The unofficial guide to becoming an EX407 Redhat certified specialist in Ansible automation
Ansible is set to be the standard in the world of IT infrastructure management. It’s a rare combination of simplicity meeting sophistication. Its core principle is simple is reflected in all its design choices such as an agentless setup, small footprint, push model, YAML as a language to define infrastructure state and so on. It’s easy to setup, easy to write code with, and easy to extend while writing custom modules. At the same time, it offers everything an IT system, networks or a operations/DevOps person needs. Once you set up the environment with the code spaces tool, you start diving into the simple and sophisticated world of Ansible one concept at a time. By the end of this course, you will have mastered Ansible and should be able to use it to automate servers, applications, and understand all the primitives that Ansible offers.
This course is been created to help you master Ansible one step at a time. It starts with the fundamental concepts related to infrastructure as code, what Ansible is, what is Idempotence, and what makes Ansible stand apart. Then it helps you relate Ansible to your project by taking up a use case.
What You Will Learn
- What is Ansible, why it’s needed and how it works?
- How to configure Ansible and setup static/dynamic inventories.
- Ad hoc server management, running jobs in parallel.
- Managing systems entities using Ansible modules.
- Writing playbooks to define the state of infrastructure as a code.
- Creating modular, reusable code with roles.
- Creating dynamic code with vars and templates.
- Using Ansible Galaxy.
- Encrypting sensitive data with Vault.
- Service discovery and managing multiple environments.
- Application deployment strategies, and rolling updates.
