Domain-Based Routing with Kubernetes Ingress

Managing how external traffic reaches your containerized applications is a critical step in production deployment. Understanding how to map domain names to specific services within a cluster ensures your users always reach the correct destination. This text-only course guides you through the core concepts of Kubernetes traffic routing. You will learn how to define, configure, and deploy Ingress resources that inspect host headers and direct requests to the appropriate services, while also exploring modern security and routing best practices. What you'll learn: - Understand foundational Kubernetes networking concepts, including Services, Ingress Controllers, and Ingress resources. - Configure domain-based routing rules to direct traffic from multiple hostnames to different backend services. - Apply TLS certificates to secure your Ingress paths and manage HTTPS traffic. - Verify routing behavior using command-line tools and HTTP host headers. - Explore modern traffic management trends, including an introduction to the Gateway API. - Troubleshoot common routing issues and misconfigured host rules. The course starts with essential networking terminology and foundational architecture before moving into step-by-step configuration files and practical routing scenarios. You will read through detailed explanations, analyze YAML structures, and complete written exercises to reinforce your learning. This course is designed for system administrators, developers, and DevOps beginners who have a basic understanding of Kubernetes pods and services but are new to external traffic routing. No advanced networking experience is required. Start reading today to master domain-based routing in your clusters.
