The Full Stack Nanodegree course 4 project

Deploying a Flask API

This is the project starter repo for the fourth course in the Udacity Full Stack Nanodegree: Server Deployment, Containerization, and Testing.

In this project you will containerize and deploy a Flask API to a Kubernetes cluster using Docker, AWS EKS, CodePipeline, and CodeBuild.

The Flask app that will be used for this project consists of a simple API with three endpoints:

• GET '/': This is a simple health check, which returns the response 'Healthy'.
• POST '/auth': This takes a email and password as json arguments and returns a JWT based on a custom secret.
• GET '/contents': This requires a valid JWT, and returns the un-encrpyted contents of that token.

The app relies on a secret set as the environment variable JWT_SECRET to produce a JWT. The built-in Flask server is adequate for local development, but not production, so you will be using the production-ready Gunicorn server when deploying the app.

AWS Deployment

1) Stacks

The build of 3 stacks is successful:

1. CD Pipeline
2. Worker nodes
3. EKS cluster

2) Worker nodes "EC2 Instances"

3) EKS cluster

4) CD Pipeline

4) First sucessful build

5) Build failed

The build fails because one of the unit tests has failed.

6) EKS cluster is connected to kubectl

7 ) Postman tests

7.1) POST /auth

7.2) GET /contents
