Terraform Module for provisioning a general purpose EC2 host.

Included features:

Automatically create a Security Group
Option to switch EIP attachment
CloudWatch monitoring and automatic reboot if instance hangs
Assume Role capability

[!TIP]

👽 Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform. Works with Github Actions, Atlantis, or Spacelift.
<details> <summary>Watch demo of using Atmos with Terraform</summary> <img src="https://github.com/cloudposse/atmos/blob/master/docs/demo.gif?raw=true"/> Example of running <a href="https://atmos.tools"><code>atmos</code></a> to manage infrastructure from our <a href="https://atmos.tools/quick-start/">Quick Start</a> tutorial. </detalis>

Usage

Note: add ${var.ssh_key_pair} private key to the ssh agent.

Include this repository as a module in your existing terraform code.

Simple example:

module "instance" {
  source = "cloudposse/ec2-instance/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"
  ssh_key_pair                = var.ssh_key_pair
  instance_type               = var.instance_type
  vpc_id                      = var.vpc_id
  security_groups             = var.security_groups
  subnet                      = var.subnet
  name                        = "ec2"
  namespace                   = "eg"
  stage                       = "dev"
}

Example with additional volumes and EIP

  source = "cloudposse/ec2-instance/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"

  namespace                   = "eg"
  stage                       = "dev"
  additional_ips_count        = 1
  ebs_volume_count            = 2
  security_group_rules = [
    {
      type        = "egress"
      from_port   = 0
      to_port     = 65535
      protocol    = "-1"
      cidr_blocks = ["0.0.0.0/0"]
    },
    {
      type        = "ingress"
      from_port   = 22
      to_port     = 22
      protocol    = "tcp"
      cidr_blocks = ["0.0.0.0/0"]
    },
    {
      type        = "ingress"
      from_port   = 80
      to_port     = 80
      protocol    = "tcp"
      cidr_blocks = ["0.0.0.0/0"]
    },
    {
      type        = "ingress"
      from_port   = 443
      to_port     = 443
      protocol    = "tcp"
      cidr_blocks = ["0.0.0.0/0"]
    },
    {
      type        = "ingress"
      from_port   = 53
      to_port     = 53
      protocol    = "udp"
      cidr_blocks = ["0.0.0.0/0"]
    },
  ]
}

[!IMPORTANT] In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.
