gRPC in 3 minutes (Go)
BACKGROUND
For this sample, we've already generated the server and client stubs from helloworld.proto.
PREREQUISITES
- This requires Go 1.5 or later
- Requires that GOPATH is set
$ go help gopath
$ # ensure the PATH contains $GOPATH/bin
$ export PATH=$PATH:$GOPATH/bin
INSTALL
$ go get -u google.golang.org/grpc/examples/helloworld/greeter_client
$ go get -u google.golang.org/grpc/examples/helloworld/greeter_server
TRY IT!
- Run the server
$ greeter_server &
- Run the client
$ greeter_client
OPTIONAL - Rebuilding the generated code
1 First install protoc
- For now, this needs to be installed from source
- This is will change once proto3 is officially released
2 Install the protoc Go plugin.
$ go get -a github.com/golang/protobuf/protoc-gen-go
$
$ # from this dir; invoke protoc
$ protoc -I ./helloworld/helloworld/ ./helloworld/helloworld/helloworld.proto --go_out=plugins=grpc:helloworld
