Creating a Lambda Function - AWS SDK for Ruby

Creating a Lambda Function

The following example creates the Lambda function named my-notification-function in the us-west-2 region using these values:

  • Role ARN: my-resource-arn. In most cases, you need to attach only the AWSLambdaExecute managed policy to the policy for this role.

  • Function entry point: my-package.my-class

  • Runtime: java8

  • Zip file: my-zip-file.zip

  • Bucket: my-notification-bucket

  • Key: my-zip-file
