<h1>YAML Scripts<a class="headerlink" href="#yaml-scripts" title="Permalink to this headline">¶</a></h1>
|
|
<p>This page provides a basic overview of correct YAML syntax, which is how Ansible
|
|
playbooks (our configuration management language) are expressed.
|
|
You may also wish to read playbook examples and will quickly pick this up from those.</p>
|
|
<div class="section" id="yaml-basics">
|
|
<h2>YAML Basics<a class="headerlink" href="#yaml-basics" title="Permalink to this headline">¶</a></h2>
|
|
<p>For <cite>ansible</cite>, every YAML script must be a list at it’s root-most
|
|
element. Each item in the list is a dictionary. These dictionaries
|
|
represent all the options you can use to write a <cite>ansible</cite> script. In
|
|
addition, all YAML files (regardless of their association with
|
|
<cite>ansible</cite> or not) should start with <tt class="docutils literal"><span class="pre">---</span></tt>.</p>
|
|
<p>In YAML a list can be represented in two ways. In one way all members
|
|
of a list are lines beginning at the same indentation level starting
|
|
with a <tt class="docutils literal"><span class="pre">-</span></tt> character:</p>
|
|
<div class="highlight-python"><pre>---
|
|
# A list of tasty fruits
|
|
- Apple
|
|
- Orange
|
|
- Strawberry
|
|
- Mango</pre>
|
|
</div>
|
|
<p>In the second way a list is represented as comma separated elements
|
|
surrounded by square brackets. Newlines are permitted between
|
|
elements:</p>
|
|
<div class="highlight-python"><pre>---
|
|
# A list of tasty fruits
|
|
[apple, orange, banana, mango]</pre>
|
|
</div>
|
|
<p>A dictionary is represented in a simple <tt class="docutils literal"><span class="pre">key:</span></tt> and <tt class="docutils literal"><span class="pre">value</span></tt> form:</p>
|
|
<div class="highlight-python"><pre>---
|
|
# An employee record
|
|
name: John Eckersberg
|
|
job: Developer
|
|
skill: Elite</pre>
|
|
</div>
|
|
<p>Like lists, dictionaries can be represented in an abbreviated form:</p>
|
|
<div class="highlight-python"><pre>---
|
|
# An employee record
|
|
{name: John Eckersberg, job: Developer, skill: Elite}</pre>
|
|
</div>
|
|
<p id="truthiness">You can specify a boolean value (true/false) in several forms:</p>
|
|
<div class="highlight-python"><pre>---
|
|
knows_oop: True
|
|
likes_emacs: TRUE
|
|
uses_cvs: false</pre>
|
|
</div>
|
|
<p>Finally, you can combine these data structures:</p>
|
|
<div class="highlight-python"><pre>---
|
|
# An employee record
|
|
name: John Eckersberg
|
|
job: Developer
|
|
skill: Elite
|
|
employed: True
|
|
foods:
|
|
- Apple
|
|
- Orange
|
|
- Strawberry
|
|
- Mango
|
|
languages:
|
|
ruby: Elite
|
|
python: Elite
|
|
dotnet: Lame</pre>
|
|
</div>
|
|
