| description | This skill should be used when the user wants to "deploy an agent", "deploy my ADK agent", "set up CI/CD", "configure secrets", "troubleshoot a deployment", or needs guidance on Agent Runtime, Cloud Run, or GKE deployment targets, or awareness of Agent Gateway. Covers deployment workflows, service accounts, rollback, and production infrastructure. Part of the Google ADK (Agent Development Kit) skills suite. Do NOT use for API code patterns (use google-agents-cli-adk-code), evaluation (use google-agents-cli-eval), or project scaffolding (use google-agents-cli-scaffold).

ADK Deployment Guide
Requires: agents-cli (uv tool install google-agents-cli) — install uv first if needed.
Prefer using the agents-cli commands throughout this guide — they wrap Terraform, Docker, and deployment into a tested pipeline. If your project isn't scaffolded yet, see /google-agents-cli-scaffold to add deployment support first.

Deployment Target Decision Matrix
Choose the right deployment target based on your requirements:
| Criteria | Agent Runtime | Cloud Run | GKE |
|---|
| Scaling | Managed auto-scaling (configurable min/max, concurrency) | Fully configurable (min/max instances, concurrency, CPU allocation) | Full Kubernetes scaling (HPA, VPA, node auto-provisioning) |
| Networking | VPC-SC and PSC-I supported (private VPC connectivity via network attachments) | Full VPC support, direct VPC egress, IAP, ingress rules | Full Kubernetes networking |
| Session state | Native VertexAiSessionService (persistent, managed) | In-memory (dev), Cloud SQL, or Agent Platform Sessions backend | In-memory (dev), Cloud SQL, or Agent Platform Sessions backend |
| Batch/event processing | Trigger endpoints reachable via the Agent Engine /api passthrough | Native trigger endpoints (Pub/Sub, Eventarc); see /google-agents-cli-adk-code | Custom (Kubernetes Jobs, Pub/Sub) |
| Cost model | vCPU-hours + memory-hours (not billed when idle) | Per-instance-second + min instance costs | Node pool costs (always-on or auto-provisioned) |
| Setup complexity | Lower (managed, purpose-built for agents) | Medium (Dockerfile, Terraform, networking) | Higher (Kubernetes expertise required) |
| Best for | Managed infrastructure, minimal ops | Custom infra, full networking control | Full Kubernetes control |
Ask the user which deployment target fits their needs. Each is a valid production choice with different trade-offs.
All three targets are container-based, so any language works.
Product name mapping: "Agent Engine" / "Vertex AI Agent Engine" is now Agent Runtime. Use --deployment-target agent_runtime.
Ambient / scheduled / event-driven agents: ADK's trigger_sources registers /apps/{app}/trigger/* endpoints on the same FastAPI app for all targets. On Cloud Run / GKE these are public HTTP routes you point a Pub/Sub push subscription or Eventarc trigger at; on Agent Runtime the same routes are reachable through the Agent Engine /api passthrough (e.g. .../reasoningEngines/v1/{resource}/api/apps/{app}/trigger/pubsub). Cloud Run remains the simplest target for unauthenticated trigger sources. See /google-agents-cli-adk-code (references/adk-python.md, section "12. Event-Driven / Ambient Agents") for the trigger_sources pattern.
OAuth / user consent agents: Use Agent Runtime with Gemini Enterprise for agents that need OAuth 2.0 user consent (e.g., accessing Google Drive, Calendar, or other user-scoped APIs). Cloud Run does not currently support managed OAuth flows. See the adk-ae-oauth sample in the /google-agents-cli-workflow sample catalog (Phase 1).
Deploying to Dev
Deploy Workflow
Task tracking: Deployment involves multiple sequential steps (infra setup, CI/CD configuration, deploy, verification). Use a task list to track progress through these steps — skipping one often causes failures in later steps that are hard to trace back.
- If prototype (no deployment target), first enhance:
agents-cli scaffold enhance . --deployment-target <target>
- Notify the human: "Eval scores meet thresholds and tests pass. Ready to deploy to dev?"
- Wait for explicit approval
- Once approved:
agents-cli deploy
Agent Runtime timeout recovery: Agent Runtime deploys can take 5-10 minutes and may exceed command timeouts. If the deploy command is cancelled or times out, the deployment continues server-side. Run agents-cli deploy --status to check progress — poll every 60 seconds until it reports completion or failure.
IMPORTANT: Never run agents-cli deploy without explicit human approval.
Do NOT run agents-cli infra single-project before deploying. It is not a prerequisite — agents-cli deploy works on its own. Run it separately if the user needs observability features (prompt-response logging, BigQuery analytics) — see /google-agents-cli-observability.
