| ## How it works | ||
|
|
||
| The Cloudformation template creates 2 S3 buckets (source and destination buckets) along with a Lambda function (Python) and an EventBridge event. The Lambda function is triggered by the EventBridge which listens to an object upload in the S3 bucket. The lambda function makes a DetectText API call to detect the text in an image and stores the output in the destination S3 bucket. |

These are old way of doing it. Use sam delete command. Also prior to deleting stack add commands to delete the contents from the bucket.

| This pattern demonstrates how to create an S3 bucket which when uploaded with an object invokes a Lambda function through EventBridge. The function detects the text in a document through Amazon Rekognition. The lambda function is built using Python. | |||

lambda function --> Lambda function

| Once you have run `sam deploy --guided` mode once and saved arguments to a configuration file (samconfig.toml), you can use `sam deploy` in future to use these defaults. | ||

| 1. Note the outputs from the SAM deployment process. These contain the resource names and/or ARNs which are used for testing. |
