------------------------------------------------------------------------
root_redis_1 docker-entrypoint.sh redis ... Up 6379/tcp
root_web_1 nginx -g daemon off; Up 0.0.0.0:5000->5000/tcp, 80/tcp第四步：查看日志信息
[[email protected] ~]# docker-compose logs第五步：关闭服务
[[email protected] ~]# docker-compose down
Stopping root_web_1 ... done
Stopping root_redis_1 ... done
Removing root_web_1 ... done
Removing root_redis_1 ... done
Removing network root_default案例2
第一步：创建Dockerfile文件
[[email protected] ~]# vim Dockerfile
#Nginx
#Version 1.0.1
#Author zxhk
#Base image
FROM centos:7
#Maintainer
MAINTAINER [email protected]
#Commands
RUN rpm -ivh http://mirrors.aliyun.com/epel/epel-release-latest-7.noarch.rpm
RUN yum install -y nginx
RUN echo "daemon off;" >> /etc/nginx/nginx.conf
EXPOSE 80
CMD ["nginx"]第二步：执行Dockerfile文件
[[email protected] ~]# docker build -t newweb/nginx:v1-1 ./第三步：构建docker-compose.yml
[[email protected] ~]# vim docker-compose.yml
version: ‘2‘
services:
web1:
? image: newweb/nginx:v1.0.1
? volumes:
? ? ?- /data/www1:/usr/share/nginx/html
? ports:
? ? ?- "8080:80"
web2:
? image: newweb/nginx:v1.0.1
? volumes:
? ? ?- /data/www2:/usr/share/nginx/html
? ports:
? ? ?- "8081:80"
web3:
? image: newweb/nginx:v1.0.1
? volumes:
? ? ?- /data/www3:/usr/share/nginx/html
? ports:
? ? ?- "8082:80"第四步：开始构建
[[email protected] ~]# docker-compose up -d第五步：查看通过compose启动进程的状态
[[email protected] ~]# docker-compose ps第六步：查看日志信息
[[email protected] ~]# docker-compose logs第七步：关闭服务
[[email protected] ~]# docker-compose down 原文地址：https://blog.51cto.com/54dev/2462099
