The Complete Kubernetes Guide

From fundamentals to production-grade deployments. Master container orchestration with our comprehensive guide covering security, cost optimization, and managed services.

What is Kubernetes?

Kubernetes (K8s) is an open-source container orchestration platform that automates deploying, scaling, and managing containerized applications. Originally developed by Google, it's now maintained by the Cloud Native Computing Foundation (CNCF) and has become the de facto standard for container orchestration.

This comprehensive guide covers everything you need to know about Kubernetes—from basic concepts to production-grade deployments, security hardening, cost optimization, and choosing between managed services like AWS EKS, Azure AKS, and Google GKE.

Frequently Asked Questions

Common questions about Kubernetes

What is the difference between Docker and Kubernetes?
Docker is a containerization platform that packages applications into containers. Kubernetes is an orchestration platform that manages, scales, and deploys those containers across multiple servers. Think of Docker as creating the containers and Kubernetes as managing them at scale.
Should I use EKS, AKS, or GKE?
Choose based on your cloud provider: EKS for AWS-heavy environments, AKS for Microsoft/Azure ecosystems, and GKE for the most mature Kubernetes experience with features like Autopilot. GKE is often considered the most feature-rich, while EKS offers the deepest AWS integration.
How do I secure my Kubernetes cluster?
Key security practices include: enabling RBAC, using network policies, encrypting secrets at rest, scanning container images, implementing Pod Security Standards, and regularly updating Kubernetes versions. Start with our Kubernetes security articles.
How much does Kubernetes cost?
Kubernetes itself is free and open-source. Costs come from: cloud provider fees (EKS charges ~$0.10/hour per cluster), compute resources (nodes), and operational overhead. Managed services reduce ops costs but add platform fees. See our cost optimization guide to reduce spend by 30-50%.
