Docker命令之pause和unpause

应用场景

暂停一个或多个容器中的所有进程

使用

docker pause CONTAINER [CONTAINER...]

docker unpause CONTAINER [CONTAINER...]

说明

`docker compose `命令可以挂起指定容器中的所有进程，而不是关闭当前容器。

案例代码

# 先查看当前运行的容器
[root@giraffe-dachao microservice]# docker ps
CONTAINER ID        IMAGE                                     COMMAND                  CREATED             STATUS              PORTS                               NAMES

# 对当前的容器进行暂停进程操作 
[root@giraffe-dachao microservice]# docker pause johncarnell-dachao
johncarnell-dachao
# 查看当前容器中STATUS总添加了pause
[root@giraffe-dachao microservice]# docker ps
