go-user-service

This module manages the storage of the refresh tokens.

Requires a valid refresh token, cannot generate one itself.

Before all

• Have Go
• Have gRPC
• Have Docker

installed.

gRPC settings

Everything starts with designing the protobuf file (./proto/token.proto for this project) and once the messages and services are designed (or changed later) the following command should be run:

cd $GOPATH/src/github.com/vahdet/go-auth-service
protoc -I proto proto/auth.proto --go_out=plugins=grpc:proto

Calling the other services from the code

We need to make gRPC calls from the code to containers stemming from go-user-store and go-refresh-token-store images. To do that we can use Kubernetes client API

This command will generate (or recreate if it exists) a .pb.go file just beside itself. It is ./proto/auth.pb.go here and it allows implementing Go services, repositories, in short any Go code behind the services defined in the .proto file.

For this case, the server implementation is performed in ./grpcserver/server.go file.

Git Tips for humble beings

The StackOverflow answer resembles three lines of general purpose git commands that can be used anytime a change is made and should be committed to master branch:

git add .
git commit -a -m "My classical message to be replaced"
git push
