Awesome

This repo contains a terraform module that creates two lambda functions that will create AMI automatically at regular intervals. It is based on the code at https://serverlesscode.com/post/lambda-schedule-ebs-snapshot-backups/ and https://serverlesscode.com/post/lambda-schedule-ebs-snapshot-backups-2/.

[!TIP]

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform. Works with Github Actions, Atlantis, or Spacelift.
<details> <summary>Watch demo of using Atmos with Terraform</summary> <img src="https://github.com/cloudposse/atmos/blob/master/docs/demo.gif?raw=true"/> Example of running <a href="https://atmos.tools"><code>atmos</code></a> to manage infrastructure from our <a href="https://atmos.tools/quick-start/">Quick Start</a> tutorial. </detalis>

Usage

Include this repository as a module in your existing terraform code:

module "lambda_ami_backup" {
  source = "git::https://github.com/cloudposse/terraform-aws-ec2-ami-backup.git?ref=tags/0.3.2"

  name           = "${var.name}"
  stage          = "${var.stage}"
  namespace      = "${var.namespace}"
  region         = "${var.region}"
  ami_owner      = "${var.ami_owner}"
  instance_id    = "${var.instance_id}"
  retention_days = "14"
}

[!IMPORTANT] In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Examples

Example on excluding some of attached EBS volumes:

module "lambda_ami_backup" {
  source = "git::https://github.com/cloudposse/terraform-aws-ec2-ami-backup.git?ref=tags/0.3.2"

  name           = "${var.name}"
  stage          = "${var.stage}"
  namespace      = "${var.namespace}"
  region         = "${var.region}"
  ami_owner      = "${var.ami_owner}"
  instance_id    = "${var.instance_id}"
  retention_days = "14"

  block_device_mappings = [
    { "DeviceName" = "/dev/xvdf", "NoDevice" = "" },
    { "DeviceName" = "/dev/xvdg", "NoDevice" = "" },
  ]
}
