Terraform module to create a cron based lambda functions

What it does:

• Creates a role for lambda
• Creates and attaches policy to the role
• Creates Cloudwatch cron, connects it to lambda and grants permission to run lambda.
• Creates lambda function

Module Variables

• region - The AWS region. Defaults to us-east-1"
• enabled - bool, defaults to true
• lambda_name - Name for lambda function
• project - Project lambda belongs to
• runtime - Runtime for lambda function
• handler - Handler for lambda function
• lambda_zipfile - Path to zip file that contains lambda function
• source_code_hash - The hash for lambda Zip file"
• lambda_policy_document - Path to policy document for lambda function
• description - Description for lambda function
• timeout - Timeout for lambda function
• subnet_ids - The list of subnets functions belongs to
• security_group_ids - The list of security groups

Usage:

module "lambda_test" {    
    source              = "../../terraform/modules/aws_lambda_cron"
    lambda_name         = "test_inventory"
    runtime             = "python3.6"
    lambda_zipfile      = "${path.module}/function/function.zip"
    source_code_hash    = "${base64sha256(file("function/function.zip"))}"
    handler             = "redshift_inventory.lambda_handler"
    schedule_expression = "cron(0 */2 * * ? *)"
    policy_document     = "${file("policies/lambda-policy.json")}"

    # vpc_config parameters
    # don't set if you want lambda run off VPC
    # refer to terraform documentation
    # both variables are lists
    subnet_ids          = ["subnet-7e19af35"]
    security_group_ids  = ["sg-aa4519da"]
    # end vpc_config parameters

    project = "Infra"
    description = "Test function"
}

Outputs

• lambda_arn - the ARN for lmbda
• role_name - the NAME for the role
• role_arn - the ARN for role
