New The CKA course: 17 modules, 134 labs, 15 mock exams
Hands-on prep for cloud and DevOps certifications: live clusters, labs graded against what you built, and timed mock exams.
First full track: the CKA, with 305 CKA tasks across all 5 exam domains. CKAD and CKS are in progress beside it.
How it works
The same loop as a hands-on exam: a task, a live environment and a terminal. You learn by fixing real things, not by recognising answers.
Short lessons and step-by-step demos for every competency, with links to the official docs.
A lab puts a real environment into a broken state. You get a task and a terminal.
Checks read the live state and show what passed, so you know exactly what is left.
Mock exams weighted like the real one, with a score per domain to show where to focus.
Courses
Each card uses the real module, lesson, quiz and lab counts from that track. The CKA is the one with free starter labs.
Course and labs · Free starter labs
Install, run, secure and troubleshoot kubeadm clusters: lessons, demos, hands-on labs and timed mock exams.
CKAD · In progress
Design, build and deploy applications on Kubernetes. The course, labs and mock exams are in progress and still growing.
CKS · In progress
A starter set for cluster hardening, supply chain and runtime security. Not the full exam. Requires a passed CKA.
KCNA · In progress
A reading course and original practice questions on cloud-native fundamentals. No hands-on labs.
KCSA · In progress
A reading course and original practice questions on Kubernetes security. No hands-on labs.
Cloud Practitioner · In progress
Cloud concepts, security, technology and billing, as a course and original practice questions.
Solutions Architect · In progress
Resilient, secure and cost-aware architectures, as a course and original practice questions.
In every track
Real machines and clusters with root access, so you can stop a service, edit a manifest or restore a backup.
Checks read the live state. You see every check as passed or failed, so you know what is left to fix.
Many labs come in variants, so a second attempt tests your skill, not your memory of the first one.
Weighted by domain like the real exam, with one score at the end and a breakdown per domain.
Every lab runs in its own microVMs with its own kernel and network, so nobody else's mistakes reach yours. How labs are isolated.
Written from the public curricula and official docs. We never use or reconstruct real exam questions.

Mock exams
10 full mock exams of 17 to 19 tasks each, and 5 domain mocks of 16 tasks that drill one domain at a time. Every mock is timed at 120 minutes and scored per domain. Pass mark: 66%.

FAQ
Hands-on practice for cloud and DevOps certifications, starting with the CKA. Each lab gives you a live environment (for the CKA, a real kubeadm cluster with a control plane and a worker node), puts it into a specific state, often a broken one, and gives you a task. You solve it in a terminal, and an automatic check grades the live environment and shows which parts passed.
CKA, CKAD and CKS have courses and hands-on labs on real kubeadm clusters, with timed mock exams. KCNA, KCSA, Cloud Practitioner and Solutions Architect – Associate have courses and original practice questions. The lab runtime is kubeadm clusters only, so the AWS pages do not include an AWS account. Every other certification is listed on the Labs pages and gets the same kind of course page when its track is in the catalog.
No. Every task is original and written from the public curriculum and the official Kubernetes documentation. Candidates agree not to share exam content, and we never use or reconstruct it.
Each lab has a set of checks that read the state of the live cluster: is the node Ready, does the Service have endpoints, does the Role allow exactly what was asked. You see every check as passed or failed, so you know what is left to fix. There is no answer text to match.
The starter CKA labs are free, with no card needed. We plan paid plans too: a monthly or yearly subscription, a one-time pass for a single certification, and a Teams plan. They are not on sale yet; their prices go on our pricing page before they are, and we take no payments or pre-orders until then.
