How to keep WIndows Container running?

I need to keep my Windows Container up so I can run further commands on it using docker exec.

On Linux, I'd start it to run either sleep infinity, or tail -f /dev/null. Alternatively, I could borrow pause.c from Kubernetes.

What does this look like on Windows?

Kubernetes on Windows used to use ping

cmd /c ping -t localhost

This would print lots of unnecessary output, so a good improvement should be

cmd /c ping -t localhost > NUL

What Kubernetes does now is to run a custom pauseloop.exe binary.

In late 2022, the current home for wincat/pauseloop is https://github.com/kubernetes/kubernetes/tree/master/build%2Fpause%2Fwindows%2Fwincat. The move was implemented in https://github.com/kubernetes-sigs/sig-windows-tools/pull/270.

A full run command would be:

docker run -d --name YourContainer mcr.microsoft.com/windows/nanoserver:1809 ping -t localhost

Note: Make sure 1809 is equal with your own windows version from [WIN]+[R] -> winver.

You should then be able to step into the running container instance with the name YourContainer:

docker exec -it YourContainer cmd

Use ping -t localhost will do it
