Kubectl: get a shell to a running container under Windows

I'm trying to log into running container using Kubectl, according to instructions in https://kubernetes.io/docs/tasks/debug-application-cluster/get-shell-running-container/, but I'm failing miserably:

kubectl exec -it mycontainer -- /bin/bash

Unable to use a TTY - input is not a terminal or the right kind of file rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"D:/Applications/Git/usr/bin/bash\": stat D:/Applications/Git/usr/bin/bash: no such file or directory"

command terminated with exit code 126

It looks like kubectl tries to exec bash on my machine, which is totally not what I want to achieve.

I can exec commands without spaces: 

$ kubectl exec mycontainer 'ls'
lib
start.sh

But with not:

$ kubectl exec mycontainer 'ls .'
rpc error: code = 2 desc = oci runtime error: exec failed: container_linux.go:247: starting container process caused "exec: \"ls .\": executable file not found in $PATH"

command terminated with exit code 126

What I'm doing wrong?

I've tried both in mingw git shell , as with plain windows console.

kubectl shell windows

Seems it might be related to this github issue.

One of the workarounds might be to use winpty as specified here.
winpty kubectl.exe exec -it pod-name -- sh

You can also try /bin/sh instead of /bin/bash it worked for me, but I do not have a Windows machine to check it in the same environment as you.

Below command worked for me to launch windows command prompt

kubectl exec -it mycontainer -- cmd.exe
