SQL Server 2025 rolls out spinvokeexternalrestendpoint, a new way to hit REST APIs straight from T-SQL. That includes calling the Kubernetes API—thanks to a reverse proxy in front.

The setup’s not exactly plug-and-play. You’ll need custom TLS certs, an nginx reverse proxy, and Kubernetes RBAC to keep things locked down while letting SQL talk to the cluster.

Bigger picture: SQL Server’s not just crunching rows anymore. It’s stepping into systems integration—wiring data logic into orchestrators like Kubernetes.
