Kubernetes Fundamentals

This two-day Kubernetes fundamentals training course provides a comprehensive introduction to Kubernetes, covering its architecture, core components, and practical applications. Participants will gain a deep understanding of container orchestration, including deployment, scaling, and management of containerized applications using Kubernetes.

Through hands-on exercises and real-world scenarios, attendees will learn how to set up a Kubernetes cluster, deploy applications, manage resources, and troubleshoot common issues. By the end of the course, participants will be equipped with the knowledge and skills necessary to effectively leverage Kubernetes for containerized application deployment and management in various environments.

You should posses a minimum of two years experience in either IT support functions or Software development and have a foundational knowledge of both.
