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

require 'aws-sdk-lambda' # v2: require 'aws-sdk' client = Aws::Lambda::Client.new(region: 'us-west-2') args = {} args[:role] = 'my-resource-arn' args[:function_name] = 'my-notification-function' args[:handler] = 'my-package.my-class' # Also accepts nodejs, nodejs4.3, and python2.7 args[:runtime] = 'java8' code = {} code[:zip_file] = 'my-zip-file.zip' code[:s3_bucket] = 'my-notification-bucket' code[:s3_key] = 'my-zip-file' args[:code] = code client.create_function(args)
