Question

I am trying to run a PPTP VPN server in a Docker container. but when I do the command docker run pptpserver, or all different container I have tried, It will work but my cursor is just flashing and does not let me do any other command. I tried a super simple one, just copying test.sh in the container and run it, and it prints a confined times test, but I want a container that's in the background.

test.sh:
#/bin/bash
while :; do
  echo "test"
  sleep 2
done

The only way I can stop it is to stop the container in another terminal. Is there something I can do to just run a container like it shouts do, in the background.

为防止这种情况，您应该通过指定-d=true或仅使用-d选项以分离模式启动容器。如果未指定，则docker默认为前台模式，它将控制台附加到容器的标准输入，输出和标准错误中的进程，使其看起来好像您的终端在“挂起”。

所以尝试：

docker run -d pptpserver

您可以在Docker Run Reference文档中了解有关此行为的更多信息。
