This series documents my journey deploying a Python and Redis chat application from scratch to a live Kubernetes cluster on AWS. It covers the full DevOps lifecycle: local development pain points, containerisation with Docker, automated CI/CD pipelines, and finally cloud deployment on EKS.
What You’ll Learn
- Part 1: Local Development – The manual way of running the app, highlighting dependency hell and the “it works on my machine” problem
- Part 2: Docker Containerisation – Packaging the app and Redis into isolated, portable containers
- Part 3: CI/CD with GitHub Actions – Automating image builds and pushes to AWS ECR
- Part 4: Live EKS Deployment – Deploying to a serverless Kubernetes cluster with Fargate and load balancing
Let’s get started here.
