What is Ansible?


✓ -:- Open source automation platform providing language that allows to describe in

a declarative fashion a desired state of IT application infrastructure.




Ansible Playbooks are written in...


✓ -:- YAML




Ansible traits


✓ -:- 1. Agentless - target systems do not need any agent software. Ansible most

often connects to target systems via SSH/WinRM and injects small programs called

"ansible modules" that put the system in the desired state, described in the

playbook.




2. Cross-platform




3. Human-readable

Ansible Node Types


✓ -:- 1. Control node - Ansible is installed there and it stores playbooks, inventories

etc.




2. Managed hosts - Those are listed in inventories. Hosts which control node connects and

makes changes to put them in the desired state, defined by a playbook.




What does it mean that Ansible is indempotent?


✓ -:- You can safely run a playbook on the same hosts multiple times. When your

systems are in the correct state, the playbook makes no changes when you run it.

Not every module adheres to that out of the box.




How to register new RHEL for subscription?


✓ -:- Usually two commands are used to do that:




1. subscription-manager register --username=youruser --password=yourpwd


2. subscription-manager --attach --pool=poolID




Where pools and their IDs can be viewed by:

subscription-manager list --available




How to enable a new RHEL software repository with CMDs?


✓ -:- To add repo:




subscription-manager repos --enable "repo_name"




To list repo:




subscription-manager repos --list




What are the requirements for using Ansible on RHEL8?


✓ -:- 1. Python (at least 3.5 or 2.7) - can be "platform-python" pkg

2. "ansible-core" package installed on control node


3. Python in the same minimal version should be present on managed nodes (if SELinux is

present, install "python3-libselinux" too)




To check:


- ansible --version

- ansible -m setup localhost | grep python_version




What is Ansible Inventory? And what types are there.


✓ -:- Collection of hosts that Ansible will manage. Those hosts can be assigned to

groups that are collectively managed. Those groups can have child groups and hosts

can be in multiple groups.




Default Ansible inventory resides in /etc/ansible/hosts




Inventory can be:


1. Static - defined in a INI or YAML text file


2. Dynamic - generated by a script or program as needed




Groups in Ansible Inventory


✓ -:- Inventory always has 2 default groups:

1. all - every host mentioned in the inventory


2. ungrouped - every host mentioned in the inventory that is not a member of any other

group
