Microservice based example web backend

An example of microservice-based and docker-containerized web backend app

Services:

• Product Service (FastAPI,PostgreSQL)
• Order Service (FastAPI,PostgreSQL)

Run:

• Run docker-compose up -d (or sudo docker-compose up -d) in the main app directory
• App will start only after the databases have been created,after few seconds or so if they havent been (if there are no db service volumes)
• Product Service is on port 8002 -- Product Service Docs
• Order Service is on port 8001 -- Order Service Docs

Migrations:

• Alembic migration tool used for product and order services
• Adding new migration script: (sudo) docker-compose run <servicename (product_service,order_service)> alembic revision --autogenerate -m "<filename>"
• Running migrations : (sudo) docker-compose run <servicename (product_service,order_service)> alembic upgrade head

TODO:

• Authentication
• More services with different frameworks and databases
• Communication between services where necessary (example:updating product quantity when order is made)
