terraform-scheduled-batch-job
A Terraform module representing a scheduled Batch job. Uses a Cloud Watch Event Rule and a Lambda function to submit the Batch job on a cron schedule. Use of the Batch service overcomes two of Lambda's current limitations:
- jobs can run longer than five minutes
- jobs run as containers so they can be written in any language
TODO: Consider including the Batch infrastructure setup inside this module once the Batch Terraform provider is available.
