HashiCorp Terraform Supports Amazon Linux 2

HashiCorp Terraform Supports Amazon Linux 2

Jun 27 2018    Burzin Patel

Yesterday, AWS announced general availability of the new version of the Amazon Linux operating system, Amazon Linux 2. Amazon Linux 2 was built to provide organizations with an operating systems that leverages the latest Linux tools to build, test, and run cloud applications in both pre and post-production environments. It is available as an Amazon Machine Image (AMI) for Elastic Compute Cloud instances (EC2), as a container image for Docker, and as a virtual image for VMware, Oracle VM VirtualBox, and Microsoft Hyper-V. HashiCorp Terraform offers support for Amazon Linux 2 as a resource within a Terraform configuration. This blog explains how to use Terraform to provision new EC2 instances running Amazon Linux 2.

» Configuring an EC2 Instance with an Amazon Linux 2 AMI

Terraform supports Amazon Linux 2 as a resource when provisioning or managing EC2 instances on AWS. In order to create EC2 instances that runs on Amazon Linux 2, operators simply specify the AMI and data source. Here is a sample configuration of a Amazon Linux 2 instance resource:

data "aws_ami" "amazon-linux-2" {
 most_recent = true


 filter {
   name   = "owner-alias"
   values = ["amazon"]
 }


 filter {
   name   = "name"
   values = ["amzn2-ami-hvm*"]
 }
}


resource "aws_instance" "test" {
 depends_on = ["aws_internet_gateway.test"]


 ami                         = "${data.aws_ami.amazon-linux-2.id}"
 associate_public_ip_address = true
 iam_instance_profile        = "${aws_iam_instance_profile.test.id}"
 instance_type               = "t2.micro"
 key_name                    = "bflad-20180605"
 vpc_security_group_ids      = ["${aws_security_group.test.id}"]
 subnet_id                   = "${aws_subnet.test.id}"

As shown in this example, operators declare that this instance will run on an Amazon Linux 2 AMI and Terraform creates it once a terraform apply is run without any additional configurations.
