Terraform module to easily generate AMI snapshots to create replica instances
Tip
Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.
Watch demo of using Atmos with Terraform
Example of running
atmos to manage infrastructure from our Quick Start tutorial.
resource "aws_instance" "default" {
ami = "ami-408c7f28"
instance_type = "t1.micro"
tags = {
Name = "test1"
}
}
module "tf_ami_from_instance" {
source = "git::https://github.com/cloudposse/tf_ami_from_instance.git?ref=master"
source_instance_id = "${aws_instance.web.id}"
stage = "${var.stage}"
namespace = "${var.namespace}"
name = "${var.name}"
attributes = "${var.attributes}"
tags = "${var.tags}"
}
- Terraform will only keep the latest AMI snapshot (terraform will delete the previously generated AMI) See our Lamda based solution which avoids this pitfall: https://github.com/cloudposse/tf_lambda_ami_backup
- This is is not compatible with autoscaling groups
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.
