This Terraform module creates and uploads an AWS Lambda function and hides the ugly parts from you.

• Only appears in the Terraform plan when there are legitimate changes.
• Creates a standard IAM role and policy for CloudWatch Logs.
  • You can add additional policies if required.
• Zips up a source file or directory.
• Installs dependencies from requirements.txt for Python functions.
  • It only does this when necessary, not every time.

• Python 2.7 or higher
• Linux/Unix/Windows

module "lambda" {
  source = "github.com/claranet/terraform-aws-lambda"

  function_name = "deployment-deploy-status"
  description   = "Deployment deploy status task"
  handler       = "main.lambda_handler"
  runtime       = "python3.6"
  timeout       = 300

  // Specify a file or directory for the source code.
  source_path = "${path.module}/lambda.py"

  // Attach a policy.
  policy = data.aws_iam_policy_document.lambda.json

  // Add a dead letter queue.
  dead_letter_config {
    target_arn = aws_sqs_queue.dlq.arn
  }

  // Add environment variables.
  environment {
    variables {
      SLACK_URL = var.slack_url
    }
  }

  // Deploy into a VPC.
