• check mapping curl ES_DOMAIN/item

• check item curl ES_DOMAIN/item/_search

Deploy the sample application

The Serverless Application Model Command Line Interface (SAM CLI) is an extension of the AWS CLI that adds functionality for building and testing Lambda applications. It uses Docker to run your functions in an Amazon Linux environment that matches Lambda. It can also emulate your application's build environment and API.

To use the SAM CLI, you need the following tools.

• SAM CLI - Install the SAM CLI
• Python 3 installed
• Docker - Install Docker community edition

To build and deploy your application for the first time, run the following in your shell:

sam build --use-container
sam deploy --guided

Use the SAM CLI to build and test locally

Build your application with the sam build --use-container command.

sam-bom1$ sam build --use-container

Run functions locally and invoke them with the sam local invoke command.

sam local invoke HelloWorldFunction --event events/event.json

The SAM CLI can also emulate your application's API. Use the sam local start-api to run the API locally on port 3000.

sam local start-api
http://localhost:3000/

Fetch, tail, and filter Lambda function logs

sam logs -n HelloWorldFunction --stack-name sam-bom1 --tail

Cleanup

To delete the sample application that you created, use the AWS CLI. Assuming you used your project name for the stack name, you can run the following:

aws cloudformation delete-stack --stack-name sam-bom1
