Ansible Meaning

Ansible provides powerful Automating cloud provisioning, continuous deployments and zero-downtime rolling upgrades – as well as IT orchestration features that enhance its power.

Ansible sends tasks to clients using Python as its language of communication, these could include virtual servers or physical ones in cloud environments.

Small Python programs known as Ansible Modules run Ansible on client machines before being executed by them for execution on Ansible’s behalf by Ansible itself.

Ansible server then sends module output from client system back into playbook through Ansible-ssh to orchestrate chores in sequence without using servers as orchestrators.

Key features of Ansible include:

API: Ansible’s API allows easy integration and extension.

Modular Structure: Using one file that stores all jobs for easier management.

Push Architecture: Receiving all modules via client requests before sending their output back out again for control by another machine.

Ansible Playbooks or Playbook Ansible

Ansible playbooks enable IT teams to effectively automate cloud infrastructure, virtualization and other IT tools with ease.

Ansible Playbooks contain human-readable YAML files listing tasks to be carried out using Ansible Automation Engine on either a control system or managed remote machine, using Ansible-playbook as a platform.

Ansible playbooks offer many advantages; just some include:

Easy to write: Python developers can write playbooks quickly and effortlessly similar to writing Python scripts.  when writing playbooks using YAML playbooks; their playbooks can list and execute tasks just like regular Python code does.

Easy to read: Their YAML format makes reading playbooks human-friendly so even people without programming experience can understand its contents.

Easy to Debug: Even minor changes made while debugging playbooks won’t affect execution; thus, making finding issues much simpler.

Highly Portable: Playbooks in ansible are Linux compatible and highly portable!

Playbooks in Ansible

Ansible Playbooks provide tasks for configuring and managing machines using Ansible’s YAML language format, making them highly capable at automating multiple tasks.

Ansible playbooks serve as files listing remote tasks to be performed; each task written down as human-readable YAML allowing clear documentation.

Steps to Create Ansible Playbooks:

Deploy Application Playbook: Used to deploy apps onto servers. It involves creating folders, environment variables, user accounts and program settings before starting installation of apps on them.

Create Database Playbook: Generating server databases along with users, permissions and database names and configuration.

Install Packages Playbook: Install server packages by installing, downloading and verifying their checksums.

Configure Services Playbook: Set Up Services This playbook focuses on configuring server services like service accounts, log rotation and firewalling – such as service accounts log rotation or firewalling.
