docker-compose-email-sender-system

Project Description

The user can access the "frontend" service through http://localhost. The form submition is redirected by NGINX to the Python backend application.

The backend "app" service connects to the Postgres "db" service and inserts the email data content (subject and message) into the emails table. Moreover, the "app" service sends the email to the queue application.

The Redis "queue" service receives the emails from the backend and just temporary stores the emails that are consumped by the workers applications.

The Python "worker" service simulates the enqueued emails consumption from *"queue" * service and do some prints in the container logs. This service is horizontally scaled, so it's possible to see during the project execution 3 workers being instantiated.
