What is a Kubestronaut?

The “Kubestronaut” title is a badge of honor that CNCF has been offering since March 2024 to Kubernetes professionals who have successfully passed all the Kubernetes certifications(CKA, CKAD, CKS, KCNA, KCSA). This term is meant to be used within the Kubernetes community to denote someone who has mastered the full spectrum of Kubernetes knowledge, from foundational concepts to application development to security. Apart from the catchy title itself, this programme brings 5 50% off discounts for other CNCF certifications, a “Kubestronaut” branded jacket, 20% off three CNCF events and a mention of you together with the other kubestronauts on the CNCF website.
