Steps to create the server with a Docker image

1. First I built a docker image with modified nginx.conf file, index.html and version.html file

2. Pushed that docker image to the docker hub

3. Then I created a modular terraform script that creates these resources below
-EC2 instance
-AWS Key pair - You will have to generate for yourself using ssh-keygen
-Security group
-VPC
-Internet gateway
-Route table and association
-Public subnet

4. The user data in EC2 is a file (entry-script) that installs docker and launches a docker container at port 80

5. Then using the server IP, I created an A record in route53 hosted zone for my website. www.harveensingh.com

6. An application load balancer can be set up by creating a target group and adding that EC2 instance to the group. ALB listener will be 80, protocol will be HTTP.

7. All the variables of this infrastructure can be controlled by changing values in terraform.tfvars file.
