Vanhack Test

This is a short example to attend the Vanhacktest requirements.

The code contains Ansible playbooks that will deploy in AWS the Infrastructure needed in order to Run

• EC2 Instance (s)
• RDS instance
• ELB classic

After the infrastructure is deployed, the Web application written in Python will be copied to previous EC2 Instances.

There are two options to execute.

• Pre-Loaded Environment
• Load environment from scratch

Pre-Loaded Environment:

URL: http://vanhack-load-balancer-1758030516.us-east-1.elb.amazonaws.com

Repository https://github.com/juanjopb/vanhacktest branch preloadenvironment

If you want to get into the EC2 instances (us-east-1 - N. Virginia) using ssh:

• You will need the PEM file that was sent by email or the PEM file that vanhack informed by the email.
• ssh -i "aws-private.pem" [email protected]
• ssh -i "aws-private.pem" [email protected]

Load From Scratch:

Note: The code was tested deploying from Ubuntu 19.04 machine, but should works using different distributions or SO. You could deploy this code using the AWS credentials sent or using different AWS account. but It necessary to have configured some credentials.

Requirements:

There are some requirements in order to run the code

• AWS credentials sent by email, or any AWS Account
• Python, Git, Ansible, Awscli installed.

$ sudo apt-get install python3.7 python-pip git awscli
$ pip install boto boto3 ansible

Before to deploy

Some configurations could be customized, the settings are located on AWS_Ansible/playbooks/group_vars/all To change names, regions to deploy, or amount of instances, please take a look at the mentioned file.

Note: Using the AWS Credentials sent and cloning the repository with the master branch will deploy a New version in the Region (us-east-2 Ohio) if you are going to deploy in another region, need to be changed the (base_image) ami and aws_region looking for a corresponding Image on the Region If you want to deploy more than one instance, please modify 'ec2_count_instances=desired number'

Deploying

1. Configure the aws credentials, `cd ~/.aws

$ cd ~/.aws
$ vim credentials
$ [default]
$ aws_access_key_id = Access_Key_Sent_by_email
$ aws_secret_access_key = Secret_Access_Key_Sent_by_email

2. Clone the repo https://github.com/juanjopb/vanhacktest

3. Located on the top of the cloned repo run the following command

$ vanhacktest > ansible-playbook -i AWS_Ansible/playbooks/inventory/hosts AWS_Ansible/playbooks/All-tasks.yml -e 'ansible_python_interpreter=/usr/bin/python3'

4. The deploy will start to show the progress

Note: The first time deploying the RDS instance could take almost 30 minutes to be ready. To avoid the time there is a RDS Instance preloaded.

Note: A private key will be saved on AWS_Ansible/aws-private.pem, please be careful and don't lose it, you will need to enter on the EC2 Instances..

5. Take note about the URL Endpoint Generated at the end of the Ansible Script.
