HTTP, HTTP/2, and gRPC Proxying

Linkerd can proxy all TCP connections, and will automatically enable advanced features (including metrics, load balancing, retries, and more) for HTTP, HTTP/2, and gRPC connections. (See TCP Proxying and Protocol Detection for details of how this detection happens).

Notes

• gRPC applications that use grpc-go must use version 1.3 or later due to a bug in earlier versions.
• gRPC applications that use @grpc/grpc-js must use version 1.1.0 or later due to a bug in earlier versions.
