Confirming the Required Directory Structure

Before proceeding, change to the light-app directory. It is important to be in this directory when running the ansible-playbook in the next section. Ansible depends on some files and directories to be in certain places.

$ cd ~/light-app

Run ls and make sure you see the following files and folders.

ansible

ansible.cfg

playbooks

plugins

roles

Additionally confirm the structure of your ansible directory to be similar to this:

$ tree ansible

ansible

└── inventories

    └── cluster_example

        ├── group_vars

        │   └── all.yml

        ├── host_vars

        │   ├── client_0.yml

        │   ├── server00.yml

        │   ├── server01.yml

        │   └── server02.yml

        └── hosts
