骑猪看日落 2022-02-17 12:09 222阅读 0赞

## 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
    dc7b94b3c0d4        johncarnell/tmx-simple-service:chapter1   "/bin/sh -c ./run.sh"    2 hours ago         Up 2 hours          0.0.0.0:8080->8080/tcp              johncarnell-dachao
    
    # 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
    CONTAINER ID        IMAGE                                     COMMAND                  CREATED             STATUS                PORTS                               NAMES
    dc7b94b3c0d4        johncarnell/tmx-simple-service:chapter1   "/bin/sh -c ./run.sh"    2 hours ago         Up 2 hours (Paused)   0.0.0.0:8080->8080/tcp              johncarnell-dachao
    
    # 取消当前容器的暂停进程操作
    [root@giraffe-dachao microservice]# docker unpause johncarnell-dachao
    johncarnell-dachao
