Google Cloud Run API
Google Cloud Run API — deploy and manage containerized services that scale to zero, with automatic HTTPS, traffic splitting, and pay-per-use pricing.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
IAM-based service-to-service auth with identity tokens. Secret Manager integration for secrets injection. VPC connector for private network access. Binary Authorization for supply chain security. FedRAMP authorized.
⚡ Reliability
Best When
You want to deploy containerized agent services on GCP with zero infrastructure management, automatic scaling, and built-in HTTPS.
Avoid When
Your workloads are stateful, long-running (>60 min), or need persistent local storage.
Use Cases
- • Deploying agent microservices as Cloud Run services with automatic scaling to zero between requests
- • Running agent task workers as Cloud Run Jobs for batch processing with guaranteed completion
- • Managing multiple agent service versions with traffic splitting for blue/green deployments
- • Triggering Cloud Run Jobs from agent workflows for long-running compute tasks
- • Configuring Cloud Run service IAM and scaling policies programmatically from deployment pipelines
Not For
- • Long-running persistent workloads — Cloud Run instances time out; use GKE or Compute Engine
- • Stateful services needing local disk persistence — Cloud Run is stateless by design
- • Teams not on GCP — use AWS Lambda/ECS or Azure Container Apps for equivalent on other clouds
Interface
Authentication
Google service account or Application Default Credentials. run.admin scope for management; run.invoker for calling services. IAM at project/service level.
Pricing
Scales to zero means no charges when idle. Minimum instances option prevents cold starts but incurs constant cost.
Agent Metadata
Known Gotchas
- ⚠ Cold start latency (0-3 seconds) can impact agent workflows expecting consistent response times — use min-instances=1 for latency-sensitive services
- ⚠ Maximum request timeout is 60 minutes (3,600 seconds) — long-running tasks must use Cloud Run Jobs instead
- ⚠ Service-to-service authentication requires ID tokens, not service account keys — use metadata server for token
- ⚠ Container must listen on $PORT env var (not hardcoded port) — common misconfiguration
- ⚠ Cloud Run Jobs have different API surface than Services — separate endpoints for executions vs revisions
