Debian主机: CTRL +P+Q不能使容器存活
Debian主机: CTRL +P+Q不能使容器存活
提问于 2016-02-11 11:20:43
我正在跟踪Docker网站上的自定节奏视频教程：https://training.docker.com/self-paced-training
在第一段视频中，导师讨论了拆船坞的问题，同时还保留了集装箱的生命。显示的示例是运行：
docker run -i -d ubuntu:latest /bin/bash然后，在创建容器时，用以下方式退出：
CTRL + P + Q这似乎不适合我。我注意到导师在用Windows和Putty。我在我的Debian开发机器上使用了docker，所以我不确定用于分离的命令是否不同。
当我按下上面的键组合时，它从容器中退出，但正在运行：
ps -ef..。没有显示任何容器。这是我的输出：

我并不100%肯定您的本地env是如何设置的，但是如果您在同一台机器上运行该ps -ef，则可能会有一些/bin/bash是您的容器。
当你用序列分离一个容器时，它不会杀死你的容器，它会分离。为了重新掌握它，您可以运行docker attach <container name or container id>。
然而，即使我没有看培训录像，你的例子是错误的。您启动一个已经分离的容器(使用docker run -d)，因此如果您试图在之后分离，它将不会影响对接。
为了启动附加的容器以便以后可以分离，您应该使用docker run -i -t ubuntu:latest /bin/bash。
当使用-d启动容器时，对接者应该向您显示结果ID，然后可以附加到这个ID上，然后用键顺序分离。
ID=$(docker -i -d ubuntu:latest /bin/bash)
# We are not in docker, still on our shell
docker attach $ID
# We are now attached to the container
# Exectute Ctrl-p Ctrl-Q
# The container is now detached and we are back to our shell页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
