Requirements / Prerequisites
- Intermediate to Advanced Kubernetes Familiarity: This is not an introductory course. Learners are expected to possess a solid working knowledge of Kubernetes concepts, including cluster architecture, core objects (Pods, Deployments, Services, Namespaces), and basic kubectl operations.
- Linux Command-Line Proficiency: Comfort navigating the Linux terminal, executing commands, managing files, and understanding process management is essential, as all exams are conducted in a Linux environment.
- YAML Syntax Knowledge: A strong ability to read, comprehend, and author Kubernetes resource definitions in YAML format is a fundamental prerequisite for practical tasks.
- Containerization Basics: An understanding of container concepts, Docker, or similar container runtimes, and image management is beneficial for grasping application deployment and security aspects.
- Text Editor Acumen: Basic proficiency with a command-line text editor (e.g., Vim, Nano) is crucial for modifying configuration files directly on the exam environment.
- Commitment to Hands-on Practice: Success in these performance-based exams heavily relies on practical application. Learners must be prepared for extensive lab work and self-practice beyond the course material.
