 第三种：exec方式，终端时分开的，推荐
 [root@web1 overlay2]# docker exec -it mynginx sh#### lsbin boot dev etc home lib lib64 media mnt opt proc root run sbin srv sys tmp usr var# exit[root@web1 overlay2]#[root@web1 overlay2]#[root@web1 overlay2]#[root@web1 overlay2]# docker padocker: 'pa' is not a docker command.See 'docker --help'[root@web1 overlay2]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES6fc2d091cfe9 nginx "nginx -g 'daemon ..." 45 seconds ago Up 43 seconds 80/tcp mynginxac46c019b800 alpine "/bin/sh" 16 minutes ago Up 16 minutes test1
 
12、查看docker进程及删除容器上面已经演示：
 [root@web1 overlay2]# docker psCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES9fc796e928d7 nginx "sh" 2 minutes ago Up 8 seconds 80/tcp mynginxac46c019b800 alpine "/bin/sh" 12 minutes ago Up 12 minutes test1
  [root@web1 overlay2]# docker ps -a #-a :显示所有的容器，包括未运行的CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES9fc796e928d7 nginx "sh" 4 minutes ago Exited (0) About a minute ago mynginxac46c019b800 alpine "/bin/sh" 15 minutes ago Up 15 minutes test13bf234febeaa alpine "sh" 17 minutes ago Exited (0) 16 minutes ago youthful_lumiereab113c63f0b4 centos "echo 'hello world'" 31 minutes ago Exited (0) 31 minutes ago infallible_torvaldsb326027dcf42 zxg/my_nginx "nginx" 8 days ago Exited (0) 8 days ago my_nginx4f1f1ca319f2 centos "bash" 8 days ago Exited (137) 8 days ago musing_lichterman64b4e32991c7 nginx "nginx -g 'daemon ..." 12 days ago Exited (0) 12 days ago mynginx1aee506fe7b5a alpine "sh" 12 days ago Created infallible_haibt70620c73b9a0 alpine "sh" 12 days ago Created gallant_volhard7655cbf87bb0 alpine "sh" 12 days ago Created agitated_brahmagupta33fb949372e8 fce289e99eb9 "/hello" 12 days ago Created elastic_dijkstra9de47616aea4 fce289e99eb9 "/hello" 13 days ago Created confident_fermi[root@web1 overlay2]# docker rm 9fc796e928d7 #rm时删除一个或多个容器9fc796e928d7
  
13、查看容器详细信息并不需要进入到容器里面，通过查看详细信息看到了刚才运行的nginx，宿主机curl ip地址访问一下运行情况 。
  [root@web1 overlay2]# docker inspect mynginx[ { "Id": "6fc2d091cfe9b0484da3e70db842446bbdfeb7f5e5409c2e40ae21b99498d010", "Created": "2019-08-07T08:57:48.864538933Z", "Path": "nginx", "Args": [ "-g", "daemon off;"], "State": { "Status": "running", "Running": true, "Paused": false, "Restarting": false, "OOMKilled": false, "Dead": false, "Pid": 119948, "ExitCode": 0, "Error": "", "StartedAt": "2019-08-07T08:57:49.417992182Z", "FinishedAt": "0001-01-01T00:00:00Z" }, "Image": "sha256:e445ab08b2be8b178655b714f89e5db9504f67defd5c7408a00bade679a50d44", "ResolvConfPath": "/var/lib/docker/containers/6fc2d091cfe9b0484da3e70db842446bbdfeb7f5e5409c2e40ae21b99498d010/resolv.conf", "HostnamePath": "/var/lib/docker/containers/6fc2d091cfe9b0484da3e70db842446bbdfeb7f5e5409c2e40ae21b99498d010/hostname", "HostsPath": "/var/lib/docker/containers/6fc2d091cfe9b0484da3e70db842446bbdfeb7f5e5409c2e40ae21b99498d010/hosts", "LogPath": "", "Name": "/mynginx", "RestartCount": 0, "Driver": "overlay2", "MountLabel": "", "ProcessLabel": "", "AppArmorProfile": "", "ExecIDs": , "HostConfig": { "Binds": , "ContainerIDFile": "", "LogConfig": { "Type": "journald", "Config": {} }, "NetworkMode": "default", "PortBindings": {}, "RestartPolicy": { "Name": "no", "Ma
