You use Cloud Run and Cloud Source Repositories and have a Cloud Build YAML that builds the container and runs gcloud run deploy. What next step makes deployments most efficient?

The most efficient next step is to create a build trigger that automatically runs your Cloud Build YAML file whenever code is pushed to your development branch. This establishes a Continuous Integration/Continuous Deployment (CI/CD) pipeline, automating the build and deployment process directly from your source code changes. Creating a Pub/Sub topic and trigger is an indirect and less integrated approach for this specific use case; Cloud Build triggers handle repository events natively. A webhook trigger is useful for external systems initiating builds, but less direct for repository pushes. A Cron job for gcloud builds submit is a scheduled, manual-like approach, lacking the immediate, event-driven efficiency of a build trigger tied to source control.
