K8s Guide is the complete way to learn Kubernetes - from your very first pod to Kubestronaut - and to pass all five Cloud Native certifications: CKA, CKAD, CKS, KCNA, and KCSA. Most Kubernetes apps are a static pile of flashcards. K8s Guide is built to make you actually understand Kubernetes, then prove it. LEARN IT - THE GUIDE A from-scratch path through Kubernetes, written for a phone screen instead of squeezed in from a website. 50 in-depth lessons across eight areas - Containers, Foundations, Workloads, Networking, Configuration, Security, Operations, and Ecosystem Tools - that build real understanding, absolute beginner to expert. • Starts before Kubernetes even begins: what a container is, how it differs from a VM, and why orchestration exists • Native diagrams drawn for mobile - traffic flows, control loops, and cluster architecture you can actually read on a phone, not pinch-to-zoom web images • Dense topics broken into clean tables, key-point lists, and step-by-step sequences instead of walls of text • Ecosystem Tools coverage beyond core Kubernetes - Argo CD, Istio, Prometheus, Cilium, Helm, Kustomize, cert-manager, OPA Gatekeeper, Kyverno, Falco, Trivy, and KEDA • Every concept explained in plain language, so it sticks PROVE IT - CERTIFICATION PREP All five CNCF certifications, fully built out, with 600+ practice questions and 160+ certification lessons across 30 exam domains. • Every quiz mixes multiple-choice with hands-on build tasks - fill in real YAML, assemble a kubectl command, order the steps, spot the bug - shuffled in like the real exam, not a separate mode • An adaptive quiz engine weights questions toward whatever you're getting wrong, so weak areas resurface instead of drilling what you already know • Study mode for instant feedback and explanations, or Test mode for a full exam simulation with results at the end • A mastery score per certification blends quiz accuracy with lesson coverage into a single readiness number - so you always know what to study next, and when you're actually ready EVERYTHING INCLUDED • The full Guide plus all five certification tracks - CKA, CKAD, CKS, KCNA, KCSA • Hands-on build questions mixed into every quiz, alongside multiple choice • Look Up - a fast reference search to find any concept, command, or term in seconds • Native, mobile-first diagrams throughout • Adaptive quizzing with per-certification readiness and weak-domain call-outs • A built-in Blog with the latest Kubernetes articles and release notes • Bookmark any lesson or question for later, synced across your devices • Home Screen widgets for your streak, active certification, and a rotating Kubernetes tidbit • Optional local study reminders on your own schedule • Kubestronaut badge tracking via your public Credly profile (entirely optional) • iCloud sync for progress, quiz history, and bookmarks - in your own private iCloud, not a server we run BUILT DIFFERENTLY, ON PURPOSE No account. No login. No data collection of any kind - your study data lives in your own iCloud and nowhere else. No ads, no paywalls, no subscriptions; every lesson and question is free. (There's an optional tip jar if you'd like to support development - but nothing is ever locked.) Kubernetes itself is open source, built on the idea that knowledge should be open to everyone. This app is built on the same idea. Whether you're chasing your first certification or going for the full Kubestronaut set, K8s Guide is built to get you there.
