Explain the deployment options for Google ADK agents (Vertex AI, Cloud Run, GKE, Docker).

Deploying Google ADK Agents

Google ADK agents can be deployed across multiple platforms from fully managed to self-hosted.

Deployment Options

1. Vertex AI Agent Engine (Recommended for Production)

pythonCopy
from google.adk.agents import Agent

agent = Agent(
    name="prod_agent",
    model="gemini-2.5-flash",
    instruction="You are a production assistant.",
    tools=[search_documents],
)

# Deploy to Vertex AI
# adk deploy vertex --project=my-project --region=us-central1

2. Google Cloud Run

pythonCopy
# Dockerfile
# FROM python:3.12-slim
# WORKDIR /app
# COPY . .
# RUN pip install google-adk
# CMD ["adk", "api_server", "--port", "8080", "my_agent"]

bashCopy
# Build and deploy
docker build -t my-agent .
gcloud run deploy my-agent \
    --image gcr.io/PROJECT_ID/my-agent \
    --platform managed \
    --region us-central1 \
    --allow-unauthenticated \
    --set-env-vars GOOGLE_API_KEY=your-key

3. Google Kubernetes Engine (GKE)

yamlCopy
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: adk-agent
spec:
  replicas: 3
  selector:
    matchLabels:
      app: adk-agent
  template:
    metadata:
      labels:
        app: adk-agent
    spec:
      containers:
      - name: agent
        image: gcr.io/PROJECT_ID/my-agent
        ports:
        - containerPort: 8080
        env:
        - name: GOOGLE_API_KEY
          valueFrom:
            secretKeyRef:
              name: api-keys
              key: google-api-key

bashCopy
kubectl apply -f deployment.yaml
kubectl apply -f service.yaml

4. Docker (Self-Hosted)

bashCopy
# Build
docker build -t my-agent .

# Run locally
docker run -p 8080:8080 \
    -e GOOGLE_API_KEY=your-key \
    my-agent

# Or with docker-compose
docker compose up

5. Local Development

bashCopy
# Terminal interaction
adk run my_agent

# Web UI development
adk web my_agent

# API server
adk api_server my_agent --port 8080
