Project - Deploy simple web application on AWS

Overview

In this project, I'm trying to automate the process of deploying a simple web application on AWS:

Terraform - As an infrastructure provisioning tool to automate the infrastructure provisioning process
Ansible - As a configuration management tool to configure the web application server after provisioning

My process

I've used Terraform to isolate the application to its environment by creating its own VPC, subnet, route tables, security groups, and key pair. After setting up the environment and creating the EC2 instance, I handed over the configuration part of the server to a simple ansible playbook script in the ansible directory.

How to use the code

To use this code to provision this web application, you need the following:

AWS account with free tier
Install AWS CLI and configure it with your AWS access and secret keys
```
  aws configure
```

Create a terraform.tfvars file in the repo working directory with your preferred variables as below:

  webapp_azs = [ "eu-west-3a" ]
  webapp_public_subnets = [ "192.168.0.0/20" ]
  webapp_public_subnets_names = [ "webapp-public-subnet-1" ]
  webapp_vpc_cidr = "192.168.0.0/16"
  webapp_vpc_name = "webapp-vpc"
  webapp_igw_name = "webapp-igw"
  webapp_security_group_name = "webapp-sg"
  webapp_instance_type = "t2.micro"

Execute the below commands to initialize the terraform environment and apply the scripts.
```
  terraform init
  terraform apply --auto-approve
```

The output

After executing the Terraform script, you will get the public ip of the provisioned ec2 instance on the output section and you will get the private key .pem file in the repo working directory to use it for ssh remote login.
