Terraform Module for providing N general purpose EC2 hosts.
If you only need to provision a single EC2 instance, consider using the [terraform-aws-ec2-instance](https://github.com/cloudposse/terraform-aws-ec2-instance) module instead.
**IMPORTANT** This module by-design does not provision an AutoScaling group. It was designed to provision a discrete number of instances suitable for running stateful services such as databases (e.g. Kafka, Redis, etc).
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`](https://atmos.tools) to easily orchestrate multiple environments using Terraform.
> Works with [Github Actions](https://atmos.tools/integrations/github-actions/), [Atlantis](https://atmos.tools/integrations/atlantis), or [Spacelift](https://atmos.tools/integrations/spacelift).
>
>
> Watch demo of using Atmos with Terraform
> 
> Example of running atmos to manage infrastructure from our Quick Start tutorial.

## 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:
```hcl
module "instance" {
source = "cloudposse/ec2-instance-group/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
namespace = "eg"
stage = "prod"
name = "app"
ami = "ami-a4dc46db"
ami_owner = "099720109477"
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
instance_count = 3
}
```
### Example with additional volumes and EIP
```hcl
module "kafka_instance" {
source = "cloudposse/ec2-instance-group/aws"
# Cloud Posse recommends pinning every module to a specific version
# version = "x.x.x"
namespace = "eg"
stage = "prod"
name = "app"
ami = "ami-a4dc46db"
ami_owner = "099720109477"
ssh_key_pair = var.ssh_key_pair
vpc_id = var.vpc_id
security_groups = var.security_groups
subnet = var.subnet
associate_public_ip_address = true
additional_ips_count = 1
ebs_volume_count = 2
instance_count = 3
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"]
}
]
}
```
### Additional complete working example with variations of how to use the module
In /examples directory
This module depends on these modules:
* [terraform-terraform-label](https://github.com/cloudposse/terraform-terraform-label)
It is necessary to run `terraform get` or `terraform init` to download this module.
Now reference the label when creating an instance (for example):
```hcl
resource "aws_ami_from_instance" "example" {
count = length(module.instance.*.id)
name = "app"
source_instance_id = element(module.instance.*.id, count.index)
}
```
> [!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.
