Certified Kubernetes Administrator (CKA) Readiness: Administer Clusters Under Real Exam Conditions
Signature Course No. 348 — A Signature AI Socratic Coaching Course.
No experience needed — your coach starts where you are.
A New Kind of Learning
Socratic coaching, delivered by an agentic AI coach.
Not a course you watch. An AI coach you work with.
The Lighthouse Coach begins by discovering how you think about the subject, teaches what is missing, and gives you realistic practice before asking you to prove that you can use it. You may test out of concepts you already understand, while capstones turn the learning into a practical plan, decision, conversation, or other real-world result.
The curriculum is deliberately authored; the AI delivers it through coaching. It is not an AI randomly generating lessons.
A coach that teaches by asking — not by lecturing
The Lighthouse Coach is an AI Socratic coach built on Cognosco Learning's Certified Kubernetes Administrator (CKA) Readiness: Administer Clusters Under Real Exam Conditions course, in the Personal Effectiveness & Well-Being category. It does not play videos at you. It holds a conversation: it asks you a question, listens to your answer, names the misconception it hears, affirms what you got right, and asks the next question — the way a great coach works in the room.
Desired state is the system's religion. You rarely command a pod to exist; you declare an object, store it, and let controllers pursue it — and status is evidence, not decoration. This course teaches administration as performance: every task performed at a terminal, and every result proven from the cluster's own output rather than asserted from hope.
It starts with the system. The control plane decides and the worker nodes do: the apiserver as the only door, etcd as the cluster's memory, the scheduler binding pods and nothing more, and the control loops endlessly comparing desired state with observed state. You will learn to name the stage of that loop any failure lives in — and to read status before you act and after you act.
It works in two movements. First, Module 1 — Build and Configure the Cluster — work through Concepts 1–9, finishing with From Bare Nodes to Serving Workloads; then, Module 2 — Operate, Store, and Rescue the Cluster — work through Concepts 10–18, finishing with Rescue the Degraded Cluster.
Both capstones produce real artifacts — a Cluster Bring-Up and Handover Record for a cluster taken from bare nodes to serving workloads, written so a stranger could operate from it; and an Incident Recovery and Verification Report for a degraded production cluster rescued under time pressure, each fault recorded with its convicting evidence and its repair.
The honesty standard is part of the course. This is a readiness course, not a promise: it does not promise that you will pass the Certified Kubernetes Administrator examination, does not promise a score, and does not claim to reproduce examination tasks. What it offers is harder and more useful — the administration itself, the terminal discipline, the verification habit, and the timed routine, practiced on fresh scenarios until the work holds up without help.
The course is self-paced and always on — roughly 30 minutes per concept, about 9 hours in full, taken in as many sittings as you like. You can type your answers, or talk out loud: the Voice Coach speaks its questions and listens to your spoken replies. Learners who already know the material can test out concept by concept.
Certified Kubernetes Administrator (CKA) Readiness: Administer Clusters Under Real Exam Conditions is part of The Lighthouse Signature Series — the online counterpart to the one-day, in-person learning Cognosco Learning has delivered since 2002.

Every learner moves through the same discipline a Cognosco instructor would insist on in the room.
Diagnose
The Coach starts where the course starts: with the cluster as a system. Say which components you have actually seen evidence of, and which you have only assumed were working because nothing complained; explain in your own words why a deleted pod returns with a different name, and which component did it; and say what the cluster would believe tomorrow if etcd were restored from a day-old backup tonight. Every concept opens with three questions that locate where you actually stand, and your answers shape how deeply the Coach works the concept with you. Everyone begins with Module 1 — no skipping the foundations you only think you have.
Learn & Practice
Work each concept in conversation with the Coach — spoken or written — then practice it against realistic situations until it holds up.
Prove
Every concept ends in proof: answer the check cold and demonstrate the skill. Know it already? Test out and take credit immediately.
Capstone
Finish with two capstones — From Bare Nodes to Serving Workloads for Module 1 and Rescue the Degraded Cluster for Module 2 — that pull the whole course together, and earn the certificate.
What You'll Learn
Declare, verify, prove — in that order, every time. Every skill in this course is the same discipline wearing a different subsystem's clothes: declare the state you intend, let the controllers pursue it, and read the cluster's own status back as the only acceptable proof that you got it.
Module 1 builds and configures the cluster. The Cluster as a System; Install and Bring Up a Cluster; Configure Access and RBAC; Nodes, Labels, Taints, and Availability; Workloads in Production Shape; Scheduling Decisions; Configuration and Secrets Safely; Services That Reach Workloads; and Ingress and Network Policy — the foundation, in the order an administrator actually needs it.
Module 2 operates, stores, and rescues it. Persistent Storage; Logging, Monitoring, and Resource Health; Upgrades Without Breaking the Cluster; Backup, Restore, and etcd Care; Security and Admission Basics for Administrators; the three troubleshooting disciplines — workloads, services and networking, and cluster components; and The Administrator's Exam Routine, timed, verified, and finished.
And it holds its boundary throughout. What containers and Kubernetes are — the literacy course — is taught in its own neighboring course, Signature Course No. 246, and is assumed here. This course is the helm watch, not the chart: not can you explain it, but can you do it, correctly, while time is running, and prove the cluster is in the state you claim.
What you will learn
- Install and verify a Kubernetes cluster and explain what every component you brought up does
- Configure access, contexts, and role-based permissions to least privilege
- Maintain nodes, shape workloads, and control scheduling decisions deliberately
- Connect workloads with services, ingress, and network policy that you can prove work
- Provide persistent storage that binds, persists, and is reclaimed on stated terms
- Monitor, log, upgrade, back up, and secure a cluster as routine administration
- Diagnose and fix broken workloads, broken networking, and broken cluster components by sequence
- Perform the whole repertoire under timed, examination-style conditions with verification at every step

Built for administrators who carry a cluster
Platform and systems administrators — who run Kubernetes clusters now, or are about to, and need the full administration repertoire performed to a verifiable standard, not described; and site reliability and operations engineers whose pager goes off for node, networking, and control-plane failures, and who need a diagnosis sequence that holds up at 3 a.m.
Engineers preparing for the CKA examination — who have the literacy, have touched clusters, and now need deliberate, timed, terminal-shaped practice mapped to the examination domains.
Technical leads who still carry a cluster — who review administrators' work and need to know what a correct drain, a safe upgrade, and a proven fix actually look like. This course assumes you are comfortable at a Linux command line and can edit a YAML manifest without distress; it does not assume you have ever installed a cluster, drained a node, or restored etcd.

Before you enroll
What is a Socratic coaching session?
A conversation, not a video. Your coach asks a question; you answer — out loud by voice, or by typing — and the coach responds to what you said: naming the misconception it hears, affirming what you got right, and asking the next question. You advance only when you have mastered each concept, so a finished course means the learning held.
How long does it take — and how long do I have?
About 30 minutes per concept. Learn in sittings of any length; your progress is saved as you go. You have a full year from purchase to finish, and you can revisit and retake within that year.
What does the certificate verify?
That you completed every concept and both capstones of this course. Anyone can confirm a Cognosco certificate online — enter its certificate ID on our verification page.
What if it isn't for me — what are the refunds?
If you have not started, cancel for a full refund within seven days of purchase. Once you have started, there is no cash refund — stop before finishing and we credit the full amount you paid toward any other course in the library (credit valid one year from your original purchase). Once you complete the course, no refund or credit applies.
