A technical walkthrough of Blue-Green Deployment using the Magnolia Operator — a Kubernetes operator that converts a single custom resource into a complete Magnolia deployment (author instance, public instances, and dedicated CNPG Postgres clusters). Covers database cloning via pg_basebackup, module cloning via init containers, RBAC setup, self-healing, spec-hash drift detection, and smart scaling — plus what's coming next (Backup & Restore, Gateway API).
