Ringed Deployments with Azure Developer CLI

This article details a ringed deployment pipeline built with Azure Developer CLI (azd), Bicep, Helm, and ArgoRollouts to enable safe progressive delivery for Kubernetes workloads. The author shares their experience building a Fan Intelligence proof-of-technology for the FIFA World Cup 2026, emphasizing the need for automated rollbacks, health-check gated canary releases, and a full audit trail. The pipeline replaces manual kubectl apply with a structured flow: azd provisions infrastructure per region, then deploys the app incrementally through canary stages (5%, 25%, 100%) with automated rollback on error spikes. The pattern is platform-agnostic and reusable for any AKS-based service requiring safe deployments.
