How to use host's environment variables in the hostprocess container

[IndCheung]

I created a Flannel container using the hostprocess mode, but I found that after Flannel starts, it will call Powershell to execute some commands. However, the hostprocess container seems to not be able to share environment variables with the host, so executing the Powershell command in Flanneldexe reported an error. How do you solve this problem?

Note: I used the following base image to build the image: https://github.com/microsoft/windows-host-process-containers-base-image
