Adk Deploy Guide

ADK Deployment Guide

Scaffolded project? Use make commands — they wrap Terraform, Docker, and deployment.

No scaffold? See Quick Deploy below. For production infrastructure, see the /scaffold-adk command or load the architecture-design skill for infrastructure planning.

Iron Law

NEVER create GCP resources manually via gcloud for production. Define all infrastructure in Terraform. Exception: quick experimentation only — console or gcloud for throwaway resources is fine.

Deployment Target Decision Matrix

Ask the user which target fits their needs before proceeding.

Quick Deploy (ADK CLI)

No Makefile, Terraform, or Dockerfile required.

# Cloud Run
adk deploy cloud_run --project=PROJECT --region=REGION path/to/agent/

# Agent Engine
adk deploy agent_engine --project=PROJECT --region=REGION path/to/agent/

Both support --with_ui to deploy the ADK dev UI. Cloud Run accepts extra gcloud flags after --.

Process

1. Gather requirements — target (Agent Engine vs Cloud Run), project ID, region, secrets needed
2. Choose target — use the decision matrix above; ask if unclear
3. Scaffold or write Terraform — run /scaffold-adk or manually write deployment/terraform/
4. Configure secrets — use Secret Manager, not env vars, for API keys and credentials
5. Deploy — make deploy (scaffolded) or adk deploy <target> (CLI)
6. Verify — health check endpoint, test with curl or testing notebook, run load tests

Secret Manager

# Create
echo -n "YOUR_API_KEY" | gcloud secrets create MY_SECRET_NAME --data-file=-

# Update
echo -n "NEW_KEY" | gcloud secrets versions add MY_SECRET_NAME --data-file=-

# Agent Engine: pass at deploy time
make deploy SECRETS="API_KEY=my-api-key,DB_PASS=db-password:2"

Grant secretmanager.secretAccessor to app_sa (Cloud Run) or service-PROJECT_NUMBER@gcp-sa-aiplatform-re.iam.gserviceaccount.com (Agent Engine).

Production Deployment — CI/CD Pipeline

Best for: Production applications, teams requiring staging → production promotion.

Prerequisites:

1. Project must NOT be in a gitignored folder
2. User must provide staging and production GCP project IDs
3. GitHub repository name and owner

Steps:

1. If prototype, first add Terraform/CI-CD files using the Agent Starter Pack CLI:

   uvx agent-starter-pack enhance . --cicd-runner github_actions -y -s
   

2. Ensure you're logged in to GitHub CLI:

   gh auth login  # (skip if already authenticated)
   

3. Run setup-cicd:

   uvx agent-starter-pack setup-cicd \
     --staging-project YOUR_STAGING_PROJECT \
     --prod-project YOUR_PROD_PROJECT \
     --repository-name YOUR_REPO_NAME \
     --repository-owner YOUR_GITHUB_USERNAME \
     --auto-approve \
     --create-repository
   

4. Push code to trigger deployments

Key setup-cicd Flags

Choosing a CI/CD Runner

How Authentication Works (WIF)

Both runners use Workload Identity Federation (WIF) — GitHub/Cloud Build OIDC tokens are trusted by a GCP Workload Identity Pool, which grants cicd_runner_sa impersonation. No long-lived service account keys needed. Terraform in setup-cicd creates the pool, provider, and SA bindings automatically. If auth fails, re-run terraform apply in the CI/CD Terraform directory.

CI/CD Pipeline Stages

The pipeline has three stages:

1. CI (PR checks) — Triggered on pull request. Runs unit and integration tests.
2. Staging CD — Triggered on merge to main. Builds container, deploys to staging, runs load tests.

   Path filter: Staging CD uses paths: ['app/**'] — it only triggers when files under app/ change. If nothing happens after the first push after setup-cicd, this is why.

3. Production CD — Triggered after successful staging deploy. May require manual approval before deploying to production.

   Approving: Go to GitHub Actions → the production workflow run → click "Review deployments" → approve the pending production environment. This is GitHub's environment protection rules.

IMPORTANT: setup-cicd creates infrastructure but doesn't deploy automatically. Push code to trigger the pipeline:

git add . && git commit -m "Initial agent implementation"
git push origin main

To approve production deployment:

# GitHub Actions: Approve via repository Actions tab (environment protection rules)

# Cloud Build: Find pending build and approve
gcloud builds list --project=PROD_PROJECT --region=REGION --filter="status=PENDING"
gcloud builds approve BUILD_ID --project=PROD_PROJECT

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). Needs permissions in both staging and prod projects.
