# Polkadot Node
---
## Overview
This Terraform module simplifies the deployment of AWS EC2 instances and the configuration of Ansible, allowing you to automate infrastructure provisioning effortlessly.
---
## Features
- **AWS EC2 Instance Creation**: Easily create AWS EC2 instances to suit your workload requirements.
- **Ansible Configuration**: Configure Ansible on EC2 instances for efficient automation.
- **Customization**: Customize instance counts, types, and security groups to meet your infrastructure needs.
- **Ansible Playbooks**: Specify source and destination paths for Ansible playbooks.
---
## Usage
To use this Terraform module, include it in your Terraform configuration and specify the required variables. Here's an example:
```hcl
module "ec2_instances" {
source = "./ec2_instance"
instance_count = 2
instance_type = "m4.2xlarge"
instance_name = "polkadot-node"
security_group_name = "Allow access to instance"
key_name = "private_key"
ami_id = "ami-04e601abe3e1a910f" # Ubuntu
private_key_path = "/tmp/private_key.pem"
ansible_src_path = "ansible"
ansible_dst_path = "/home/ubuntu/ansible"
}
```
## How to run?
The easiest way is to use the Makefile commands:
```Makefile
# Create the resources
make apply_auto
# Destroy the resources
make destroy_auto
```
---
## Outputs
- **private_key_content**: The content of the private key.
- **public_ip_addresses**: The public IP addresses of the EC2 instances.

---
## TODOs
- [ ] Automatic Updates
- Generate the dynamic inventory with Terraform to allow Ansible access to the instances
- Keep the private keys, and use them from Ansible
- Update the `ansible/vars.yaml` the `polkadot.version` variable to the latest version.
- Run the Ansible command to update the binary to all the instances defined in the inventory.
- [ ] Update the user who runs the binary (non-root)
- [ ] Split the file system in different EBS (volumes), to have inmutable infrastructure.
