Ansible Playbooks offer a repeatable, reusable, simple configuration management and multi-machine deployment system, one that is well suited to deploying complex applications. If you need to execute a task with Ansible more than once, write a playbook and put it under source control.Ansible can be used to install software, automate daily tasks, provision infrastructure and network components, improve security and compliance, patch systems, and orchestrate complex workflows.
What is the usage Ansible playbook : Using Ansible playbooks
- Executing tasks with elevated privileges or as a different user.

Why Ansible is better than shell script
In most cases you can't just replay a shell script, because it will try to do a lot of things that are already done and it is very hard to write idempotent commands. Ansible on the other hand only performs the tasks in the playbook that need to be performed: if the condition is already satisfied, there's nothing to do.

What is the difference between Ansible play and playbook : Ansible Playbooks are lists of tasks that automatically execute for your specified inventory or groups of hosts. One or more Ansible tasks can be combined to make a play—an ordered grouping of tasks mapped to specific hosts—and tasks are executed in the order in which they are written.

At a basic level, a task is nothing more than a call to an ansible module.Docker containers offer a way to efficiently build an application, but they require a service to handle their configuration, deployment and orchestration. Ansible is useful for this — an Ansible playbook can install and configure Docker on the host machine, install a Docker image and run that image as a service.
