I received the Kubestronaut title, and I wrote up how it went on Medium.

It started with a real project: migrating a telecom private cellular network from Docker Compose to Helm on Kubernetes without a complete Kubernetes background. The cluster did not behave as expected and I did not know which resources to create or how to structure a Helm chart. I turned that into a learning mission, and the certifications gave me a clear mental map of Kubernetes.

A few of the 20 recommendations from the article:

• Do not follow anyone’s study method blindly. Each person learns differently.
• Master the Linux command line. It saves time in the exam.
• Use the Kubernetes documentation and CLI help. Many questions are inspired by them.
• Build your own labs and use mock exams, and work on real projects alongside the study.
• Failing once or twice is fine. Reflect, study and retake it.
• Teach what you have learned, because it reinforces your knowledge.
