Tether provides a way for the control plane to send HTTP API requests to
services in data planes that runs in a remote datacenter without
requiring customers to open firewalls on their runtime plane.
public default StreamObserver<EgressResponse> egress(StreamObserver<EgressRequest> responseObserver)
Egress streams egress requests and responses. Logically, this is not
actually a streaming request, but uses streaming as a mechanism to flip
the client-server relationship of gRPC so that the server can act as a
client.
The listener, the RPC server, accepts connections from the dialer,
the RPC client.
The listener streams http requests and the dialer streams http responses.
