Description

In this project, we have 4 role which are responsible for configure our system madular.

1. role postgres : for installing and configuring postgres database server.
2. role nginx : for installing and configuring nginx webserver and deploying the code.
3. role common : for configuring common requirment of servers.
4. role learning : for learning purpose, I wanted to test variable priority and test loops in ansible.

On learning role I found that variable priority is like :

1. 1. group_vars
2. 2. vars
3. 3. default

1.An ansible playbook for executing the configs

#ansible-playbook site.yml -i inventory/sample/hosts.yml