Single-Project Infrastructure Setup (Optional — Advanced)
agents-cli infra single-project runs terraform apply in deployment/terraform/single-project/. Use this to provision single-project GCP infrastructure without CI/CD (service accounts, IAM bindings, telemetry resources, Artifact Registry). Also useful to test things in a single project before going to production. It is NOT required for deploying.
agents-cli infra single-project
Note: agents-cli deploy doesn't automatically use the Terraform-created app_sa. Pass the service account explicitly: agents-cli deploy --service-account SA_EMAIL.
Deploy Flag Reference
| Flag | Description | Targets |
|---|
--project | GCP project ID | All |
--region | GCP region | All |

Run agents-cli deploy --help for the full flag reference.
Advanced Cloud Run Deploys: If you need features not exposed via agents-cli flags, use --dry-run (or -n) to print the full gcloud command, copy it, and add additional arguments as needed.
Project Confirmation: If the project is resolved automatically (not passed via --project), the command will prompt for confirmation in interactive mode. Since agents typically run in non-interactive mode, you MUST pass --no-confirm-project to proceed if you are relying on automatic project resolution.
Sizing a deployment
Defaults (same on Agent Runtime, Cloud Run, and the generated service.tf): --cpu 1, --memory 4Gi, --concurrency 8, --min-instances 1, --max-instances 10.
The params are coupled — scale them together:
- One async process — scale out, not up. The container runs a single
uvicorn process that serves many requests concurrently on the event loop, so throughput comes from --concurrency and horizontal scale (--max-instances), not extra worker processes. Raise --cpu only if profiling shows the event loop or synchronous tool calls are CPU-bound.
- Memory bounds concurrency. Each concurrent request keeps its full working set (context window, history, RAG chunks, response buffer) in memory while it waits on the model, so peak ≈ base +
concurrency × per-request memory. Memory — not CPU — is the first limit, so raising --concurrency without --memory is the main OOM cause.
- Concurrency default is conservative. An async worker can serve many concurrent requests while it waits on the model, but per-request memory is agent-specific, so
8 protects a memory-heavy (RAG/multimodal) agent. Light agents can raise it to 16–32+ after load-testing. See Underutilized asynchronous workers.
agents-cli deploy --cpu 4 --concurrency 16 --memory 16Gi --max-instances 20
Tune with the scaffolded load test (tests/load_test/, run locally or in the CI/CD staging pipeline): drive load, watch max latency and memory/OOM restarts, then adjust — high max latency → raise concurrency (+ workers/cpu); OOM → raise memory or lower concurrency.
On GKE these sizing flags are rejected — size via the Terraform manifests + HorizontalPodAutoscaler under deployment/terraform/.
Production Deployment — CI/CD Pipeline
For the full CI/CD pipeline setup guide — prerequisites, infra cicd flags, runner comparison, WIF authentication, pipeline stages, and production approval — see references/cicd-pipeline.md.
Cloud Run Specifics
For detailed infrastructure configuration (scaling defaults, Dockerfile, FastAPI endpoints, session types, networking), see references/cloud-run.md. For ADK docs on Cloud Run deployment, fetch https://adk.dev/deploy/cloud-run/index.md.
For event-driven / ambient agent deployment on Cloud Run, see the ambient-expense-agent sample and /google-agents-cli-adk-code (references/adk-python.md, section "12. Event-Driven / Ambient Agents") for the trigger_sources pattern.
Agent Runtime Specifics
Agent Runtime is a managed Vertex AI service for deploying Python ADK agents. Uses container-based deployment: agents-cli deploy packages your project and Agent Engine builds the image from your project's Dockerfile (required) — the same fast_api_app:app image that serves Cloud Run and GKE.
No gcloud CLI exists for Agent Runtime. Deploy via agents-cli deploy. Query via the Python vertexai.Client SDK.
Deployments can take 5-10 minutes. Use --no-wait to start a deployment and return immediately, then check on it later with --status:
agents-cli deploy --no-wait
agents-cli deploy --status
When --status detects the operation has completed, it writes deployment_metadata.json and prints the same success output as a normal deploy.
For detailed infrastructure configuration (container deploy flow, the unified FastAPI app and /api passthrough, Terraform resource, deployment metadata, session/artifact services, CI/CD differences), see references/agent-runtime.md. For ADK docs on Agent Runtime deployment, fetch https://adk.dev/deploy/agent-runtime/index.md.
