Structure of Automation

collections contain various modules and Ansible Roles that collectively (intentional use here) serve the end user and must (emphasis on this word) collectively work together, be tested together and be released together.

Ansible Training

By default, Ansible 1.3 and later will try to use native OpenSSH for remote communication when possible. This enables ControlPersist (a performance feature), Kerberos, and options in ~/.ssh/config such as Jump Host setup. However, when using Enterprise Linux 6 operating systems as the control machine (Red Hat Enterprise Linux and derivatives such as CentOS), the version of OpenSSH may be too old to support ControlPersist. On these operating systems, Ansible will fallback into using a high-quality Python implementation of OpenSSH called ‘paramiko’. If you wish to use features like Kerberized SSH and more, consider using Fedora, OS X, or Ubuntu as your control machine until a newer version of OpenSSH is available for your platform – or engage ‘accelerated mode’ in Ansible

The ansible can instantly send information across any distance, defying both time and space. Spanner isn’t the ansible. It can’t shrink space. But it works because those engineers found a way to harness time

How to generate Inventory Groups: The groups option can be used to pass a hash of group names and group members to be included in the generated inventory file.

You can also set ANSIBLE_VAULT_PASSWORD_FILE environment variable, e.g. ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass.txt and Ansible will automatically search for the password in that file.
