The Certified Kubernetes Application Developer (CKAD) exam proves that candidates have the skills to design, build, and launch cloud-based applications using Kubernetes. The CKAD was developed by the Linux Foundation and the Cloud Native Computing Foundation (CNCF) to support the growth of the Kubernetes community. The exam is taken online, supervised, and performance-based, meaning candidates complete several tasks using the Kubernetes command line.
