#Golang gRPC mongoDB example

How to run mongoDB and application

• docker-compose build --no-cache
• docker-compose up -d
• docker-compose ps
• docker-compose logs -f {service-name}
• import internal/proto/vacancy.proto file into new Postman gRPC Request and apply CRUD methods of gRPC (category, city, vacancy)

---

GUI

• visit http://localhost:8081/ - MongoExpress (GUI for MongoDB)
• visit http://localhost:9000/ - Portainer (GUI for docker containers)

Windows installation of the protoc compiler

• Download protoc https://github.com/protocolbuffers/protobuf/releases
• Add to System variables https://www.geeksforgeeks.org/how-to-install-protocol-buffers-on-windows/
• go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
• go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
• After run commands above, open your $GOPATH$/bin directory and there should be 2 new exe files (protoc-gen-go.exe and protoc-gen-go-grpc.exe)
• If commands above is not clear , visit https://stackoverflow.com/questions/70642919/installing-grpc-in-windows
• After if you want to generate go files of .proto definition run commands below (from Protobuf/protoc commands section from this file)
