AWS Cluster Setup with Terraform and Ansible

This project leverages Terraform and Ansible to automate the creation of a cluster on AWS. With a single command, you can set up a cluster of your desired size. This solution is ideal for those who want to quickly provision AWS infrastructure and manage it with automation tools.

Features

• Automated Cluster Setup: Create a cluster on AWS with any number of worker nodes.
• Easy to Use: Simply run make and provide the number of nodes when prompted.
• Customizable: Modify configuration files to adjust your environment.

Prerequisites

Before you begin, ensure you have the following tools installed:

• Terraform (v1.x or higher)
• Ansible (v2.x or higher)
• AWS CLI (configured with your AWS credentials)

Getting Started

1. Clone the repository: Clone this repository to your local machine.

   git clone https://github.com/yourusername/your-repository.git
   cd your-repository

2. Configure the values: You need to adjust some default values based on your environment before running the setup.

   • Edit the worker and master node setup variables:

     • maker-cluster/ansible/setup-worker-node/vars/main.yml
     • maker-cluster/ansible/setup-master-node/vars/main.yml

   • Set the desired AWS region in the Terraform configuration.

     • maker-cluster/terraform/main.tf

   In these files, you can change settings like instance types, region, or any other parameters according to your requirements.

3. Run the setup: To create the cluster, simply run the following command:

   make

   You will be prompted to enter the number of worker nodes you want to create. Once provided, the Terraform and Ansible scripts will automatically deploy the infrastructure and configure your cluster.

Configuration Files

maker-cluster/ansible/setup-worker-node/vars/main.yml

This file contains hosts where to find the key locally:

• key location

maker-cluster/ansible/setup-master-node/vars/main.yml

This file contains the configuration for the Master created key location for local computer:

• key location

Region Configuration

The region for the AWS infrastructure can be configured in the Terraform files or as an environment variable:

• In maker-cluster/terraform/main.tf, set the desired AWS region.

  provider "aws" {
    region = "us-west-2" # Update this to your desired region
  }

Cleanup

Once you’re done with the cluster, you can easily destroy all resources by running:

make stop

This will destroy the AWS infrastructure created by Terraform, ensuring no resources are left behind.
