Deploying a schedule-based Serverless Strands Agent on AWS Lambda with CDK, EventBridge and Docker

Try It Yourself

Want to build your own agentic meme generator? Here's how to get started:

1. Clone the repository:

   git clone https://github.com/awsdataarchitect/agentic-meme-generator
   cd agentic-meme-generator

2. Install dependencies:

   pip install -r requirements.txt

3. Set up Twilio for WhatsApp messaging:

   • Sign up for a free Twilio account at https://www.twilio.com/try-twilio
   • Navigate to the Twilio Console and note down your Account SID and Auth Token
   • Enable the WhatsApp Sandbox in the Messaging section
   • Follow the instructions to connect your WhatsApp number to the sandbox by sending the provided code
   • Note: The sandbox allows you to send 9 free messages every 24 hours for testing

4. Configure your environment variables:

   export TWILIO_ACCOUNT_SID=your_account_sid
   export TWILIO_AUTH_TOKEN=your_auth_token
   export BEDROCK_WHATSAPP_TO=your_whatsapp_number  # Format: whatsapp:+1234567890

   You can test your Twilio setup with this simple Python script:

   from twilio.rest import Client
   
   client = Client("your_account_sid", "your_auth_token")
   message = client.messages.create(
       body="Test message from Twilio",
       from_="whatsapp:+14155238886",  # Twilio's sandbox number
       to="whatsapp:+1234567890"  # Your WhatsApp number
   )
   print(f"Message sent with SID: {message.sid}")

5. Deploy with CDK:

   cd agentic-meme-generator
   npm install
   npm run build
   cdk deploy

6. Trigger a meme generation manually on ad-hoc basis (if needed for testing):

   # Simpler approach using cli-binary-format
   aws lambda invoke \
     --region us-east-1 \
     --function-name AgenticMemeGenerator \
     --payload '{"body": "{\"theme\": \"standard\"}"}'  \
     --cli-binary-format raw-in-base64-out \
     /tmp/lambda-output.json
