容器的使用（三）
一. 关联到一个正在运行的容器
1. 关联一个正在运行的容器
[root@c720120 ~]# docker container attach quotes
{"quote":"Sports don't define us it is not what we live for.","author":"Michael Wilbon","cat":"sports"}
{"quote":"I alone of English writers have consciously set myself to make music out of what I may call the sound of sense.","author":"Robert Frost","cat":"alone"}
2.从关联的容器中退出
（1）如果我们想退出且不停止该容器的，使用【Ctrl +P 】【Ctrl +Q】
（2）如果退出容器而又停止容器，使用【Ctrl +C】
3. 使用案例
（1）运行一个容器
[root@c720120 ~]# docker run -d --name nginx -p 8080:80 nginx:alpine
8eb5842359a3ab073ce4ab1b9a49f6d6dad3c2e617a6462cb6a2b89704932ac6
（2）在另一个LINUX容器请求访问
[root@c720120 ~]# curl -4 localhost:8080
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
body {

margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif;
}
</style>
</head>
<body>

working. Further configuration is required.</p><p>For online documentation and support please refer to

</body>
</html>
（3）关联到nginx的终端
[root@c720120 ~]# docker container attach nginx
(4) 在linux的另一个终端请求访问
[root@c720120 ~]# for n in {1..10}; do curl -4 localhost:8080; done

（5）看下关联容器的输出信息
[root@c720120 ~]# docker container attach nginx
172.17.0.1 - - [05/Jun/2018:13:00:10 +0000] "GET / HTTP/1.1" 200 612 "-" "curl/7.29.0" "-"

（6）删除我们刚才运行的容器，实验结束、
[root@c720120 ~]# docker container rm -f nginx
nginx
