Learn how to build, test, and deploy microservices powered by Docker, Flask, and React!
In this course, you will learn how to quickly spin up a reproducible development environment with Docker to manage a number of microservices. Once the app is up and running locally, you’ll learn how to deploy it to an Amazon EC2 instance. Finally, we’ll look at scaling the services on Amazon EC2 Container Service (ECS) and adding AWS Lambda.
We’ll also be practicing test-driven development (TDD), writing tests first when it makes sense to do so. The focus will be on server-side unit, functional, and integration tests along with end-to-end tests to ensure the entire system works as expected.

Check out the live app, running on a cluster of EC2 instances:
In this first part, you’ll learn how to quickly spin up a reproducible development environment with Docker to create a RESTful API powered by Python, Postgres, and the Flask web framework. After the app is up and running locally, you’ll learn how to deploy it to an Amazon EC2 instance.
Tools and Technologies: Python, Flask, Flask-SQLAlchemy, Flask-Testing, Gunicorn, Nginx, Docker, Docker Compose, Docker Machine, Postgres, Flask Blueprints, Jinja Templates
Tools and Technologies: Code Coverage with Coverage.py, continuous integration (CI), Node, NPM, Create React App, React, Enzyme, Jest, Axios, Flask-CORS, React forms, Flask Debug Toolbar
In part 3, we’ll add database migrations along with password hashing in order to implement token-based authentication to the users service with JSON Web Tokens (JWTs). We’ll then turn our attention to the client-side and add React Router to the React app to enable client-side routing along with client-side authentication.
Tools and Technologies: Flask-Migrate, Flask-Bcrypt, PyJWT, react-router-dom, Bulma, React Authentication and Authorization
In part 4, we’ll add end-to-end (e2e) tests with Cypress, form validation to the React app, a Swagger service to document the API, and deal with some tech debt. We’ll also set up a staging environment to test on before the app goes into production.
Tools and Technologies: Cypress, Swagger UI
In part 5, we’ll dive into container orchestration with Amazon ECS as we move our staging and production environments to a more scalable infrastructure. We’ll also add Amazon’s Elastic Container Registry along with Elastic Load Balancing for load balancing and Relational Database Service (RDS) for data persistence.
Tools and Technologies: AWS, EC2, Elastic Container Registry (ECR), Elastic Container Service (ECS), Elastic Load Balancing (ELB), Application Load Balancer (ALB), Relational Database Service (RDS)
In part 6, we’ll focus our attention on adding a new Flask service, with two RESTful-resources, to evaluate user-submitted code. Along the way, we’ll tie in AWS Lambda and API Gateway and spend a bit of time refactoring React and the end-to-end test suite. Finally, we’ll update the staging and production environments on ECS.
Tools and Technologies: AWS Lambda and API Gateway
In part 7, we’ll refactor the AWS Lambda function to make it dynamic so it can be used with more than one exercise, introduce type checking on the client-side with React PropTypes, and update a number of components. We’ll also introduce another new Flask service to manage scores. Again, we’ll update the staging and production environments on ECS.
Tools and Technologies: AWS Lambda and ECS, PropTypes, and Flask
