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

Phase 2: GitOps + CI/CD (Months 2-6)

  • Git becomes source of truth
  • CI/CD still handles deployment
  • Works until: Manual oversight becomes the bottleneck

Phase 3: ArgoCD + Full GitOps (Month 6+)

  • Pull-based reconciliation
  • Self-healing deployments
  • The endgame for operational scale

The Harsh Truths Nobody Talks About:​

❌ Don't start with ArgoCD – I've seen teams waste months on premature GitOps

❌ Chart dependencies are nightmare fuel – Keep them simple or suffer debugging hell

❌ Your GitOps repo becomes a single point of failure – Plan disaster recovery early

✅ 10+ services = Helm templating becomes mandatory

✅ The "Application of Applications" pattern saves sanity at 20+ services

✅ Pull-based deployment eliminates credential sprawl

The Repository Structure That Scales:​

infrastructure-repo/
├── clusters/           # Different change frequency
├── applications/       # Service-specific configs  
└── shared/            # Reusable components

Pro Tips from Production Battle Scars:​

🔧 Always use helm template before deploying – Template errors are cryptic

🔐 Never commit secrets to Git – Use Sealed Secrets or External Secrets Operator

📊 Monitor ArgoCD apps like infrastructure – They ARE your infrastructure

🚨 The "manual kubectl fix" breaks everything – Respect the GitOps contract

The Real Question:​

It's not "What's the best tool?" It's "What's the right complexity for our operational maturity?"

Sometimes that's just Helm. And that's perfectly fine.

The best deployment strategy is the one your team can operate reliably in production, not the one that wins conference talks.
