🚀 DevOps Mini-Project: Go + Redis on Kubernetes (From Scratch)

Last week I built a small but real DevOps project to practice end-to-end Kubernetes workflows — from code to cluster.

What’s the project?A simple Go web service that counts visits using Redis, deployed on a local Kubernetes cluster (MicroK8s) and packaged as a Helm chart.

🧩 What’s inside

Go app with health & visit endpoints
Redis for state (visitor counter)
Docker image for the app
Kubernetes manifests (initially)
Helm chart (final state)
Ingress to expose the app via a hostname👉 http://go-app.local/visits

⚙️ What I focused on (DevOps lessons)

Turning raw YAML into a reusable Helm chart
Adding liveness & readiness probes for safe deploys
Using Ingress instead of NodePort hacks
Debugging real issues: disk pressure, pod evictions, networking
Making everything reproducible, not “works on my machine”

🔁 How you can reproduce it

Clone the repo👉 https://github.com/Griffindeetox/go-redis-k8s-lab
Start MicroK8s
Install the app with one command: microk8s helm3 install go-redis-app ./helm/go-redis-app -n go-redis-app --create-namespace
Add go-app.local to /etc/hosts
Hit:curl http://go-app.local/visits

🧠 Why this matters

This isn’t about fancy tools — it’s about thinking like a DevOps engineer:
