I am unable to properly mount volumes using HostPath within Kubernetes running in Docker and WSL 2. This seems to be a WSL 2 issue when mounting volumes in Kubernetes running in Docker. Anyone know how to fix this?
Here are the steps:
Deploy debug build to Kubernetes for my app. Attach Visual Studio Code using the Kubernetes extension Navigate to the project folder for my application that was attached using the volume mount <= Problem Right Here
When you go and look at the volume mount nothing is there.
C:\Windows\System32>wsl -l -v
