Microservice architecture based on SpringBoot, written in Kotlin.

Attempting to design as a "Twelve-Factor App", but using a root-POM as done in the course.

1. Check out jOOQ with seek() for easier implementation of keyset/seek pagination

• ./build-and-start
  • Rebuilds all .jar files and Docker images
  • Starts the project locally
• ./start-dev
  • Used for local development
  • Starts all supporting services as Docker images

Use 'chmod +x ./SCRIPT_NAME' if permission is denied.

Use the script ./start-dev in the root folder to start all backing services (databases, Redis etc.).

Used as the entrypoint for the microservices. Exposed on port 8080 and redirects requests to the correct service based on URL paths.

Authentication service that stores usernames and hashed passwords in the connected database. Uses Redis to store active sessions so other services can verify requests that require authentication, and messages the other services via RabbitMQ on creation of new accounts.

• PostgreSQL database for persistent storage.
• Consul as discovery service.
• Redis for storing active sessions.
• RabbitMQ as message-broker.
  • Uses the service.action.exchangetype naming scheme for exchanges, e.g. user.created.fx for a fanout-exchange ('fx') used when new users are created.
