Unix abstract sockets

This examples shows how to start a gRPC server listening on a unix abstract socket and how to get a gRPC client to connect to it.

What is a unix abstract socket

An abstract socket address is distinguished from a regular unix socket by the fact that the first byte of the address is a null byte ('\0'). The address has no connection with filesystem path names.

Try it

go run server/main.go

go run client/main.go

Explanation

The gRPC server in this example listens on an address starting with a null byte and the network is unix. The client uses the unix-abstract scheme with the endpoint set to the abstract unix socket address without the null byte. The unix resolver takes care of adding the null byte on the client. See https://github.com/grpc/grpc/blob/master/doc/naming.md for the more details.
