Overview
EC2 instances can be created, updated and deleted. Instances also support provisioning.
Playground
Terraform Registry ec2-instance Module
Configuration
provider "aws" {
profile = "default"
region = "us-west-2"
}
resource "aws_instance" "terraform-experiment-01" {
ami = "ami-000000000000000"
instance_type = "t2.small"
subnet_id = "subnet-0000000000000000"
key_name = "my-keypair-01"
security_groups = ["sg-0000000000000000"]
associate_public_ip_address = false
iam_instance_profile = aws_iam_instance_profile.some-profile
tags = {
Name = "terraform-experiment-01"
}
}
Configuration Details
Public IP
If nothing is specified, the instance will get a public IP. To disable allocation of a public address specify:
resource "aws_instance" ... {
...
associate_public_ip_address = false
...
}
Note that even if associate_public_ip_address
is explicitly set to "true", if the associated subnet has a map_public_ip_on_launch
= true, a public IP will be associated anyway.
Multiple Instances
variable "instances" {
default = "2"
}
resource "aws_instance" "my-instance" {
count = "${var.instances}"
...
tags = {
Name = "my-instance-${count.index + 1}"
}
}
