Terraform module which creates EC2 instance(s) on AWS.
These types of resources are supported:
Terraform 0.12. Pin module version to ~> v2.0. Submit pull-requests to master branch.
Terraform 0.11. Pin module version to ~> v1.0. Submit pull-requests to terraform011 branch.
module "ec2_cluster" {
source = "terraform-aws-modules/ec2-instance/aws"
version = "~> 2.0"
name = "my-cluster"
instance_count = 5
ami = "ami-ebd02392"
instance_type = "t2.micro"
key_name = "user1"
monitoring = true
vpc_security_group_ids = ["sg-12345678"]
subnet_id = "subnet-eddcdzz4"
tags = {
Terraform = "true"
Environment = "dev"
}
}This module does not support encrypted AMI's out of the box however it is easy enough for you to generate one for use
This example creates an encrypted image from the latest ubuntu 16.04 base image.
resource "aws_ami_copy" "ubuntu-xenial-encrypted-ami" {
name = "ubuntu-xenial-encrypted-ami"
description = "An encrypted root ami based off ${data.aws_ami.ubuntu-xenial.id}"
source_ami_id = "${data.aws_ami.ubuntu-xenial.id}"
source_ami_region = "eu-west-2"
encrypted = "true"
tags {
Name = "ubuntu-xenial-encrypted-ami"
}
}
data "aws_ami" "encrypted-ami" {
most_recent = true
filter {
name = "name"
values = ["ubuntu-xenial-encrypted"]
}
owners = ["self"]
}
data "aws_ami" "ubuntu-xenial" {
most_recent = true
filter {
name = "name"
values = ["ubuntu/images/hvm-ssd/ubuntu-xenial-16.04-amd64-server-*"]

}network_interfacecan't be specified together withassociate_public_ip_address, which makesnetwork_interfacenot configurable using this module at the moment- Changes in
ebs_block_deviceargument will be ignored. Use aws_volume_attachment resource to attach and detach volumes from AWS EC2 instances. See this example. - One of
subnet_idorsubnet_idsis required. If both are provided, the value ofsubnet_idis prepended to the value ofsubnet_ids.
