Managing TLS certificates across multi-tenant Kubernetes clusters can quickly become a friction point between platform engineering teams and developer teams. With the evolution of the Kubernetes Gateway API, the ListenerSet custom resource enables individual application teams to attach independent listeners to a shared Gateway. By pairing Gateway API ListenerSets with cert-manager (v1.20+) and...

Exposing a Model Context Protocol (MCP) server running on Azure Kubernetes Service (AKS) for team-wide or external use requires a robust production setup. While local port-forwarding works during early development, a production-grade infrastructure demands public domain routing, automated TLS certificate lifecycles, and identity-based access control. By combining the Kubernetes Gateway API, ce...

I am presenting a second session at The Hack Summit 2026! My session, “Set It and Forget It: Secure & Automated Certificate Management on AKS,” releases on November 5th, 2026 as an on-demand VOD presentation. With certificate lifespans continuously shrinking, manual certificate rotation is no longer just an inconvenience—it is a major operational liability that leads to unexpected producti...
