Description

In this video, you’ll learn how to secure your web applications running on Kubernetes using HTTPS with TLS certificates issued by Let’s Encrypt. We walk through the complete setup, including installing Traefik as the ingress controller, setting up cert-manager, configuring DNS, and automating TLS certificate provisioning using the ACME protocol. Whether you’re deploying a staging or development environment, this tutorial follows a clean GitOps structure using Kustomize, making it easy to manage across environments. 🔧 What we cover: • Deploying sample apps on Kubernetes • Installing Traefik Ingress Controller • Setting up DNS records for your domain • Installing cert-manager for certificate management • Creating ClusterIssuer and issuing TLS certificates • Enabling HTTPS access via IngressRoute resources 📚 Resources GitHub repo: https://github.com/nsalexamy/secure-web-app-on-k8s-with-tls cert-manager docs: https://cert-manager.io/docs/ Traefik docs: https://doc.traefik.io/traefik/ Let’s Encrypt: https://letsencrypt.org/docs/ Subscribe for more Kubernetes GitOps and automation content!
