Ansible For Linux by Examples (The Course)
Course Info
This course includes 1 attempt.
Ansible is an Open Source IT automation tool. This book contains all of the obvious and not-so-obvious best practices of Ansible automation. Every successful IT department needs automation nowadays for bare metal servers, virtual machines, could, containers, and edge computing. Automate your IT journey with Ansible automation technology.
You are going to start with the installation of Ansible in Enterprise and Community Linux using the most command package manager and archives.
Each of the 100+ lessons summarizes a module: from the most important parameter to some Ansible code and real-life usage. Each code is battle proved in the real life. Simplifying mundane activities like creating a text file, extracting and archiving, and fetching a repository using HTTPS or SSH connections could be automated with some lines of code and these are only some of the long lists included in the course.
There are some Ansible codes usable in all the Linux systems, some specific for RedHat-like, Debian-like, and Suse-like.
The 20+ Ansible troubleshooting lesson teaches you how to read the error message, how to reproduce it, and the process of troubleshooting and resolution.
Are you ready to automate your day with Ansible?
Examples in the book are tested with the latest version of Ansible 2.9+ and Ansible Core 2.11+.
