🚨 Your Kubernetes pods are running wild – here's how to tame them

Most engineers know nodeSelector and affinity for attracting pods to nodes.

But what about repelling them?

Enter Taints & Tolerations – Kubernetes' bouncer system that keeps your workloads exactly where they belong.

🏢 Think of it like office security:

• Taints = "Authorized Personnel Only" signs on nodes • Tolerations = Security badges that grant pod access
• Scheduler = The security guard enforcing the rules

After watching countless teams struggle with Kubernetes deployments, I've learned that the tool isn't the problem—it's knowing when to evolve your strategy.

The Real Progression (Not What Marketing Says):​

Phase 1: Direct Helm (Weeks 1-4)

• Raw helm install commands
• Works for: 1-5 services, small teams
• Breaks when: Multiple environments hit

Starting with Kubernetes? We've all been there – copy-pasting YAML files and running kubectl apply until our fingers hurt. But here's the thing: raw Kubernetes YAML doesn't scale.

The Evolution Every Dev Team Goes Through:​

Stage 1: Raw YAML + kubectl "It works on my machine!"

Stage 2: Helm Charts "Finally, I can template my configs!"

Stage 3: GitOps + ArgoCD "My deployments are now bulletproof."
