Kubernetes Zero to Hero: Step-by-step Guide

Kubernetes Zero to Hero: Step-by-step Guide

A comprehensive roadmap to master Kubernetes concepts, tools, and best practices—from fundamentals to advanced topics.

1. Kubernetes Basics

  • k8s History: Learn the evolution and origins of Kubernetes.

    • Action: Read Kubernetes documentation, and explore articles on its development.

  • Monolithic vs Microservices: Understand architectural paradigms.

    • Action: Compare monolithic and microservices models, focusing on pros/cons.

2. Kubernetes Architecture

  • Kubernetes Architecture: Study the overall design—nodes, master components, etc.

    • Action: Review official Kubernetes diagrams and docs.

3. Getting Hands-On

  • Kubectl: Master the command-line tool for Kubernetes clusters.

    • Action: Practice basic kubectl commands (get, create, delete, apply).

  • Create Kubernetes Architecture by Yourself

    • KIND Setup on Local

      • Action: Install KIND, create a local test cluster.

    • KIND Cluster Creation

      • Action: Follow the KIND documentation to spin up clusters.

    • Kubeadm Setup & Installation

      • Action: Try bootstrapping a Kubernetes cluster using kubeadm.

4. Core Concepts

  • Cluster Creation

    • Action: Create clusters using kind, kubeadm, or a cloud provider.

  • Namespaces: Logical separation within a cluster.

    • Action: Create and manage namespaces.

  • Pods: Smallest deployable unit.

    • Action: Write and deploy basic pod manifests.

  • Deployments: Manage stateless applications.

    • Action: Create deployment manifests, scale and update deployments.

  • ReplicaSet vs StatefulSet vs Deployment: Understand resource types.

    • Action: Research differences, try deploying each.

5. Advanced Workloads

  • Labels & Selectors: Organize and select Kubernetes objects.

    • Action: Experiment with labels/selectors in manifests.

  • Rolling Update in Deployment: Zero-downtime application updates.

    • Action: Trigger rolling updates, observe changes.

  • ReplicaSets

    • Action: Explore scaling and self-healing behavior.

  • DaemonSets: Run a copy of a pod on all (or some) nodes.

    • Action: Deploy daemonized workloads.

  • Jobs & CronJobs: Batch and scheduled tasks.

    • Action: Create and execute jobs, schedule with cronjobs.

6. Storage

  • Persistent Volume (PV)

    • Action: Define persistent storage in the cluster.

  • StorageClasses

    • Action: Understand dynamic provisioning.

  • Persistent Volume Claim (PVC)

    • Action: Request PVs from StorageClasses.

7. Networking and Services

  • Services: Expose deployments internally/externally.

    • Action: Define ClusterIP, NodePort, and LoadBalancer services.

  • Ingress: HTTP/S routing into a cluster.

    • Action: Deploy and configure an Ingress resource.

8. Configurations

  • Annotations, ConfigMaps, Secrets

    • Action: Attach metadata; use ConfigMaps for config data; Secrets for sensitive data.

9. Resource Management

  • Resource Quotas & Limits

    • Action: Practice setting limits/requests for CPU & memory.

  • Probes (Liveness, Readiness)

    • Action: Add health checks to pods.

  • Taints/Tolerations, Node Affinity

    • Action: Schedule workload placement and constraints.

10. Security & Access Control

  • Role-Based Access Control (RBAC)

    • Action: Create user roles and permissions.

  • Resource Quotas

    • Action: Limit resource usage per namespace.

11. Monitoring and Logging

  • Kubernetes Dashboard: Visual cluster monitoring.

    • Action: Deploy the dashboard, explore cluster health and utilization.

12. Extend Kubernetes

  • Custom Resource Definitions (CRDs) & Operators

    • Action: Extend Kubernetes with custom objects/logic.

  • Helm: Kubernetes package manager.

    • Action: Install Helm, deploy an application chart.

13. Advanced Patterns

  • SideCar / Init Containers

    • Action: Use sidecars/init containers in project manifests.

  • Istio Service Mesh: Advanced networking, security, and observability.

    • Action: Install Istio and test features.

14. Real-World Project

  • Small Project: For example, try a Django notes app.

    • Action: Containerize, deploy with Kubernetes, and expose using Ingress.

Tips

  • Learn incrementally—don’t try mastering everything at once.

  • Practice hands-on with real clusters.

  • Join communities and follow open-source discussions for updates.
