Prerequisites

• Ansible
• Virtual Machines (VirtualBox or Cloud Providers)

How to implement

• Clone the repository
• Update the following variables in group_vars/all.yml:
  • db_user
  • db_user_password
  • gmail_password
  • gmail_username
  • to_email

Note: these values need to be encrypted using Ansible vault. You will need to encrypt each value one by one. To encrypt follow the steps below:

ansible-vault encrypt_string 'VALUE' --name 'db_user'

The value for the name parameter is the actual variable name you can reference in the playbook.

• After encryption paste the output of each encryption in the group_vars/all.yml. The value should be similar to

gmail_username:  !vault  |
$ANSIBLE_VAULT;1.1;AES256
61343235653635366234326237343638653563306239313161393361623564616666366532363833

• You will also need to add a variable which specifies your database name db_name. I haven't encrypted the value as it is not sensitive.
• If you are using cloud provider you can download a dynamic inventory script which can easily bring all your resources and not require you to define them manually using an inventory file. More about that here
• You can also manually specify the inventory file which is under playbooks/inventory/inventory.txt. You will need to update ansible_host, ansible_ssh_private_key_file and ansible_user. If you are using password based authentication on your virtual machine you can replace ansible_ssh_private_key_file for ansible_ssh_pass.
• In playbooks/main.yml update the hosts accordingly to the type of inventory you use.
• Once all values are updated execute make web or make simple_web based on what kind of inventory you use.
