Description

A Kubernetes Operator is a custom resource and custom controller that extends the functionality of Kubernetes by automating the management of complex stateful applications.Kubernetes Operator is a powerful tool for managing complex stateful applications on Kubernetes. It allows you to automate common tasks, such as scaling, upgrading, and backing up your applications, by defining custom resources and controllers that extend the Kubernetes API.In today's fast-paced world, being able to effectively manage containerized applications is crucial for businesses to succeed. That's why learning how to build Kubernetes Operators is a valuable skill.This course is designed to teach you how to build Kubernetes Operators using popular tools like Kubebuilder and Operator-SDK. You'll start with the basics of Docker and Kubernetes, learning key concepts like Pods, ReplicaSets, and Deployments, as well as the Kubernetes architecture and API groups for building and managing containerized applications.Next, you'll develop programming skills in the Go language, including arrays, slices, functions, structures, pointers, JSON marshaling, and method development etc.. With these foundational skills in place, you'll dive into building custom Kubernetes Operators, starting with setting up the required tools and scaffolding the project, and progressing to creating custom resource types, writing code for the controller, setting up the manager, and deploying the operator.Throughout the course, you'll gain experience applying Kubernetes Operators to real-world business scenarios. By the end of the course, you'll have a deep understanding of Kubernetes Operators and the skills needed to create and manage them effectively in any environment.
