Learn Kubernetes the way you'd learn a language: a few minutes a day,
coming back to what you're shaky on, until it sticks.

K8s Dojo is built for engineers who want to genuinely understand
Kubernetes — not memorise answers for an exam and forget them a month later.

WHAT MAKES IT DIFFERENT

Every card explains the reasoning, not just the answer. Why does Kubernetes
behave this way? What breaks in production? What would you actually check
first at 3am? The explanations go into common mistakes, production tips, and
security implications — the things that separate someone who passed an exam
from someone who's debugged a real cluster.

HOW YOU LEARN

• Flashcards — core concepts, direct and to the point
• Scenario cards — realistic situations to reason through, with a walkthrough
of the engineering thought process
• Spot the Bug — find what's wrong in a real manifest
• kubectl Challenges — pick the right command from realistic options

SPACED REPETITION THAT ACTUALLY WORKS

Rate how well you knew each card and the app schedules it accordingly. Cards
you find easy come back rarely. Cards you struggle with come back soon. Your
review queue adapts to you rather than making you grind through everything.

DAILY CHALLENGE

Five cards drawn from across every topic, refreshed each day. A two-minute
habit that keeps everything current.

WHAT'S COVERED

• Workloads & Scheduling — Pods, Deployments, StatefulSets, DaemonSets, Jobs,
affinity, taints and tolerations, resource management, QoS
• Services & Networking — Services, kube-proxy (including nftables mode),
DNS, Ingress, Gateway API, NetworkPolicy, CNI
• Troubleshooting — debugging methodology, Pod error states, node and control
plane issues, RBAC, admission control, live debugging tools

Content spans foundational concepts through genuine production edge cases,
and is grounded in official Kubernetes documentation.

RELEVANT FOR CKA, CKAD AND CKS

The topics align with the domains those certifications cover — but this isn't
a cram tool. It's built to stay useful long after you've passed.

STAY CURRENT

The latest posts from the official Kubernetes blog, right in the app.

WORKS OFFLINE

Content syncs to your device, so you can study on a plane or a bad
connection. Your progress stays on your device.

Built for developers, DevOps engineers, platform engineers, SREs, cloud
engineers and architects.
