#Kubernetes

Kubernetes looks overwhelming at first glance. This post breaks down what Pods, ReplicaSets, Deployments, Services, Ingress, ConfigMaps, and Secrets actually do and how they connect — with practical YAML examples and local dev setup.

I adopted Kubernetes (k8s) blindly because it was 'trendy' and 'scalable'. The result? A massive infrastructure bill and YAML hell. I share my honest retrospective on the dangers of over-engineering and when you should actually use Kubernetes.

Stop running `kubectl apply` manually. We explain GitOps, where Git becomes the Single Source of Truth for your infrastructure. Learn the difference between Push vs Pull deployments, how tools like ArgoCD automate synchronization, strategies for handling secrets in Git, and how to detect when someone manually changes your cluster configuration (Drift).

Solving server waste at dawn and crashes at lunch. Understanding Auto Scaling vs Serverless through 'Taxi Dispatch' and 'Pizza Delivery' analogies. Plus, cost-saving tips using Spot Instances.

Why is it called 'Canary'? How does it differ from Rolling and Blue/Green deployments? We explore the strategy of releasing to a small subset (1%) of users first to detect issues before they impact everyone. Includes details on Metrics, Tools, and advanced strategies.

How to deploy without shutting down servers. Differences between Rolling, Canary, and Blue-Green. Deep dive into Database Rollback strategies, Online Schema Changes, AWS CodeDeploy integration, and Feature Toggles.
