I wrote this sample grpc server : https://github.com/chasehippen/grpc-server-test (some values removed for sensitivity) where I’ve tried to set up a tls server that will do client authentication using a set of certs that I’ve generated with a cert-manager “Certificate” resource. I’m trying to use the tls.crt, tls.key, and ca.crt files in my server and in my client.
