Linkerd Essentials Online Course
Linkerd Essentials Online Course
This course is designed to provide a step-by-step guide to mastering Linkerd, a lightweight, high-performance service mesh for Kubernetes. Linkerd enhances security, reliability, and observability in microservices by managing service-to-service communication automatically. Unlike other service meshes, Linkerd is simple to use, fast, and built specifically for Kubernetes environments.
In this course, you will learn how to install and configure the Linkerd CLI manually, inject Linkerd into applications, and deploy progressive delivery strategies using Flagger. By the end of this course, you will have a solid understanding of service mesh concepts and be able to integrate Linkerd into Kubernetes environments effectively.
