Running databases on Kubernetes is now the norm. However, when scale threatens your compliance and security model across a large fleet of databases, a modern policy engine like Kyverno becomes essential. Join contributors from the Kyverno and CloudNativePG projects to see how these CNCF projects can work together to manage PostgreSQL databases on Kubernetes with enhanced security, governance, and validation of recommended patterns. We will showcase practical examples of using Kyverno to enforce security standards, validate configurations, and streamline self-service database provisioning for your application teams, making your Kubernetes-native Postgres fleet secure and compliant by design.
