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 track: the CKA, with 305 CKA tasks across all 5 exam domains. Kubernetes, AWS, HashiCorp and Linux follow, one track at a time.
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
The CKA course is ready to start. The next tracks follow in order, each with labs on real infrastructure and timed mocks.
Course and labs · Free starter labs
Install, run, secure and troubleshoot kubeadm clusters: lessons, demos, hands-on labs and timed mock exams.
CKAD · Coming next
Design, build and deploy applications on Kubernetes, on the same real-cluster lab engine.
CKS · Planned
Harden clusters, secure the supply chain and detect threats at runtime. Requires a passed CKA.
KCNA · Planned
The cloud-native fundamentals, with timed practice quizzes and labs to see each concept for real.
KCSA · Planned
Security fundamentals for Kubernetes and the cloud-native stack, with explained 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.

Learning paths
Each path lines up the certifications for one job, in the order to take them. New to all this? Start here.
Path
Run production clusters: install and upgrade with kubeadm, manage access, storage and networking, and fix what breaks.
1 course · 38.5 h · 134 labs
Path
Ship applications to Kubernetes: multi-container Pods, probes, Jobs, Helm and deployment strategies.
Coming next
Path
Start with the administrator path, then lock clusters down: hardening, supply chain and runtime security.
Planned
Path
Build on AWS and manage it as code: the AWS associate exams and Terraform, on real cloud environments.
Planned
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.
The CKA first: every competency in the public curriculum already has at least one lab, and there are timed full and domain mock exams. The CKAD is next, then the CKS. After that we plan the other Kubernetes and cloud-native certifications and the AWS, HashiCorp (Terraform and Vault) and Linux ones, one track at a time. The Labs pages list every certification and where each one stands. Multiple-choice exams get timed practice quizzes as well as labs.
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.

A free account includes 5 starter CKA labs, one in each exam domain, on real kubeadm clusters with the same automatic grading as every other lab. No card needed.
