執行一個新的容器

[root@localhost~]# docker run -i -t centos /bin/bash

[root@bd1a482d44f5 /]#

引數解釋
-i, --interactive               Keep STDIN open even if not attached

-t, --tty                            Allocate a pseudo-TTY

PS：“[root@bd1a482d44f5 /]#” 這行出現證明已進入容器

退出容器

[root@localhost~]# exit

exit

檢視執行的容器

[root@localhost~]# docker ps

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

檢視全部容器列表

[root@localhost~]# docker ps -a

CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES

啟動，停止，重啟容器

[root@localhost~]# docker start thirsty_stallman    /啟動名字為thirsty_stallman的容器
[root@localhost~]# docker stop thirsty_stallman        /停止名字為thirsty_stallman的容器
[root@localhost~]# docker restart thirsty_stallman    /重啟名字為thirsty_stallman的容器

---

重新命名容器的名字

[root@localhost~]# docker rename nauseous_ardinghelli controller      /將容器名字為nauseous_ardinghelli更改成controller

進入與容器的互動模式

[root@localhost~]# docker attach nauseous_ardinghelli

[root@48a415dde98a ~]#

簡單一點來說

就是先

 

 docker ps -a        查詢映象id

 docker commit  id   woshihaioyong168/contos (庫)

 docker login （登入一下）

 docker images      檢視一樣狀態

 docker push  woshihaiyong168/centos

完成！！
