Overview

EC2 instances can be created, updated and deleted. Instances also support provisioning.

Configuration

provider "aws" {

  profile = "default"
  region = "us-west-2"
}

resource "aws_instance" "terraform-test-01" {

  ami           = "ami-a6faba49dddaecfb7"
  instance_type = "m5.4xlarge"
}

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.
