grpc-microservice

A dummy microservice system using grpc to communicate within services. Use Docker Compose to deploy these services

There are two microservices

1. user-service
   • do the user authentication and provide a jwt token
2. order-service
   • save orders and give saved orders
   • to use these services user need to be authenticated
   • so initially user need to be logged in using login url and get the jwt token
   • send the jwt token with consecutive requests

Using Grpc to communicate between these two services

Docker Compose

• Using docker to put these services (and needed mysql dbs) into containers and use Docker Compose to connect these containers together
• Use docker compose up to start the services
• Use docker compose down to stop the services
• Use `docker scale = n to scale up/down containers
  • docker compose scale user-service=n will create n number of user-service containers
  • docker compose scale order-service=n will create n number of order-service containers
