Docker退出容器不关闭容器
发布时间：2024-03-25 点击：130
进入docker容器后如果退出容器，容器就会变成exited的状态，那么如何退出容器让容器不关闭呢？
如果要正常退出不关闭容器，请按ctrl+p+q进行退出容器，这一点很重要，请牢记！
以下示例为退出容器但不关闭容器
[root@localhost ~]# docker attach c600c4519fc8 [root@c600c4519fc8 /]# exit exit [root@localhost ~]# docker ps -a container id image command created status ports names c600c4519fc8 centos /bin/bash 3 hours ago exited (0) 1 second ago pensive_jackson 5a7a0d694651 busybox sh 20 hours ago exited (0) 20 hours ago hungry_vaughan 4b0296d18849 hello-world /hello 46 hours ago exited (0) 46 hours ago hopeful_yonath [root@localhost ~]# docker start pensive_jackson pensive_jackson [root@localhost ~]# docker attach c600c4519fc8 ctrl + p + q [root@c600c4519fc8 /]# read escape sequence [root@localhost ~]# docker ps -a container id image command created status ports names c600c4519fc8 centos /bin/bash 3 hours ago up 22 seconds pensive_jackson 5a7a0d694651 busybox sh 20 hours ago exited (0) 20 hours ago hungry_vaughan 4b0296d18849 hello-world /hello 46 hours ago exited (0) 46 hours ago hopeful_yonath事实上我们可以在启动容器的时候就进行配置，加入-d参数来启动容器，当然，这条命令仅限于启动全新的容器，启动关闭的容器是不可以的。

docker run -d: 后台运行容器，并返回容器id
以下示例为使用docker -d启动容器并退出
[root@localhost ~]# docker run -i -t -d centos /bin/bash 8521b11d5d99535d4cb0080adc5a58a4dd018ecd0751d9945f7da7ab01bec330 [root@localhost ~]# docker ps -a container id image command created status ports names 8521b11d5d99 centos /bin/bash 4 seconds ago up 4 seconds eager_goldwasser c600c4519fc8 centos /bin/bash 3 hours ago exited (0) 28 seconds ago pensive_jackson 5a7a0d694651 busybox sh 20 hours ago exited (0) 20 hours ago hungry_vaughan 4b0296d18849 hello-world /hello 46 hours ago exited (0) 46 hours ago hopeful_yonath [root@localhost ~]# docker attach 8 [root@8521b11d5d99 /]# uname -r 3.10.0-514.el7.x86_64 [root@8521b11d5d99 /]# exit exit [root@localhost ~]# docker ps -a container id image command created status ports names 8521b11d5d99 centos /bin/bash 2 minutes ago exited (0) 2 seconds ago eager_goldwasser c600c4519fc8 centos /bin/bash 3 hours ago exited (0) 2 minutes ago pensive_jackson 5a7a0d694651 busybox sh 20 hours ago exited (0) 20 hours ago hungry_vaughan 4b0296d18849 hello-world /hello 46 hours ago exited (0) 46 hours ago hopeful_yonath 在这里你可能会发现，使用了-d的命令退出后容器依然还是死了，动手型的朋友可能会发现只是用docker run -d去启动容器也一样是死的
这里其实需要了解的是容器的运行机制，docker容器在后台运行，必须要有一个前台进程，这里我们让容器有前台程序运行，就可以实现容器的-d 启动后存活
[root@localhost ~]# docker ps -a container id image command created status ports names c600c4519fc8 centos /bin/bash 3 hours ago exited (0) 4 minutes ago pensive_jackson 5a7a0d694651 busybox sh 21 hours ago exited (0) 21 hours ago hungry_vaughan 4b0296d18849 hello-world /hello 47 hours ago exited (0) 47 hours ago hopeful_yonath [root@localhost ~]# docker run -d centos /bin/bash -c nohup ping -i 1000 www.baidu.com 8aa19c9604382bc019797ccda831ae1bcebd81d86380b6040d636e03000b440a [root@localhost ~]# docker ps -a container id image command created status ports names 8aa19c960438 centos /bin/bash -c 'nohup… 2 seconds ago up 2 seconds adoring_wing c600c4519fc8 centos /bin/bash 3 hours ago exited (0) 5 minutes ago pensive_jackson 5a7a0d694651 busybox sh 21 hours ago exited (0) 21 hours ago hungry_vaughan 4b0296d18849 hello-world /hello 47 hours ago exited (0) 47 hours ago hopeful_yonath我这里使用nohup在后台运行一个每1000秒ping一次百度的进程，另外你也可以使用”while true; do echo hello world; sleep 1; done”，无限输出hello world。
另外即便是有进程在后台运行，你进入了容器，输入exit退出，依然会终止容器的运行，请谨记。
ctrl+p+q依然是我认为的最佳用法。
