Learn Kubernetes

Learn Kubernetes through prerequisites, core workflows, projects, troubleshooting, and production practices.

Best for

  • Running and coordinating containerized services across multiple nodes
  • Applications that need declarative rollout, scaling, service discovery, and recovery
  • Teams operating container platforms beyond a single host

Prerequisites

  • Docker/container fundamentals
  • YAML and command-line basics
  • HTTP, networking, DNS, ports, and application health concepts

Learning sequence

Recommended Learning Order

  1. 1

    Stage 1

    Cluster model, Pods, Deployments, ReplicaSets, and kubectl

  2. 2

    Stage 2

    Services, DNS, configuration, Secrets, and namespaces

  3. 3

    Stage 3

    Storage, probes, resource requests/limits, and autoscaling

  4. 4

    Stage 4

    Rollouts, Jobs, CronJobs, ingress, and policy basics

  5. 5

    Stage 5

    Troubleshooting with get/describe/logs/events, security, and observability

Study Timeline

3 hours/week

Use a local cluster and inspect every object you create.

6 hours/week

Deploy a multi-component app and practice rollouts, services, config, and debugging.

10 hours/week

Operate a realistic namespace with storage, probes, policies, monitoring, and failure drills.

Project Progression

Beginner: Deployment + Service for a containerized app

Intermediate: app with ConfigMap/Secret, probes, resources, and rolling update

Portfolio: multi-service deployment with ingress, persistent storage, observability, policy, and rollback drill

Common Mistakes

  • Debugging YAML only instead of inspecting live object status and events
  • Using liveness probes for dependencies that should not restart the process
  • Omitting resource requests and limits
  • Treating Secrets as encryption by default
  • Changing a Deployment without knowing how to inspect and undo a rollout

Job-Ready Skills

  • Workloads and controllers
  • Services/networking
  • Configuration and Secrets
  • Storage
  • Probes/resources
  • Rollouts and troubleshooting

Frequently Asked Questions

Should I learn Docker before Kubernetes?

Yes. Understand images, containers, ports, environment variables, volumes, logs, and container lifecycle before learning Kubernetes orchestration.
