Essential Fundamentals for Self-Paced CKA (Kubernetes) Certification. Module 1: Introduction.

Image
  Introduction: The Certified Kubernetes Administrator (CKA) certification is one of the most valued in the world of container management. Before diving into the CKA preparation course, it's important to understand certain key concepts and components of Kubernetes. This article covers the basics that every aspirant should know to build a solid foundation before starting their training. 1. What is Kubernetes? Kubernetes is an open-source platform designed to automate the deployment, scaling, and operation of containerized applications. It simplifies the management of distributed applications, ensuring they run efficiently and reliably across different environments. The main goal of Kubernetes is to manage containers, which are software units that include the code and its dependencies, providing an isolated environment for running applications. 2. Kubernetes Architecture Kubernetes follows a cluster architecture with two main types of nodes: Master and Worker. These nodes work togeth...
