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.
