CK-X is a self-hosted mock exam simulator for the CKAD, CKA, and CKS Kubernetes certifications, providing timed exam sessions with hands-on labs running on pre-configured local clusters. It deploys via Docker (using k3d and Docker-in-Docker) and includes a web-based exam interface with real-time solution verification.
Use cases
- practice for the CKA exam with timed hands-on labs
- prepare for CKAD certification with realistic mock exams
- simulate the CKS exam environment locally
- get hands-on Kubernetes practice clusters without cloud costs
- verify my kubectl answers automatically during practice
- run Kubernetes certification practice exams offline
When to choose
- you want a free, self-hosted, exam-like environment with real clusters for CKAD/CKA/CKS prep
- you need timed practice sessions with automatic solution verification on your own machine
- you want to avoid queues or cloud-based lab limits of commercial exam platforms
When to avoid
- you need a license permitting commercial or production use (BSL 1.1 restricts it)
- you want official exam questions or a pass guarantee - it is independent of CNCF/Linux Foundation
- you need certifications other than CKAD/CKA/CKS or a fully managed hosted service
