<p>Ansible works against multiple systems in your infrastructure at the
|
|
same time. It does this by selecting portions of systems listed in
|
|
Ansible’s inventory file, which defaults to /etc/ansible/hosts, and
|
|
looks like this:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="n">mail</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
|
|
|
|
<span class="p">[</span><span class="n">webservers</span><span class="p">]</span>
|
|
<span class="n">foo</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
|
|
<span class="n">bar</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
|
|
|
|
<span class="p">[</span><span class="n">dbservers</span><span class="p">]</span>
|
|
<span class="n">one</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
|
|
<span class="n">two</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
|
|
<span class="n">three</span><span class="o">.</span><span class="n">example</span><span class="o">.</span><span class="n">com</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>The things in brackets are group names, you don’t have to have them,
|
|
but they are useful.</p>
|
|
</div>
|
|
<div class="section" id="selecting-targets">
|
|
<h2>Selecting Targets<a class="headerlink" href="#selecting-targets" title="Permalink to this headline">¶</a></h2>
|
|
<p>These patterns target all hosts in the inventory file:</p>
|
|
<div class="highlight-python"><pre>all
|
|
*</pre>
|
|
</div>
|
|
<p>Basically ‘all’ is an alias for ‘*’. It is also possible to address a specific host or hosts:</p>
|
|
<div class="highlight-python"><pre>one.example.com
|
|
one.example.com:two.example.com
|
|
192.168.1.50
|
|
192.168.1.*</pre>
|
|
</div>
|
|
<p>The following patterns address one or more groups, which are denoted
|
|
with the aforementioned bracket headers in the inventory file:</p>
|
|
<div class="highlight-python"><pre>webservers
|
|
webservers:dbservers</pre>
|
|
</div>
|
|
<p>Individual host names (or IPs), but not groups, can also be referenced using
|
|
wildcards:</p>
|
|
<div class="highlight-python"><pre>*.example.com
|
|
*.com</pre>
|
|
</div>
|
|
<p>It’s also ok to mix wildcard patterns and groups at the same time:</p>
|
|
<div class="highlight-python"><pre>one*.com:dbservers</pre>
|
|
</div>
|
|
<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">It is not possible to target a host not in the inventory file. This is a safety feature.</p>
|
|
</div>
|
|
<p>Easy enough. Now see <a class="reference internal" href="examples.html"><em>Command Line Examples</em></a> and then <a class="reference internal" href="playbooks.html"><em>Playbooks</em></a> for how to do things to selected hosts.</p>
