does not work with Windows namedpipe as proxy

[azyshalom]

using csi-grpc-proxy-v0.5.2-windows-amd64.exe from
https://github.com/democratic-csi/csi-grpc-proxy/releases/download/v0.5.2/csi-grpc-proxy-v0.5.2-windows-amd64.exe

it looks like the issue is in http2 code that add :80 suffix
_2023/08/13 06:09:52 http2: Transport failed to get client conn for localhost:80: The pipe has been ended.

which comes from:
https://github.com/golang/net/blob/c8c0290b421c479315f66c7b68b617ef6e73c668/http2/transport.go#L560

where a few line before, function authorityAddr return address + port:
https://github.com/golang/net/blob/c8c0290b421c479315f66c7b68b617ef6e73c668/http2/transport.go#L519

same error with version 0.5.3 from https://github.com/democratic-csi/csi-grpc-proxy/releases/download/v0.5.3/csi-grpc-proxy-v0.5.3-windows-amd64.exe

[travisghansen]

Hmm I’ll take a look.

Out of curiosity it looks like containerd/crictl support tcp directly, why do you need the proxy?

[azyshalom]

Thanks, gRPC in C++ does not support named pipes, therefore im looking for tcp<=>namedpipe generic reverse proxy

[travisghansen]

This should do it. I’ll see if I can get containerd running on my windows dev machine and try out your use-case.
