Windows host process default path is showing as c:\ instead of c:\hpc on AKS cluster version 1.28.5

[anilkumar1619]

Hello Team,

I am trying to deploy windows host process for containers by following below document and when checked, I noticed the default exec path in the container is showing as c:\ instead of c:\hpc.

https://learn.microsoft.com/en-us/azure/aks/use-windows-hpc

This is working as expected in 1.27.x whereas it is incorrect in 1.28.5. In 1.28.x container, $env.CONTAINER_SANDBOX_MOUNT_POINT is set to c:\hpc but while connecting it is by default taking to c:\

As per below Github issues and the document it says C:\hpc is the right path.

https://github.com/kubernetes/enhancements/tree/master/keps/sig-windows/1981-windows-privileged-container-support#container-mounts

Below are the screenshots for reference.

Left, 1.27.9, default working folder is expected C:\C:{container-id} which is correct.
Right, 1.28.5, default working folder is supposed to be C:\hpc but it turns out to be C:\ instead.

Kindly check and assist if this is expected or not.

Workaround: Switch the working directory to $env:CONTAINER_SANDBOX_MOUNT_POINT before running the commands
Will be fixed in containerd/containerd#10069
