# Scheduled AWS Lambda function

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

This module can be used to deploy an AWS Lambda function which is scheduled to run on a recurring basis.

Module Input Variables

----------------------

- `lambda_name` - Unique name for Lambda function

- `memory_size` (optional) - Amount of memory in MB your Lambda Function can use at runtime. Defaults to 128.

- `runtime` - A [valid](http://docs.aws.amazon.com/cli/latest/reference/lambda/create-function.html#options) Lambda runtime environment

- `lambda_zipfile` - path to zip archive containing Lambda function

- `source_code_hash` - the base64 encoded sha256 hash of the archive file - see TF [archive file provider](https://www.terraform.io/docs/providers/archive/d/archive_file.html)

- `handler` - the entrypoint into your Lambda function, in the form of `filename.function_name`

- `schedule_expression` - a [valid rate or cron expression](http://docs.aws.amazon.com/lambda/latest/dg/tutorial-scheduled-events-schedule-expressions.html)

- `iam_policy_document` - a valid IAM policy document used for the Lambda's [execution role](http://docs.aws.amazon.com/lambda/latest/dg/intro-permission-model.html#lambda-intro-execution-role)

- `timeout` - (optional) the amount of time your Lambda Function has to run in seconds. Defaults to 3. See [Limits](https://docs.aws.amazon.com/lambda/latest/dg/limits.html)

- `subnet_ids` (optional) - If set, the lambda will be deployed inside a VPC on the subnet(s) specified. Expects a comma separated list of valid AWS subnet ids.

- `security_group_ids` (optional) - If set, the lambda will be deployed inside a VPC and use the security groups specified. Expects a comma separated list of valid VPC security group ids .

- `enabled` - boolean expression. If false, the lambda function and the cloudwatch schedule are not set. Defaults to `true`.

Usage 

-----

```js

data "aws_iam_policy_document" "create_snaps" {

  statement {

    sid = "1"

    actions = [

      "ec2:DescribeVolumes",

      "ec2:CreateSnapshot",

      "ec2:CreateTags",

    ]

    resources = [

      "*",

    ]

  }

}

data "archive_file" "myfunction" {

  type        = "zip"

  source_file = "/valid/path/to/myfunction.py"

  output_path = "/valid/path/to/myfunction.zip"

}

module "lambda_scheduled" {

  source              = "github.com/terraform-community-modules/tf_aws_lambda_scheduled"

  lambda_name         = "my_scheduled_lambda"

  runtime             = "python2.7"

  lambda_zipfile      = "/valid/path/to/myfunction.zip"

  source_code_hash    = "${data.archive_file.myfunction.output_base64sha256}"

  handler             = "myfunction.handler"

  schedule_expression = "rate(1 day)"

  iam_policy_document = "${data.aws_iam_policy_document.create_snaps.json}"

}

```

Outputs

-------

- `lambda_arn` - ARN for the created Lambda function
