- Organize and write code with the help of Ansible playbooks and manage and automate your infrastructure seamlesslyKey FeaturesGet to grips with Ansible's features such as orchestration, automatic node discovery, and data encryptionCreate data-driven, modular and reusable automation code with Ansible roles, facts, variables, and templatesFollow a step-by-step approach to automating and managing system and application configurations effectively using Ansible's playbooksBook DescriptionAnsible Playbook Essentials will show you how to write a blueprint of your infrastructure, encompassing multitier applications using Ansible's playbooks. Beginning with basic concepts such as plays, tasks, handlers, inventory, and YAML Ain't Markup Language (YAML) syntax that Ansible uses, you'll understand how to organize your code into a modular structure. Building on this, you will study techniques to create data-driven playbooks with variables, templates, logical constructs, and encrypted data, which will further strengthen your application skills in Ansible. Adding to this, the book will also take you through advanced clustering concepts, such as discovering topology information about other nodes in the cluster and managing multiple environments with isolated configurations. As you approach the concluding chapters, you can expect to learn about orchestrating infrastructure and deploying applications in a coordinated manner.By the end of this book, you will be able to design solutions to your automation and orchestration problems using playbooks quickly and efficiently.What you will learnWrite simple tasks and playsOrganize code into a reusable, modular structureSeparate code from data using variables and Jinja2 templatesRun custom commands and scripts using Ansible's command modulesControl execution flow based on conditionalsIntegrate nodes and discover topology information about other nodes in the clusterEncrypt data with Ansible VaultCreate environments with isolated configurations to match the application development workflowOrchestrate infrastructure and deploy applications in a coordinated mannerWho this book is forIf you are a systems or an automation engineer who wants to automate common infrastructure tasks, deploy applications, and use orchestration to configure systems in a synchronized manner, this book is ideal for you.