GKE Specifics
For detailed infrastructure configuration (Kubernetes manifests, Terraform resources, Workload Identity, session types, networking), see references/gke.md. For ADK docs on GKE deployment, fetch https://adk.dev/deploy/gke/index.md.
Service Account Architecture
Scaffolded projects use two service accounts:
app_sa (per environment) — Runtime identity for the deployed agent. Roles defined in deployment/terraform/iam.tf.cicd_runner_sa (CI/CD project) — CI/CD pipeline identity (GitHub Actions / Cloud Build). Lives in the CI/CD project (defaults to prod project), needs permissions in both staging and prod projects.
Check deployment/terraform/iam.tf for exact role bindings. Cross-project permissions (Cloud Run service agents, artifact registry access) are also configured there.
Common 403 errors:
- "Permission denied on Cloud Run" →
cicd_runner_sa missing deployment role in the target project
- "Cannot act as service account" → Missing
iam.serviceAccountUser binding on app_sa
- "Secret access denied" →
app_sa missing secretmanager.secretAccessor
- "Cloud SQL connection failed / Not authorized" → Runtime service account missing
roles/cloudsql.client
- "Artifact Registry read denied" → Cloud Run service agent missing read access in CI/CD project
Required Permissions for CI/CD Setup
roles/secretmanager.admin granted to the Cloud Build service account (service-<PROJECT_NUMBER>@gcp-sa-cloudbuild.iam.gserviceaccount.com) in the CI/CD project. This allows Cloud Build to access the GitHub token stored in Secret Manager.
Required APIs
The following Google Cloud APIs must be enabled in your project for the skills and deployment to work:
cloudbuild.googleapis.com — Required for building container images and running CI/CD pipelines.secretmanager.googleapis.com — Required for managing secrets and API keys.run.googleapis.com — Required for deploying to Cloud Run.
Ensure these are enabled before running deployment or CI/CD setup commands:
gcloud services enable cloudbuild.googleapis.com secretmanager.googleapis.com run.googleapis.com --project=YOUR_PROJECT_ID
Secret Manager (for API Credentials)
Instead of passing sensitive keys as environment variables, use GCP Secret Manager.
echo -n "YOUR_API_KEY" | gcloud secrets create MY_SECRET_NAME --data-file=-
echo -n "NEW_API_KEY" | gcloud secrets versions add MY_SECRET_NAME --data-file=-
Grant access: For Cloud Run, grant secretmanager.secretAccessor to app_sa. For Agent Runtime, grant it to the platform-managed SA (service-PROJECT_NUMBER@gcp-sa-aiplatform-re.iam.gserviceaccount.com). For GKE, grant secretmanager.secretAccessor to app_sa. Access secrets via Kubernetes Secrets or directly via the Secret Manager API with Workload Identity.
Pass secrets at deploy time (Agent Runtime, Cloud Run):
agents-cli deploy --secrets "API_KEY=my-api-key,DB_PASS=db-password:2"
Format: ENV_VAR=SECRET_ID or ENV_VAR=SECRET_ID:VERSION (defaults to latest). Access in code via os.environ.get("API_KEY").
Cloud SQL Permissions (Manual Deployment)
When using Cloud SQL with Cloud Run in a manual deployment (e.g., adding --add-cloudsql-instances in non-Terraform setups), you must manually grant the Cloud SQL Client role to the runtime service account.
Without this, the deployment may succeed but fail at runtime with cloudsql.instances.get authorization errors.
gcloud projects add-iam-policy-binding YOUR_PROJECT_ID \
--member="serviceAccount:YOUR_RUNTIME_SA_EMAIL" \
--role="roles/cloudsql.client"
Note: In full Terraform-managed setups (infra cicd / infra single-project), this role is configured and managed automatically.
Observability
See the agents-cli-observability skill for observability configuration (Cloud Trace, prompt-response logging, BigQuery Analytics, third-party integrations).
Testing Your Deployed Agent
The quickest way to test a deployed agent is agents-cli run --url <service-url> --mode <a2a|adk> "your prompt" — it handles auth, sessions, and streaming automatically (supports Agent Runtime and Cloud Run).
For advanced testing (custom headers, session reuse, scripting, load tests), see references/testing-deployed-agents.md.
Deploying with a UI (IAP)
IAP (Identity-Aware Proxy) secures a Cloud Run service so only authorized Google accounts can access it. Enable it by adding the --iap flag when deploying (Cloud Run only): agents-cli deploy --iap.
For Agent Runtime with a custom frontend, use a decoupled deployment — deploy the frontend separately to Cloud Run or Cloud Storage, connecting to the Agent Runtime backend API.
