Kubernetes Production Patterns

Master production-grade Kubernetes with architecture patterns, deployment strategies, networking, storage, security, monitoring, and operational best practices for enterprise environments.

Kubernetes Fundamentals

start here: no prior Kubernetes knowledge needed

  • Kubernetes Architecture

    control plane, worker nodes, etcd, API server, scheduler, controller manager

    →
  • Kubernetes Objects

    pods, services, deployments, statefulsets, daemonsets, jobs, cronjobs

    →
  • Cluster Setup & Management

    kubeadm, managed clusters (EKS, GKE, AKS), cluster administration

    →

Architecture Patterns

design patterns for scalable and resilient applications

  • Microservices Architecture

    service decomposition, API gateways, service mesh, domain-driven design

    →
  • Multi-Cluster Architecture

    federation, cluster federation v2, multicluster networking, disaster recovery

    →
  • Hybrid Cloud Architecture

    on-premise + cloud integration, cluster bridging, unified management

    →

Deployment Strategies

strategies for zero-downtime and safe deployments

  • Deployment Strategies

    rolling updates, blue-green, canary, A/B testing, feature flags

    →
  • GitOps with ArgoCD

    declarative deployments, continuous delivery, sync policies, rollbacks

    →
  • Helm Charts

    package management, templating, chart development, repository management

    →

Networking

CNI, service mesh, ingress, network policies

  • Kubernetes Networking

    CNI, Service, Ingress, NetworkPolicy, DNS, service discovery

    →
  • Ingress Controllers

    NGINX, Traefik, HAProxy, AWS ALB, GCE Ingress, Istio Gateway

    →
  • Service Mesh

    Istio, Linkerd, Consul, mTLS, traffic management, observability

    →
  • CNI Comparison

    Calico, Flannel, Weave, Cilium, Antrea, performance comparison

    →

Storage

persistent storage, CSI, backups, data management

  • Kubernetes Storage

    PersistentVolumes, PersistentVolumeClaims, StorageClasses, CSI drivers

    →
  • Stateful Applications

    StatefulSets, headless services, ordered deployment, stable storage

    →
  • Backup & Restore

    Velero, etcd backup, application backup, disaster recovery strategies

    →

Security

secure your Kubernetes clusters

  • Kubernetes Security

    RBAC, security contexts, pod security policies, OPA, secrets management

    →
  • RBAC Best Practices

    roles, clusterroles, bindings, service accounts, least privilege

    →
  • OPA & Gatekeeper

    policy as code, admission control, constraint templates, validation

    →
  • Network Security

    network policies, zero-trust, mTLS, firewall, egress filtering

    →

Monitoring & Observability

metrics, logs, traces, and dashboards

  • Monitoring Stack

    Prometheus, Grafana, AlertManager, node exporters, kube-state-metrics

    →
  • Logging with EFK/ELK

    Elasticsearch, Fluentd, Kibana, log collection, aggregation, analysis

    →
  • Distributed Tracing

    Jaeger, Zipkin, OpenTelemetry, trace collection, performance analysis

    →
  • Alerting Best Practices

    alert rules, receiver configuration, on-call management, runbooks

    →

Operational Best Practices

manage Kubernetes in production

  • Cluster Autoscaling

    cluster autoscaler, HPA, VPA, resource optimization, cost management

    →
  • Resource Management

    resource requests, limits, quotas, limit ranges, burst management

    →
  • Node Maintenance

    draining, cordoning, OS updates, cluster upgrades, node taints/tolerations

    →
  • Cost Optimization

    resource optimization, spot instances, committed use discounts, rightsizing

    →

CI/CD & Automation

automated build, test, and deployment pipelines

  • CI/CD Pipelines

    Jenkins, GitHub Actions, GitLab CI, Argo Workflows, Tekton

    →
  • Argo Rollouts

    progressive delivery, blue-green, canary, analysis, rollback

    →
  • Flux CD

    GitOps, automated sync, image automation, helm integration

    →

Troubleshooting & Debugging

solving common Kubernetes issues

  • Troubleshooting Pods

    CrashLoopBackOff, ImagePullBackOff, OOMKilled, pending pods

    →
  • Troubleshooting Cluster

    control plane issues, etcd problems, networking, node failures

    →
  • Common Kubernetes Issues

    resource exhaustion, DNS issues, certificate expiration, scheduler problems

    →

Interview & Real-World Scenarios

ace your Kubernetes interview

  • Kubernetes Interview Questions

    basic to advanced topics, scenario-based, design questions
