Scheduled AWS Lambda function

=============================

This module is used to provision AWS Lambda outside VPC to run on a schedule. This will create:

• One CloudWatchEvent
• Lambda function
• IAM Role assigned to the lambda with the following policies attached: AWSLambdaBasicExecutionRole. You could add other policy that the lambda needs.

Module Input Variables

• region - Region where the lambda is deployed. The default is ap-southeast-1
• lambda_code_bucket - The name of the s3 bucket where the deployment resides
• lambda_code_path - Name of the S3 deployment object
• lambda_name - Unique name for Lambda function
• lambda_runtime - A valid Lambda runtime environment
• lambda_handler - The entrypoint into your Lambda function
• lambda_memory_size - The memory size allocated to your lambda function
• tags - Tags associated with the lambda function
• environment_variables - Environment variables for your lambda function
• iam_policy_document - Additional IAM policy document to be attached to your lambda if the lambda needs to access another AWS resource.
• schedule_expression - a valid rate or cron expression

Usage

data "aws_iam_policy_document" "read-a-bucket" {
  statement {
    sid    = "AllowReadOfABucket"
    effect = "Allow"

    actions = [
      "s3:GetObject",
    ]

    resources = [
      "arn:aws:s3:::public-bucket/*",
    ]
  }
}

module "periodic_worker" {
  source = "git::ssh://[email protected]/terraform-aws-periodic-worker-vpc.git?ref=[version]"

  lambda_code_bucket = "tools-infra-lambda-bucket"

  lambda_code_path = "dummy.zip"

  lambda_name = "alambda"

  lambda_runtime = "nodejs6.10"

  lambda_handler = "lib.default"

  lambda_memory_size = "128"

  lambda_timeout = "300"

  require_additional_policy = true

  tags = {
    "team"   = "someteam"
    "domain" = "somedomain"
  }

  schedule_expression = "cron(*/10 * * * ? *)"

  iam_policy_document = "${data.aws_iam_policy_document.read-a-bucket.json}"
}

Outputs

• lambda_arn - ARN for the created Lambda function
• role_arn - ARN of the IAM role assigned to the lambda
