补充知识：一张图看懂docker容器的所有状态

%小知识：docker容器状态的转换实现-1猿站网-插图

部分解释：

创建容器的命令

run 是create和start的结合

create-created-start

例子：

docker create httpd

OCM硬件信息

docker kill id 强制关闭容器

die某个程序别强制退出，或者进程出错

docker pause :暂停容器中所有的进程。

docker unpause :恢复容器中所有的进程。

以上这篇docker容器状态的转换实现就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
