Hello Guy’s!!

This Moday I attended a session on real industry use case by redhatter(Mr. Sreejith Anujan and Mr. Arun Eapen) under LinuxWorld Informatics Pvt. Ltd. and sharing the feedback for same.

First of all I would like to thanks Mr. Vimal Daga sir and Ms. Preeti Ma’am for arranging such a amazing session for all of us.

This session was about Real use case Autamation using Ansible:-

And Now lets talk about the session:-

What is automation?

Automation is the application of technology, programs, processes to achieve outcomes with minimal human input.

Automation involves a very broad range of technologies including robotics and expert systems, telemetry and communications, electro-optics, Cybersecurity, process measurement and control, sensors, wireless applications, systems integration, test measurement, and many, many more.

What is ANSIBLE ?

Ansible is a configuration management system written in Pythonusing a declarative markup language to describe configurations. It is used to automate software configuration and deployment.

What is Red Hat Ansible Tower ?

Ansible Tower is a web-based solution that makes Ansible even more easy to use for IT teams of all kinds. It’s designed to be the hub for all of your automation tasks.

Tower allows you to control access to who can access what, even allowing sharing of SSH credentials without someone being able to transfer those credentials. Inventory can be graphically managed or synced with a wide variety of cloud sources. It logs all of your jobs, integrates well with LDAP, and has an amazing browsable REST API. Command line tools are available for easy integration with Jenkins as well. Provisioning callbacks provide great support for auto scaling topologies.

Ansible tower is very useful in the case of failing Controller node By which all the automation code can lose.Ansible tower gives clustering feature by which same automation code kept on centralised storage and shared to all the tower.

And when we have a use case of executing more than one playbook one by one we can use ansible tower workflow by which one playbook gets executed on completion of previous one.

WorkFlow

By using ansible workflow we can decide if any playbooks fails to execute the which playbook to run next orwe can give permission to the flow by which after approving the same next playbook will run.

Also we learn to integrate latest chat app like slack to integrate with anisble tower by which all the team can get notification foe the project.

Also we learnt about when there is no credential option available for different technology like oracle cloud then how can we create ourself for the same and complete our project.

Thnaks!!!

🔰 Keep Learning !! Keep Sharing !! 🔰
