I'm trying to create Go gRPC-client code with this proto from the Nighthawk project and I'm getting this error:
user@computer:~/Code/nighthawk$ protoc --go_out=. --go_opt=paths=source_relative --go-grpc_out=. --go-grpc_opt=paths=source_relative api/client/output.proto

I see that these protos are defined in Envoy's repository here.
How do I import these so that I can generate the client code?
What is the command for this? Am I missing anything?
Generally you should not be building your own .pb.go files from other people's .proto files. Go will panic if multiple definitions of the same proto package are found in a single binary, so every .proto file published should ideally also provide .pb.go files in a central location. If that isn't the case for nighthawk, then you can still build that yourself. You'll need to download the Envoy dependencies and reference them via the -I parameter.
