Ansible Playbook Essentials

Design automation blueprints using Ansible's playbooks to orchestrate and manage your multitier infrastructure About This BookGet 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 templatesA step-by-step approach to automating and managing system and application configurations effectively using Ansible's playbooksWho This Book Is ForIf you are a systems or automation engineer who intends to automate common infrastructure tasks, deploy applications, and use orchestration to configure systems in a coordinated manner, then this book is for you. Some understanding of the Linux/Unix command-line interface is expected.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 mannerIn DetailThis book 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 the YAML syntax that Ansible uses, you will see how to organize your code into a modular structure. Building on this, you will master techniques to create data-driven playbooks with variables, templates, logical constructs, and encrypted data. This book will also take you through advanced clustering concepts, such as discovering topology information about other nodes in the cluster, managing multiple environments with isolated configurations, and orchestrate infrastructure and deploy 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.
