bithavoc / hellogrpcstdin

An example of GRPC Dialing with os.Stdin and os.Stdout of a child process.

GRPC external plugin example

go get github.com/bithavoc/hellogrpcstdin

An example of GRPC Dialing with Stdin and Stdout of a child process.

greeter_server launches greeter_client as a process and uses os.Stdin and os.Stdout to listen for GRPC requests.

Note: You don't really need this library to implement GRPC plugins in Go, you can always use hashicorp/go-plugin which uses unix sockets.

Running Example

Compile Client(Plugin):

(cd greeter_client; go build)

Compile Server(Plugin):

(cd greeter_server; go build)

Run Server(Plugin):

(cd greeter_server; ./greeter_server)

You should see an output similar to this:

Server starting

agent process running, will ready listener
accepting, only conn ready
