## AI overview

This tutorial introduces sql-on-k8s-operator, an open-source Kubernetes operator for managing SQL Server workloads. It addresses high availability and disaster recovery by automating lifecycle management, failover, and Always On Availability Group setup, and demonstrates deployment with custom resources.

## Source excerpt

Are you considering replatforming your SQL Server workload due to recent vendor changes, but still need high availability and disaster recovery? You're not alone. One of the challenges with running SQL Server on Kubernetes is that there's no Kubernetes operator available. That means no automated lifecycle management, no automatic failover, and no standard way to bootstrap an Always On Availability Group on Kubernetes. I'm excited to share it today as an open-source project: sql-on-k8s-operator. Let's go.
