docker的常用命令（二）

容器的基本命令
有了鏡像纔可以玩容器，所以我們先下載一個容器，就下一個centos的吧~

docker pull centos

[root@dingqisui ~]# docker pull centos

創建一個容器並啓動ta

docker run -it centos /bin/bash

docker ps  # 列出容器

[root@dingqisui ~]# docker run -it centos /bin/bash
[root@2975eab5777c /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root@2975eab5777c /]# exit
exit
[root@dingqisui ~]# docker run -it centos /bin/bash
[root@0def9925d52c /]# ls
bin  dev  etc  home  lib  lib64  lost+found  media  mnt  opt  proc  root  run  sbin  srv  sys  tmp  usr  var
[root@0def9925d52c /]# [root@dingqisui ~]# 
[root@dingqisui ~]# docker ps -a # 列出當前正在運行的容器 還有你歷史運行過的

[root@dingqisui ~]# docker ps

exit是直接退出了
使用 ctrl + p +q ta還在後臺運行
刪除容器：

docker rm id
docker rm -f $(docker ps -aq)  刪所有

[root@dingqisui ~]# docker run -it centos /bin/bash
[root@6e43b7bdb03d /]# 
[root@6e43b7bdb03d /]# [root@dingqisui ~]# 
[root@dingqisui ~]# 
[root@dingqisui ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
6e43b7bdb03d        centos              "/bin/bash"         29 seconds ago      Up 28 seconds                           pensive_shtern
[root@dingqisui ~]# docker rm 6e43b7bdb03d
Error response from daemon: You cannot remove a running container 6e43b7bdb03d5bbae98316a632c346abdb8020a72c8eb0db27c7bcd13da0153c. Stop the container before attempting removal or force remove
[root@dingqisui ~]# docker stop 6e43b7bdb03d
6e43b7bdb03d
[root@dingqisui ~]# docker rm 6e43b7bdb03d
6e43b7bdb03d

啓動和停止容器：

docker start id 啓動
docker restart id 重啓
docker stop id  停止i
docker kill id 殺死
# 和Linux 基礎命令比較相似
