启动两个nginx容器

编写docker-compose.yml

如果要编排的容器较多,建议使用目录将docker-compose.yml分隔开来

[root@localhost ~]# mkdir test
[root@localhost ~]# cd test/
[root@localhost test]# vim docker-compose.yml
nginx:
  container_name: nginx91
  image: nginx:latest
  ports:
    - "8091:80"
  volumes:
    - /www/wwwroot/8091:/usr/share/nginx/html
  hostname: nginx.test.com
#
nginx-php:
  container_name: nginx92
  image: nginx:latest
  ports:
    - "8092:80"
  volumes:
    - /www/wwwroot/8092/:/usr/share/nginx/html
  hostname: nginx-php.test.com
创建文件中volumes所制定的目录位置,并写入两个简单的页面
[root@localhost test]# mkdir /www/wwwroot/{8091,8092} -p
[root@localhost test]# echo "8091" >> /www/wwwroot/8091/index.html
[root@localhost test]# echo "8092" >> /www/wwwroot/8092/index.html

运行docker-compose文件

这些命令必须在存在docker-compose.yml文件的目录中执行,以下均是

[root@localhost test]# docker-compose up -d
Creating nginx91 ... done
Creating nginx92 ... done

文件中指定的镜像如果没有,会直接下载使用

查看启动的容器

[root@localhost test]# docker-compose ps
 Name           Command          State          Ports        
-------------------------------------------------------------
nginx91   nginx -g daemon off;   Up      0.0.0.0:8091->80/tcp
nginx92   nginx -g daemon off;   Up      0.0.0.0:8092->80/tcp

停止容器

[root@localhost test]# docker-compose stop 
Stopping nginx92 ... done
Stopping nginx91 ... done

启动容器

[root@localhost test]# docker-compose start
Starting nginx     ... done
Starting nginx-php ... done

删除容器

[root@localhost test]# docker-compose rm
Going to remove nginx92, nginx91
Are you sure? [yN] y
Removing nginx92 ... done
Removing nginx91 ... done

验证

可以访问映射的两个端口访问页面

[root@localhost test]# curl 192.168.1.14:8091
8091
[root@localost test]# curl 192.168.1.14:8092
8092
