Frequently Asked Questions
How does it work?
A Kubernetes cluster simulator runs entirely in your browser. You practice kubectl commands and manage resources in real time, no real cluster or cloud. Because everything is local, loading is instant and there’s no network latency or server wait.
Does it resemble a real cluster?
Yes. We test against the OpenAPI spec and build our courses from the official Kubernetes docs, so behavior matches real clusters as closely as possible. But Kubernetes is a complex system so some commands may behave differently, especially those that are not in the course yet.
Do I need prior experience with Kubernetes?
No. The courses start from scratch. Basic Linux command-line familiarity is helpful but not required. We cover the essentials as you go.
Does it prepare me for the CKA or CKAD exam?
That's the goal. The simulator reproduces the terminal-only exam environment and the courses are built from the official Kubernetes documentation. The common foundation is complete. Full CKA and CKAD preparation is a work in progress: new lessons are added every day. We are not affiliated with the Linux Foundation, and the exam voucher is not included.
What kind of support do you offer?
Support is by email only. There is no 24/7 hotline. As a solo-built project, response time may vary. I do my best to reply to everyone within a reasonable delay.
Is the code open source?
Not yet. The platform is currently closed source. Opening the lesson content is something I am considering. For the cluster simulator itself, no decision has been made.
Is the content AI-generated?
Yes, partially. AI is used to help write course content and code. Everything is reviewed, verified, and corrected before being published.
