Ansible DevOps Cookbook, Montgomery T.

   A collection of over seventy-five solution-focused recipes, "Ansible DevOps Cookbook" will show you how to use Ansible to fix problems, simplify operations, and boost the efficiency of your DevOps practices. Clear, step-by-step directions are provided for every recipe in this cookbook, covering everything from basic setup to advanced techniques.
You should start by creating an efficient inventory system, configuring control and managed nodes, and setting up your Ansible environment. You can implement effective solutions because the recipes address specific challenges. Get a handle on more complex playbook techniques, such as working with variables, facts, conditionals, loops, and more. You will be skillful to organize playbooks and create reusable automation with Ansible roles. You can increase your automation capabilities by accessing community-driven content through Ansible Galaxy, which is explained in the book.




Setting up SSH Key-based Authentication.
Authentication is quite a needy mechanism for managing remote machines securely, and there are several types of authentication methods available, including password-based, token-based, and key-based authentication. Password-based authentication requires you to enter a password each time you connect to a remote machine. While simple, it poses security risks such as susceptibility to brute-force attacks. Token-based authentication uses time-sensitive tokens and is commonly used in multi-factor authentication scenarios.

Key-based authentication, on the other hand, is considered more secure and efficient. It uses a pair of cryptographic keys: a public key stored on the remote machine and a private key stored securely on your control node. This method eliminates the need for password entry during connections, reduces the risk of brute-force attacks, and allows for automated, secure connections.
