FastAPI Tutorial Series

Welcome to the FastAPI & Kubernetes Tutorial Series with PyCharm & AWS EKS.

Prerequisites

Before starting up this project, make sure you have an AWS account and PyCharm installed in your machine.

• In this tutorial we will be using PyCharm Professional.

Software Installation

• AWS Command Line Interface - The AWS Command Line Interface (CLI) is a unified tool to manage your AWS services.

• eksctl - The official CLI for Amazon EKS

• Kubernetes - also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications.

• Helm - The package manager for Kubernetes. Helm helps you manage Kubernetes applications — Helm Charts help you define, install, and upgrade even the most complex Kubernetes application.

• PostgreSQL - The World's Most Advanced Open Source Relational Database

• Redis - open source (BSD licensed), in-memory data structure store, used as a database, cache, and message broker

• NICE DCV (Optional) - Deliver high-performance remote desktop and application streaming. If you are interested to run your workload directly in AWS.

System Dependencies
