Ansible Documentation
|
|
`````````````````````
|
|
|
|
Welcome to the Ansible documentation.
|
|
|
|
Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT orchestration
|
|
such as continuous deployments or zero downtime rolling updates.
|
|
|
|
Ansibe's goals are foremost those of simplicity and ease of use. It also has a strong focus on security and reliability, featuring
|
|
a minimum of moving parts, usage of Open SSH for transport, and a language that is designed around auditability by humans -- even those
|
|
not familiar with the program.
|
|
|
|
This documentation covers the current released version of Ansible (1.3.X) and also some development version features (1.4). For recent features, in each section, the version of Ansible where the feature is added is indicated. Ansible produces a new major release approximately
|
|
every 2 months.
|
|
|
|
Before we dive into playbooks, configuration management, deployment, and orchestration, we'll learn how to get Ansible installed and some
|
|
basic information. We'll go over how to execute ad-hoc commands in parallel across your nodes using /usr/bin/ansible. We'll also see
|
|
what sort of modules are available in Ansible's core (though you can also write your own, which we'll also show later).

An Introduction to Playbooks
|
|
````````````````````````````
|
|
|
|
Playbooks are Ansible's configuration, deployment, and orchestration language. They can describe a policy you want your remote systems
|
|
to enforce, or a set of steps in a general IT process.
|
|
|
|
At a basic level, playbooks can be used to manage configurations of and deployments to remote machines. At a more advanced level, they can sequence multi-tier rollouts involving rolling updates, and can delegate actions to other hosts, interacting with monitoring servers and load balancers along the way.
|
|
|
|
There's no need to learn everything at once. You can start small and pick up more features
|
|
over time as you need them.
|
|
|
|
Playbooks are designed to be human-readable and are developed in a basic text language. There are multiple
|
|
ways to organize playbooks and the files they include, and we'll offer up some suggestions on that and making the most out of Ansible.

Special Topics In Playbooks

|
|
|
|
Here are some playbook features that not everyone may need to learn, but can be quite useful for particular applications.
|
|
Browsing these topics is recommended as you may find some useful tips here, but feel free to learn Ansible first and adopt
|
|
these only if they seem relevant or useful to your environment::

playbooks_acceleration

playbooks_check_mode

Detailed Guides
|
|
```````````````
|
|
|
|
This section is new and evolving. The idea here is explore particular use cases in greater depth and provide a more "top down" explanation
|
|
of some basic features.
|
