how to bind grpc client to specific network interface

[joe.p...@decisionsciencescorp.com]

Is it possible to pass a parameter to grpc that allows clients to pick a specific network interface on a computer with multiple ethernet interfaces?

What language?

Can grpc-go bind grpc client to specific network interface?

Sorry for the very late reply to this question.  Yes, this is possible in Go by providing a custom dialer to grpc: https://pkg.go.dev/google.golang.org/grpc#WithContextDialer

It would look something like:

myDialer := net.Dialer{LocalAddr: <your network interface address info here>}

client, err := grpc.Dial(target, <other options>,

  grpc.WithContextDialer(func(ctx context.Context, addr string) (net.Conn, error) {

    return myDialer.DialContext(ctx, "tcp", addr)

})
