AWS EC2 Instance Terraform module
Terraform module which creates an EC2 instance on AWS.
Usage
Single EC2 Instance
module "ec2_instance" {
source = "terraform-aws-modules/ec2-instance/aws"
name = "single-instance"
instance_type = "t2.micro"
key_name = "user1"
monitoring = true
vpc_security_group_ids = ["sg-12345678"]
subnet_id = "subnet-eddcdzz4"
tags = {
Terraform = "true"
Environment = "dev"
}
}
Multiple EC2 Instance
module "ec2_instance" {
source = "terraform-aws-modules/ec2-instance/aws"
for_each = toset(["one", "two", "three"])
name = "instance-${each.key}"
instance_type = "t2.micro"
key_name = "user1"
monitoring = true
vpc_security_group_ids = ["sg-12345678"]
subnet_id = "subnet-eddcdzz4"
tags = {
Terraform = "true"
Environment = "dev"
}
}
Spot EC2 Instance
module "ec2_instance" {
source = "terraform-aws-modules/ec2-instance/aws"
name = "spot-instance"
create_spot_instance = true
spot_price = "0.60"
spot_type = "persistent"
instance_type = "t2.micro"
key_name = "user1"
monitoring = true
vpc_security_group_ids = ["sg-12345678"]
subnet_id = "subnet-eddcdzz4"
tags = {
Terraform = "true"
Environment = "dev"
}
}
Module wrappers
Users of this Terraform module can create multiple similar resources by using for_each
meta-argument within module
block which became available in Terraform 0.13.
Users of Terragrunt can achieve similar results by using modules provided in the wrappers directory, if they prefer to reduce amount of configuration files.
Examples
- Complete EC2 instance
- EC2 instance w/ private network access via Session Manager
- EC2 instance with EBS volume attachment
Make an encrypted AMI for use
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.
provider "aws" {
region = "us-west-2"
}
data "aws_ami" "ubuntu" {
most_recent = true
owners = ["679593333241"]
filter {
name = "name"
values = ["ubuntu-minimal/images/hvm-ssd/ubuntu-focal-20.04-*"]
}
filter {
name = "virtualization-type"
values = ["hvm"]
}
}
resource "aws_ami_copy" "ubuntu_encrypted_ami" {
name = "ubuntu-encrypted-ami"
description = "An encrypted root ami based off ${data.aws_ami.ubuntu.id}"
source_ami_id = data.aws_ami.ubuntu.id
source_ami_region = "eu-west-2"
encrypted = true
tags = { Name = "ubuntu-encrypted-ami" }
}
data "aws_ami" "encrypted-ami" {
most_recent = true
filter {
name = "name"
values = [aws_ami_copy.ubuntu_encrypted_ami.id]
}
owners = ["self"]
}
Conditional creation
The following combinations are supported to conditionally create resources:
- Disable resource creation (no resources created):
create = false
- Create spot instance:
create_spot_instance = true
Notes
network_interface
can't be specified together withvpc_security_group_ids
,associate_public_ip_address
,subnet_id
. See complete example for details.- Changes in
ebs_block_device
argument will be ignored. Use aws_volume_attachment resource to attach and detach volumes from AWS EC2 instances. See this example. - In regards to spot instances, you must grant the
AWSServiceRoleForEC2Spot
service-linked role access to any custom KMS keys, otherwise your spot request and instances will fail withbad parameters
. You can see more details about why the request failed by using the awscli andaws ec2 describe-spot-instance-requests
