Description

AWS released in May 2024 the capability to protect AMIs against mistaken Deregistrations.

• https://aws.amazon.com/about-aws/whats-new/2024/05/amazon-ec2-protects-amis-accidental-deregistration/
• https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/deregister-ami.html#ami-deregistration-protection

It would be nice to take this feature into account in order to streamline the setup of this additional layer of protection at AMI build time through Packer.

Use Case(s)

Some use cases could be:

• Prevention against mistaken AMI deregistration,
• legal locks for compliance, ...

Potential configuration

source "amazon-ebs" "basic-example" {
  source_ami_filter {
    filters = {
       virtualization-type = "hvm"
       name = "ubuntu/images/*ubuntu-xenial-16.04-amd64-server-*"
       root-device-type = "ebs"
    }
    owners = ["099720109477"]
    most_recent = true
    deregistration_protection {
      enabled = true
      cooldown_period = "24h"
    }
  }
}
