Day 50: MASTER Kubernetes Ingress | PART 2 | Path-Based Routing on Amazon EKS with AWS ALB | CKA 2025 👉 GitHub Repository: https://github.com/CloudWithVarJosh/CKA-Certification-Course-2025 👉 CKA 2025 Playlist: https://youtube.com/playlist?list=PLmPit9IIdzwRjqD-l_sZBDdPlcSfKqpAt&si=1JNRkoNa75AOJx0o 📚 Welcome to Day 50! In this second part of our 3-part Ingress series, we move from theory to hands-on practice — deploying a real-world, path-based routing solution on Amazon EKS using the AWS Load Balancer Controller (ALB Ingress Controller). This demo mirrors production-grade architecture, where routing is based on /iphone, /android, and / paths — much like what real users would hit via your app or website. We also explore how pod distribution across AZs is achieved using topologySpreadConstraints, and dig deep into target-type: ip vs. instance. 🛠 What You’ll Learn: ✅ Installing AWS Load Balancer Controller in EKS ✅ Deploying multiple services (Android, iPhone, Desktop) ✅ Understanding and configuring topologySpreadConstraints ✅ Creating a path-based Ingress resource with real-world routing ✅ IngressClass demystified ✅ Verifying behavior through CLI and AWS Console ✅ Pros & cons of target-type: ip vs instance ✅ Final end-to-end validation via ALB DNS 💡 By the end of this lecture: You'll be able to confidently configure and troubleshoot path-based routing using AWS ALB in an Amazon EKS environment — with production-readiness in mind. 🔗 Stay Connected: 👉 LinkedIn: https://linkedin.com/in/varun-joshi-2b516752 👉 GitHub: https://github.com/CloudWithVarJosh 💬 Got questions?
