<h1>Using the Python API<a class="headerlink" href="#using-the-python-api" title="Permalink to this headline">¶</a></h1>
|
|
<p>The Python API is very powerful, and is how the ansible CLI and ansible-playbook
|
|
are implemented.</p>
|
|
<p>It’s pretty simple:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">ansible.runner</span>
|
|
|
|
<span class="n">runner</span> <span class="o">=</span> <span class="n">ansible</span><span class="o">.</span><span class="n">runner</span><span class="o">.</span><span class="n">Runner</span><span class="p">(</span>
|
|
<span class="n">module_name</span><span class="o">=</span><span class="s">'ping'</span><span class="p">,</span>
|
|
<span class="n">module_args</span><span class="o">=</span><span class="s">''</span><span class="p">,</span>
|
|
<span class="n">pattern</span><span class="o">=</span><span class="s">'web*'</span><span class="p">,</span>
|
|
<span class="n">forks</span><span class="o">=</span><span class="mi">10</span>
|
|
<span class="p">)</span>
|

<span class="n">datastructure</span> <span class="o">=</span> <span class="n">runner</span><span class="o">.</span><span class="n">run</span><span class="p">()</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>The run method returns results per host, grouped by whether they
|
|
could be contacted or not. Return types are module specific, as
|
|
expressed in the ‘ansible-modules’ documentation.:</p>
|
|
<div class="highlight-python"><pre>{
|
|
"dark" : {
|
|
"web1.example.com" : "failure message"
|
|
}
|
|
"contacted" : {
|
|
"web2.example.com" : 1
|
|
}
|
|
}</pre>
|
|
</div>
|
|
<p>A module can return any type of JSON data it wants, so Ansible can
|
|
be used as a framework to rapidly build powerful applications and scripts.</p>
