@kangjk1017 do you have the ability pull, build & test the PR to see if it works on your windows nodes?

@0xaravindh and I do not have the ability to test on windows nodes. However, a fetch of this branch, local build, & push to a non-public artifact registry has a manifest with os.version for windows:

Thank you very much. It works perfectly.
I was able to run containers on both Linux and Windows nodes using the sidecar image us-docker.pkg.dev/agones-images/ci/agones-sdk:1.48.0-dev-1ebe0d9.
Unfortunately, aside from using this built image, I’m in a difficult position to test anything else on my own.

Thank you again so much for all your work.
