Ansible terminology - What is an Ansible Playbook? — Video Tutorial

What is an Ansible Playbook? I will show you a live Playbook with some simple Ansible code. I'm Luca Berton, and welcome to today's episode of Ansible Pilot. Ansible Playbook - blueprint for automation - YAML format - Ansible language The Ansible Playbook is the blueprint for your automation. The Ansible Playbook enables you to execute any, again again, operation in a specified order. It's like a recipe book for someone who likes to cook a cake. Every ingredient needs to be added in a specific order at a particular moment of the execution. The code is human-readable in YAML format, a well-known easy-to-read coding format. Every line of coding is the Ansible language that is changed a little bit yearly, but the principles are always the same. Like all programming languages, you can declare variables, include other files, execute actions on conditions, and repeat with loops. Other particular actions, called handlers, execute only when another task is performed. You can execute your Ansible Playbook using the `ansible-playbook` command line utility included in any ansible installation. When the execution is successful, you obtain a green result, otherwise a failure with a relative error.