For more information on IAP with Cloud Run, see the Cloud Console IAP settings.
Rollback & Recovery
The primary rollback mechanism is git-based: fix the issue, commit, and push to main. The CI/CD pipeline will automatically build and deploy the new version through staging → production.
For immediate Cloud Run rollback without a new commit, use revision traffic shifting:
gcloud run revisions list --service=SERVICE_NAME --region=REGION
gcloud run services update-traffic SERVICE_NAME \
--to-revisions=REVISION_NAME=100 --region=REGION
Agent Runtime doesn't support revision-based rollback — fix and redeploy via agents-cli deploy.
For GKE rollback, use kubectl rollout undo:
kubectl rollout undo deployment/DEPLOYMENT_NAME -n NAMESPACE
kubectl rollout status deployment/DEPLOYMENT_NAME -n NAMESPACE
Custom Infrastructure (Terraform)
CRITICAL: When your agent requires custom infrastructure (Cloud SQL, Pub/Sub, Eventarc, BigQuery, etc.), you MUST define it in Terraform — never create resources manually via gcloud commands. Exception: quick experimentation is fine with gcloud or console, but production infrastructure must be in Terraform.
For custom infrastructure patterns, consult references/terraform-patterns.md for:
- Where to put custom Terraform files (single-project vs CI/CD)
- Resource examples (Pub/Sub, BigQuery, Eventarc triggers)
- IAM bindings for custom resources
- Terraform state management (remote vs local, importing resources)
- Common infrastructure patterns
Troubleshooting
| Issue | Solution |
|---|
| Terraform state locked | terraform force-unlock -force LOCK_ID in deployment/terraform/ |
| GitHub Actions auth failed | Re-run terraform apply in CI/CD terraform dir; verify WIF pool/provider |
| Cloud Build authorization pending | Use github_actions runner instead |
| Resource already exists | terraform import (see references/terraform-patterns.md) |
| Agent Runtime deploy timeout / hangs | Deployments take 5-10 min; check if engine was created (see Agent Runtime Specifics) |
| Secret not available | Verify secretAccessor granted to app_sa (not the default compute SA) |
| Cloud SQL connection failed / 403 | Grant roles/cloudsql.client to the runtime service account when using manual deployments |
| 403 on deploy | Check deployment/terraform/iam.tf — cicd_runner_sa needs deployment + SA impersonation roles in the target project |
| 403 when testing Cloud Run | Default is --no-allow-unauthenticated; include Authorization: Bearer $(gcloud auth print-identity-token) header |
| Cold starts too slow | Set min_instance_count > 0 in Cloud Run Terraform config |
| Cloud Run 503 errors | Check resource limits (memory/CPU), increase max_instance_count, or check container crash logs |
| 403 right after granting IAM role | IAM propagation is not instant — wait a couple of minutes before retrying. Don't keep re-granting the same role |
| Resource seems missing but Terraform created it | Run terraform state list to check what Terraform actually manages. Resources created via null_resource + local-exec (e.g., BQ linked datasets) won't appear in gcloud CLI output |
| Deployment failed or agent not responding | Check Cloud Logging: gcloud logging read "resource.type=cloud_run_revision AND resource.labels.service_name=SERVICE" --project=PROJECT --limit=50 --format="table(timestamp,severity,textPayload)" for Cloud Run, or gcloud logging read "resource.type=aiplatform.googleapis.com/ReasoningEngine" --project=PROJECT --limit=50 for Agent Runtime |
| Agent returns errors after deploy | Open Cloud Logging in Console → filter by service name (Cloud Run) or reasoning engine resource (Agent Runtime) → look for Python tracebacks or permission errors in recent log entries |
Platform Registration
For registering deployed agents with Gemini Enterprise, see /google-agents-cli-publish.
Agent Gateway & Semantic Governance (Gemini Enterprise Agent Platform)
Note: There are no agents-cli commands for these yet. Deploy your agent as usual
with agents-cli deploy, then configure Agent Gateway and Semantic Governance separately
(via Terraform or the Cloud Console).
Agent Gateway is the networking + security entry/exit point for all agent interactions
(user↔agent, agent↔tool, agent↔agent) — it centralizes access control and governed
connectivity (ingress/egress). It is not a deployment target. Deploy your agent with
agents-cli deploy, then attach it to a gateway one of two ways:
Background: Agent Gateway overview.
Semantic Governance Policies (SGP) add a natural-language security/compliance layer
that keeps an agent's tool invocations aligned with user intent and organizational
constraints.
