Ingress, TLS & Auto-Scaling Lab
Transform TaskFlow into an externally accessible application via Ingress, HTTPS/TLS security, and automatic scaling. Install Nginx Ingress Controller, configure path-based routing, generate TLS certificates with cert-manager, and implement HPA for dynamic scaling under load.
Lab Overview
🛠 Lab from the Platform Engineering Bootcamp. Used in Week 9. Bootcamp landing page: https://academy.tekanaid.com/bootcamps/platform-engineering-bootcamp Parent course(s):
- Week 9: Kubernetes Intermediate: Production Deployments (slug: kubernetes-intermediate)
🟡 Beta bootcamp lab. Hands-on instructions, check scripts, and solve scripts are in place. Lab is part of the running TaskFlow project that grows across all 21 weeks of the bootcamp.
⚠️ Note: The ingress-nginx project is retired/EOL as of March 2026 (no further releases or security patches), and the upstream README now steers new users toward the Gateway API. It is used here only for the exercise because it is still widely deployed; for new production work, prefer the Gateway API or a maintained controller (Traefik, Envoy Gateway, F5 NGINX Ingress, or a cloud load-balancer controller).
Expose TaskFlow to the internet using Nginx Ingress Controller 1.12+, secure with TLS certificates, and implement horizontal pod autoscaling. Master production exposure patterns, certificate management, and automatic scaling based on metrics.
What You'll Learn

Create Ingress resources with path-based routing for TaskFlow frontend and backend
Secure TaskFlow with TLS certificates using cert-manager
Install Metrics Server and configure Horizontal Pod Autoscaler for dynamic scaling
Test autoscaling behavior under load and monitor scaling events
