Automate HTTPS on Gateway API with Cert-Manager Automating HTTPS in Kubernetes is no longer optional; it’s mandatory for production. In this video, I show you how to automate TLS certificates for Gateway API + NGINX Gateway Fabric using Cert-Manager, step by step, with a real demo. In the previous video, we manually generated a TLS certificate using OpenSSL. That works for demos but completely fails in real production because manual certificate rotation, renewal, and secret management become unmanageable. So today, you’ll learn how to automate the entire workflow using Cert-Manager, the industry-standard tool for managing certificates in Kubernetes. What You’ll Learn ✔ Why Cert-Manager is required for real-world Kubernetes clusters ✔ How Cert-Manager automatically creates, renews & rotates certificates ✔ Installing Cert-Manager (controller, webhook, CA injector, CRDs) ✔ Creating a ClusterIssuer to act as a Certificate Authority ✔ Generating a TLS certificate automatically using the Certificate CRD ✔ How Cert-Manager stores keys inside Kubernetes Secrets ✔ Connecting the generated TLS secret to a Gateway API listener ✔ Testing HTTPS end-to-end using a real application ✔ Production-ready workflow for microservices & gateway automation ▬▬▬▬▬▬▬ Timestamps ⏰ ▬▬▬▬▬▬▬ 00:00 - Intro & What We Did in Previous TLS Video 00:35 - Why You MUST Use Cert-Manager in Real Production 02:05 - Install Cert-Manager (Controller, Webhook, CA Injector) 02:47 - Create ClusterIssuer + Auto-Generate TLS Certificate 06:42 - Attach Cert-Manager TLS Secret to Gateway API Listener 08:02 - Test HTTPS Gateway with Auto-Generated Certificates 08:33 - Summary, Automation Benefits & Next Video Preview For 1:1 mentorship, consultations, or career guidance, you can book a session with me here: 🔗 Watch Related Playlists: - Kubernetes: - Github Actions: - Ansible: - AWX: - AI: ▬▬▬▬▬▬ Connect with me 👋 ▬▬▬▬▬▬ LinkedIn: Website: Medium: @kumarnikhil811 #kubernetes #certmanager #tls #https #gatewayapi #ingress #security #devops
