Terraform-Lambda

Quick module for spinning up a terraform and scheduling it to run periodically.

Due to limitations I couldn't figure out how to fix, if you don't set an environment variable it'll set a default one of "supersecretenvironmentvariable" = "thisisadefaultsetting".

Variables

Name	Type	Description	Notes
function_name	string	what it'll be called in AWS
lambda_handler	string
lambda_runtime	string	Python3.8 or whatever you want to run it in
aws_region	string
aws_profile	string
lambda_run_on_schedule	bool	Enable the schedule runner	Defaults to false
lambda_schedule_expression	string	When to run it via EventBridge	https://docs.aws.amazon.com/eventbridge/latest/userguide/scheduled-events.html
lambda_timeout	number	The maximum runtime in seconds
lambda_memory	number	The configured memory (in megabytes) the function's allowed to use
layer_arns	list(string)	A list of layer ARNs to include
lambda_script_filename	string	The original filename on the filesystem of the function
lambda_script_additional_files	list(string)	Additional files to include in the package.
environment_variables	map(string)	A map of environment variables	By default, it'll set "supersecretenvironmentvariable" = "thisisadefaultsetting"
log_retention_days	string	Number of days to keep the function logs	defaults to 1
