容器基本操作：

建立一個容器

 [[email protected] ~]# docker run -itd ubuntu
 3635f4dd3ae30a4377fc4f2eafc191b7890bbe5873bb4e5f9e5077f794466ec4

檢視容器程序

 [[email protected] ~]# docker ps 
 CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
 3635f4dd3ae3        ubuntu              "/bin/bash"         8 seconds ago       Up 6 seconds                            romantic_lamarr
 [
 
[email protected] ~]# docker ps -l
 CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
 3635f4dd3ae3        ubuntu              "/bin/bash"         15 seconds ago      Up 13 seconds                           romantic_lamarr
 [
 
[email protected] ~]# docker ps -a
 CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
 3635f4dd3ae3        ubuntu              "/bin/bash"         About a minute ago   Up About a minute   

開啟容器：

 [[email protected]
 
 ~]# docker start  romantic_lamarr
 romantic_lamarr

進入容器進行操作：

 [[email protected] ~]# docker attach romantic_lamarr
 [email protected]:/# ls
 bin   dev  home  lib64  mnt  proc  run   srv  tmp  var
 boot  etc  lib   media  opt  root  sbin  sys  usr
 [email protected]:/# exit
 exit

停止容器

 [[email protected] ~]# docker stop romantic_lamarr
 romantic_lamarr

刪除容器

 [[email protected] ~]# docker rm romantic_lamarr
 romantic_lamarr
 [[email protected] ~]# docker start romantic_lamarr
 Error response from daemon: No such container: romantic_lamarr
 Error: failed to start containers: romantic_lamarr

PS：使用rm需要先停止使用容器（stop），強行刪除可以加 -r 引數選項

重新命名容器

 [[email protected] ~]# docker run -itd ubuntu
 992dec8c882cbc3115045be8d7e76b496733e5996e4e083aebaa00e1ccef2a23
 [[email protected] ~]# docker ps
 CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
 992dec8c882c        ubuntu              "/bin/bash"         5 seconds ago       Up 3 seconds                            reverent_hamilton
 [[email protected] ~]# docker rename reverent_hamilton jinc
 [[email protected] ~]# docker ps
 CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
 992dec8c882c        ubuntu              "/bin/bash"         22 seconds ago      Up 21 seconds                           jinc
