CKAD — Certified Kubernetes Application Developer — is the CNCF/Linux Foundation credential for building and deploying cloud-native applications on Kubernetes, tested through a hands-on, performance-based exam rather than multiple choice.
What it verifies
CKAD confirms someone can design, build, and deploy applications for Kubernetes — application design, configuration, multi-container pod design, observability, and services and networking from the developer's side of the cluster, distinct from cluster administration itself.
Where it fits on the roster
CKAD isn't currently a named requirement on a published calibre° role — Platform Engineer checks CKA and CKS for cluster administration and security specifically. CKAD is listed in calibre°'s certification catalog for engineers whose application-layer Kubernetes work is being verified as part of a specified role. Full catalog: Verification.
How calibre° verifies it
Status is checked against the Linux Foundation's certification verification before roster eligibility, the same primary-source standard applied to every certification calibre° lists. Full procedure: Verification.
FAQ
How is CKAD different from CKA?
CKAD tests application development and deployment on Kubernetes. CKA tests cluster administration — install, configure, troubleshoot the cluster itself. They verify different work.
Is CKAD a hands-on exam?
Yes — it's performance-based, run against a live Kubernetes cluster, not a written knowledge test.
Does CKAD expire?
Yes — CNCF certifications are valid for 2 years and require recertification.
