This repository contains two sub-projects for automating the provisioning and configuration of a cloud environment	1. **Terraform Project**	2. **Ansible Project**
	Automates the provisioning of cloud infrastructure using CSC's OpenStack `cPouta` service.	Configures and deploys a load balancer and web servers across the provisioned infrastructure.

Overview

This project demonstrates the complete lifecycle of deploying and configuring a cloud environment:

1. Provision Infrastructure: Use Terraform to create a cloud environment with:

   • A jumphost with public IP (VM1) serving as a load balancer.
   • Multiple private web servers (VM2, VM3, VM4) connected via a private network.

2. Configure Environment: Use Ansible to:

   • Install and configure Nginx on the jumphost as a load balancer.
   • Install and configure Nginx on web servers to serve static content.
   • Set up secure and consistent configurations across all VMs.

Getting Started

1. Terraform Setup

Step 1: Install Terraform

Follow the instructions in terraform/README.md to install and configure Terraform.

Step 2: Provision the Infrastructure

1. Navigate to the Terraform project directory:

   cd terraform/

2. Initialize Terraform:

   terraform init

3. Plan and apply the configuration:

   terraform apply

2. Ansible Configuration

Step 1: Install Ansible

Follow the instructions in ansible/README.md to install Ansible.

Step 2: Configure Load Balancer and Web Servers

1. Navigate to the Ansible project directory:

   cd ansible/

2. Test connectivity to all VMs:

   ansible -i inventory.ini -m ping all

3. Run the Ansible playbook:

   ansible-playbook -i inventory.ini webservers.yml

Expected Results

• Jumphost (VM1):

  • Acts as a load balancer using Nginx.
  • Forwards HTTP traffic to the web servers in a round-robin manner.

• Web Servers (VM2, VM3, VM4):

  • Serve the same static HTML content.
  • Are accessible only from the private network.

You can test the setup by accessing the public IP of the jumphost.

Troubleshooting

1. Terraform Issues:

   • Ensure your OpenStack credentials are correctly set in providers.tf.
   • Check for typos in the variables.tf file.

2. Ansible Issues:

   • Verify SSH access to all VMs.
   • Check that nginx is running on all servers.

3. Network Issues:

   • Ensure that security groups allow the necessary traffic:
     • Port 22 for SSH.
     • Port 80 for HTTP.

Refer to the individual README files for more detailed troubleshooting steps.
