Kubernetes in Production: What They Don’t Tell You

Why it works: Most pros know K8s basics—this dives into real-world challenges and solutions.
Subtopics:

• Real production outage war stories
• Node pressure, evictions, autoscaling pains
• Resource tuning (CPU/Mem/Pod limits)
• Monitoring beyond Prometheus & Grafana
• Readiness/Liveness vs startup probes
• Helm pitfalls and GitOps wins

💡 Add Live Demo: Chaos engineering with `kubectl` and `chaos-mesh`.

### ⚙️ 2. “Kubernetes at Scale: 1 Million Pods and 10,000 Nodes”

Why it works: Shows high-scale architecture and tuning—perfect for infra-heavy audiences.
Subtopics:

• etcd scaling and shard patterns
• kubelet optimizations, CRI tuning
• Cluster federation vs multi-cluster service mesh
• Use of CRDs to customize control plane
• Scaling logs/metrics/ingress

💡 Add Open-source Showcase: Show your infra-as-code Terraform/GitOps setup.

***

### 🔐 3. “Zero Trust Security in Kubernetes”

Why it works: Security is top priority; show real isolation models and best practices.
Subtopics:

• NetworkPolicies and Calico setup
• RBAC hardening (least privilege)
• Secrets management: HashiCorp Vault + K8s
• Zero trust service mesh (Istio/ZTunnel/Linkerd)
• Container image scanning (Trivy/Snyk)

💡 Live Attack Demo: Try a misconfigured pod → access cloud metadata, then fix.

***

### 🚀 4. “From Dev to Prod: Enterprise CI/CD with Kubernetes”

Why it works: DevOps folks love end-to-end automation.
Subtopics:

• Jenkins + ArgoCD + Helm flow
• Canary & Blue/Green deployments with Istio
• GitHub Actions + K8s deployment pipeline
• Secrets management in CI
• ChatOps and Slack deploy bots

💡 Live Deploy: Trigger code → GitHub Actions → ArgoCD deploy → verify in real-time.

### 🤖 5. “Kubernetes Operators: Automate Anything”

Why it works: Few people master Operators; it’s a hot area.
Subtopics:

• What’s an Operator vs Controller
• How to write one (Kubebuilder)
• Use case: Auto-scaling DB clusters, Backup jobs
• Watchers, Reconcilers, CRDs explained
• Real operator (e.g. Prometheus, Kafka)

💡 Live Demo: Build and deploy a mini custom Operator.
