I have multiple docker containers running various GRPC servers. Currently I start these servers like this:

   server.bind('0.0.0.0:50051',grpc.ServerCredentials.createInsecure());

Obviously this created a grpc server that is not user ssl.

For my public facing API gateway I am using lets encrypt to generate SSL certificates. Is there a way I can do the same for my downstream containers?

Note: I am using kubernetes so my certificates are automatically provisioned and managed by Kube-Lego
