Deploy a microservices application to production Kubernetes

Learning Goals

  • Understand Kubernetes architecture and components
  • Deploy and manage applications using Helm
  • Implement proper security with RBAC, Network Policies, and Pod Security Standards
  • Set up monitoring and logging with Prometheus and Grafana
  • Master troubleshooting common Kubernetes issues

Why Kubernetes Matters

Kubernetes has become the de facto standard for container orchestration in modern cloud-native applications. Understanding how to effectively deploy, manage, and troubleshoot Kubernetes clusters is essential for building scalable, resilient systems.

Current Knowledge

I have basic experience with:

  • Running Docker containers locally
  • Basic kubectl commands
  • Simple deployments with YAML manifests
  • Understanding of pods, services, and deployments

Learning Objectives

Cluster Management

  1. Architecture: Master control plane components (API server, etcd, scheduler, controller manager)
  2. Node Management: Understand kubelet, container runtime, and node operations
  3. Networking: Deep dive into CNI plugins, services, ingress, and network policies

Application Deployment

  1. Manifests: Advanced YAML manifest patterns and best practices
  2. Helm: Create and use Helm charts for application packaging
  3. Operators: Build Kubernetes operators for complex applications

Security & Operations

  1. RBAC: Implement role-based access control
  2. Secrets Management: Secure handling of sensitive data
  3. Pod Security: Implement Pod Security Standards
  4. Network Policies: Secure network traffic between pods

Observability

  1. Monitoring: Set up Prometheus and Grafana for cluster monitoring
  2. Logging: Implement centralized logging with Fluentd and Elasticsearch
  3. Tracing: Distributed tracing with Jaeger or OpenTelemetry

Practical Projects

  1. Local Cluster: Set up a multi-node Kubernetes cluster using kind or k3d
  2. Microservices App: Deploy a 3-tier application with proper networking and security
  3. GitOps Pipeline: Implement GitOps with ArgoCD or Flux
  4. Production Setup: Configure a production-ready cluster with monitoring, logging, and backup

Certification Goals

  • Certified Kubernetes Application Developer (CKAD)
  • Certified Kubernetes Administrator (CKA)

Expected Timeline

This learning path is estimated at 200 hours over 6 months, focusing on:

  • 2 hours/week: Foundational concepts
  • 4 hours/week: Hands-on labs and projects
  • 8 hours/month: Building a portfolio project
