A walkthrough of setting up TLS/HTTPS on Kubernetes using cert-manager with the Gateway API and Let's Encrypt. Covers installing cert-manager via Helm, configuring DNS with Cloudflare, and using the HTTP-01 ACME challenge to automatically provision certificates. The process involves creating a ClusterIssuer pointing to Let's Encrypt, defining a Certificate resource, and letting cert-manager handle the HTTP route and challenge flow to generate a valid Kubernetes TLS secret.
