Kubernetes Fundamentals Course

Course description:

Kubernetes Fundamentals course is intended for system administrators and application developers who are interested in deploying and orchestrating container applications at scale and have a basic understanding of containers, mainly docker, and want to understand the basic concepts of Kubernetes and it is internal processes.
The online training for beginners starts with a small refresher on what containers are and afterwards it goes and presents the kubernetes architecture and it is main components.
Next, each student will create it is own Kubernetes cluster and also submit workloads under a common cluster across all students simulating a more production like environment. Kubernetes resources like pod, deployment, services, volumes and many more are presented alongside with their major features and each student will have the chance to create and use them in the hands-on laboratories which are at the end of each chapter.

Target audience:

• DevOps engineers
• Linux system administrators
• Systems design engineers
• Architects

Prerequisites for Kubernetes Fundamentals:

• Strong grasp of container basics (recommended training: Docker Fundamentals)

Nice to have:

• Basic familiarity with the Linux command line (commands, arguments, etc.)
• Familiarity with JSON and/or YAML syntax

Information about the Kubernetes certification:

This course is designed to prepare for the exam certification in order to become a certified Associate Deploy & Ops Engineer.
