And it was quite the journey. About fifteen years ago, I dabbled a bit in certification via PHP and Zend. Back then, PHP tried to be corporate Java, including the design patterns and certifications that come with it. And I went along! Let’s say it has been a phase, in which I built quite some monstrosities 1. https://www.tibobeijen.nl/2025/02/12/study-tops-for-becoming-a-kubestronaut/ Wed, 12 Feb 2025 05:00:00 +0100 https://www.tibobeijen.nl/2025/02/12/study-tops-for-becoming-a-kubestronaut/ Introduction At KubeCon 2024 in Paris, CNCF introduced the Kubestronaut program. Quoting: The Kubestronaut program recognises community leaders who have consistently invested in their ongoing education and grown their skill level with Kubernetes. Individuals who have successfully passed every CNCF’s Kubernetes certifications – CKA, CKAD, CKS, KCNA, KCSA – will receive the title of “Kubestronaut” From October 2024 through Januari 2025 I completed the five exams. Overal, I think about 2/3 of my preparation time has been spent on CKS alone. https://www.tibobeijen.nl/2023/03/02/kubernetes-community-days-2023-ams/ Thu, 02 Mar 2023 15:00:00 +0100 https://www.tibobeijen.nl/2023/03/02/kubernetes-community-days-2023-ams/ Introduction The last time Kubernetes Community Day took place in the Netherlands was September 2019. Then the pandemic turned the world upside down, and suddenly we find ourselves in February 2023 for the next event. In those three years, the event became bigger, doubling in all aspects: The number of days (2), number of tracks (2), and audience now totaling 450 attendees. So either people fancy in-person events more than ever, or Kubernetes adoption simply continued growing. https://www.tibobeijen.nl/2019/06/13/kubecon-cloudnativecon-2019/ Thu, 13 Jun 2019 10:00:00 +0100 https://www.tibobeijen.nl/2019/06/13/kubecon-cloudnativecon-2019/ The end of May 2019 saw 7700 people, myself included, visit Barcelona to attend ‘KubeCon + CloudNativeCon Europe 2019’. That’s a lot of people and a significant increase of previous editions (Copenhagen 2018: 4300, Berlin 2017: 1500, according to this Dutch source). Next year’s edition will be ‘around the corner’ in Amsterdam and is projected to attract at least 10000 visitors. This is quite telling of the increased adoption of Kubernetes and all associated technologies over the past years.
