Terraform-AWS-Lambda-Janitor

Clean up unused Lambda function in the current AWS Account.

Based upon Yan Cui's Lambda Janitor

In order to keep within the 75G limit of Lambda function code storage, this function removes unused function versions.

A version is defined to be unused if it:

  • Isn't $LATEST
  • Isn't referenced by a function Alias

The function is configured to run according to a schedule. By default this is at 3am UTC, however the schedule is configurable with the schedule_expression parameter.

Example Usage

module "janitor" {
  source = "git@github.com:barneyparker/terraform-aws-lambda-janitor.git?ref=v1.0.0"

  name = "Janitor"
}

Parameters

Name Description Required Default
name Lambda function name Yes
schedule_expression CloudWatch Cron schedule expression No cron(0 3 * * ? *)
log_retention Retention in days for CloudWatch Logs No 7
boundary_policy Boundary policy ARN No null

Attributes

None
