+
+## Requirements
+- AWS Account 
+- Terraform
+- AWS CLI
+- Linux CLI 
+
+## How does it work?
+Basically, the Terraform will create some resources on AWS, such as, EC2, SG and the Ansible will be invoked via Terraform resources (local-exec) to call Ansible Roles for then to install the Docker app on EC2 instance.
+
+## Setup AWS credentials
+Use the AWS Documentation to setup your AWS Credentials, basically you have some ways to do this, for example via credentials file or environment variables:
+
+- In my case I used the ```~/.aws/credentials``` file to create my credentials:
+
+```
+[default]
+aws_access_key_id=AKIAIOSFODNN7EXAMPLE
+aws_secret_access_key=wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
+```
+
+## Create a AWS Key pairs
+Now you can create your Key pairs on AWS following the AWS Documentation below:
+
+- [Create AWS Key pairs](https://docs.aws.amazon.com/pt_br/AWSEC2/latest/UserGuide/ec2-key-pairs.html)
+
+Remember you can create a Terraform resource to provision automatically:
+
+```
+resource "aws_key_pair" "deployer" {
+  key_name   = "deployer-key"
+  public_key = "ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3F6tyPEFEzV0LX3X8BsXdMsQz1x2cEikKDEY0aIj41qgxMCP/iteneqXSIFZBp5vizPvaoIR3Um9xK7PGoW8giupGn+EPuxIA4cDM4vzOqOkiMPhz5XK0whEjkVzTo4+S0puvDZuwIsdiW9mxhJc7tgBNL0cYlWSYVkz4G/fslNfRPW5mYAM49f4fhtxPb5ok4Q2Lg9dPKVHO/Bgeu5woMc7RY0p1ej6D4CKFE6lymSDJpW0YHX/wqE9+cfEauh7xZcG0q9t2ta6F6fmX0agvpFyZo8aFbXeUBr7osSCJNgvavWbM/06niWrOvYX2xwWdhXmXSrbX8ZbabVohBK41 [email protected]"
+}
+```
+
+## Create the Terraform files
+According to the best practices from the Terraform documentation, is necessary create several files ".tf" to keep the environment working fine, the Terraform will read all files ".tf" and will provision on the AWS Cloud.
+
+- provider.tf
+- securityGroups.tf
+- ec2Intance.tf
+
+## Terraform CLI Usage
+Main commands:
+
+```
+  init          Prepare your working directory for other commands
+  validate      Check whether the configuration is valid
+  plan          Show changes required by the current configuration
+  apply         Create or update infrastructure
+  destroy       Destroy previously-created infrastructure
+```
+
+Execute these commands after get completed before steps:
+
+```
+$ terraform init
+$ terraform plan
+$ terraform apply
+$ terraform destroy
+```
