This Terraform module sets up an AWS Lambda function that sends an email via Amazon SES whenever a new object is created in a specified S3 bucket.
I saw this conversation on the AWS Reddit about this topic and realized I'd also benefit greatly from such a tool.
My use case is to save time reading the CSV daily business report files "conveniently" dropped into an S3 bucket by the AWS Marketplace, where I'm selling some AWS cost optimization tools.
Previously I had to log in using MFA, go to S3, find the bucket, browse to the file, etc, which took a loooong time.
I spent a few hours building this (with plenty of help from ChatGPT), but now that I have this, the file I'm interested in is delivered by email immediately and I just need to open it in a few seconds.
The email looks like this:
module "email_sender" {
source = "LeanerCloud/email-files-dropped-in-s3/aws"
version = "0.0.3"
bucket_name = "my-s3-bucket"
email_from = "sender@example.com"
email_to = "recipient@example.com"
kms_key_arn = "arn:aws:kms:us-east-1:xxxxxxxxxxxx:key/yyyyyyyyyyyyyyyyy"
}| Name | Description | Type | Default | Required |
|---|---|---|---|---|
| bucket_name | The name of the S3 bucket that will trigger the Lambda function | string |
n/a | yes |
| email_from | The email address of the sender | string |
n/a | yes |
| email_to | The email address of the recipient | string |
n/a | yes |
| kms_key_arn | The ARN of the KMS key used to encrypt and decrypt sensitive data | string |
"" |
no |
| filter_paths | A set of S3 object key prefixes to filter on. Only objects with keys that match at least one of these prefixes will trigger the Lambda function. | string |
[""] |
no |
| Name | Description |
|---|---|
| lambda_function_arn | ARN of the Lambda function |
| s3_bucket_name | Name of the S3 bucket |
| email_sender_role_arn | ARN of the IAM role for the Lambda function |
| email_sender_role_name | Name of the IAM role for the Lambda function |
