Deploy Lambda into VPC or outside of the VPC.

Usage example

Here's the gist of using it via github.

module "lambda" {
  source  = "terraform-module/lambda/aws"
  version = "~> 2"

  function_name      = "lambda-name-to-deploy"
  filename            = "${path.module}/lambda.zip"
  description        = "description should be here"
  handler            = "index.handler"
  runtime            = "nodejs12.x"
  memory_size        = "128"
  concurrency        = "5"
  lambda_timeout     = "20"
  log_retention      = "1"
  role_arn           = "some-role-arn"
  tracing_config      = { mode = "Active" }

  vpc_config = {
    subnet_ids         = ["sb-q53asdfasdfasdf", "sf-3asdfasdfasdf6"]
    security_group_ids = ["sg-3asdfadsfasdfas"]
  }

  environment = {
    Environment = "test"
  }

  tags = {
    Environment = "test"
  }
}

Inputs

Name	Description	Type	Default	Required
concurrency	The amount of reserved concurrent executions for this lambda function. A value of 0 disables lambda from being triggered and -1 removes any concurrency limitations.	number	n/a	yes
description	Description of what your Lambda Function does.	string	n/a	yes
environment	The Lambda environment's configuration settings.	map(string)	null	no
event_age_in_seconds	Maximum age of a request that Lambda sends to a function for processing in seconds. Valid values between 60 and 21600.	number	100	no
filename	The path to the function's deployment package within the local filesystem. If defined. No S3 support	string	n/a	yes
function_name	A unique name for your Lambda Function.	string	n/a	yes
handler	The function entrypoint in your code.	string	n/a	yes
lambda_timeout	The amount of time your Lambda Function has to run in seconds. Defaults to 5	number	5	no
layers	List of Lambda Layer Version ARNs (maximum of 5) to attach to your Lambda Function	list(string)	null	no
log_retention	Specifies the number of days you want to retain log events in the specified log group.	number	1	no
memory_size	Amount of memory in MB your Lambda Function can use at runtime. Defaults to 128.	number	n/a	yes
publish	Whether to publish creation/change as new Lambda Function Version. Defaults to true.	bool	true	no
retry_attempts	Maximum number of times to retry when the function returns an error. Valid values between 0 and 2. Defaults to 0.	number	0	no
role_arn	IAM role attached to the Lambda Function. This governs both who / what can invoke your Lambda Function, as well as what resources our Lambda Function has access to.	string	n/a	yes
runtime	See Runtimes for valid values.	string	n/a	yes
source_code_hash	Used to trigger updates when file contents change. Must be set to a base64-encoded SHA256 hash of the package file specified with either filename or s3_key.	string	null	no
tags	A mapping of tags to assign to the object.	map	{}	no
tracing_config	Use AWS X-Ray to collect data about events that your function processes, and to identify the cause of errors in your serverless applications. Can be either PassThrough or Active.	object({ mode = string })	null	no
vpc_config	Provide this to allow your function to access your VPC. Fields documented below. See Lambda in VPC.	object({ security_group_ids = list(string) subnet_ids = list(string) })	null	no
file_system_config	Provide this to allow your function to mount your EFS file system. Fields documented below. See Lambda with EFS.	{ efs_access_point_arn = string local_mount_path = string }	null	no
