Volume mounts not working Kubernetes and WSL 2 and Docker

According to the following thread, hostPath volumes are not officially supported for wsl2, yet. They do suggest a workaround, though I had trouble getting it to work. I have found that prepending /run/desktop/mnt/host/c seems to work for me.

// C:\someDir\volumeDirhostPath:  path: /run/desktop/mnt/host/c/someDir/volumeDir  type: DirectoryOrCreate

Suggested workaround from thread: https://github.com/docker/for-win/issues/5325#issuecomment-567594291

Using @RyanDarnell's excellent answer above, here is what worked for me

Objective: get message-db with password using docker build --secret running in local docker-desktop kubernetes with StatefulSet and StorageClass using Skaffold
