In this video, we continue the tutorials on the Jets Ruby Serverless Framework that adds Ruby support to AWS Lambda. We’ll demonstrate how to customize the properties associated with the Lambda functions that Jets creates. There are 3 ways to set function properties with Jets: at the function level, class level or application level. We’ll also explore the AWS Lambda console and shows how the Lambda function properties connect with Jets.

Here’s a list of the properties you can adjust.

  • dead_letter_config
  • description
  • environment
  • handler
  • kms_key_arn
  • memory_size
  • reserved_concurrent_executions
  • role
  • runtime
  • timeout
  • tracing_config
  • vpc_config
  • tags

For more info, refer to the Function Properties docs.
