Manual certificate rotation has become a significant operational liability. In an era of shrinking certificate lifespans and increasing cluster complexity, traditional manual methods are no longer a viable way to maintain production uptime. Automation has transitioned from a luxury to a fundamental security requirement for modern cloud-native environments.

This session breaks down the implementation of a modern "Gold Standard" for certificate management on Azure Kubernetes Service, explaining the mechanics of both HTTP-01 and DNS-01 validation challenges while detailing the practical differences between specific and wildcard certificates.

The presentation demonstrates a secure, zero-secret identity model using Azure Workload Identity to grant Cert-Manager access to Azure DNS without managing long-lived credentials.

Attendees will gain a technical understanding of the mechanics behind the DNS-01 challenge and why it is the essential method for issuing wildcard certificates. The discussion also covers how to configure automated renewals and on-demand provisioning, enabling advanced workflows such as dynamic certificate creation for ephemeral environments during pull request deployments.

By the end of the session, participants will have the specific technical knowledge required to integrate these automated systems with both Ingress and the Gateway API, allowing them to build and maintain a fully automated, hands-off certificate lifecycle.
