Cloud Run: IAP integration and DRS-compatible public access
🔒 Cloud Run now supports direct Identity-Aware Proxy (IAP) integration and a new option to allow public access compatible with Domain Restricted Sharing. Enable IAP with a single click or via the --iap flag without provisioning load balancers, bringing context-aware, enterprise-grade authentication to serverless apps at no added load balancer cost. The 'Allow Public access' toggle disables the IAM invoker check to support public websites or private microservices that rely on network-level or organizational controls, and IAP’s CORS handling permits unauthenticated OPTIONS for preflight while authenticating other requests.
