<p>Now to run the command on all servers in a group, in this case, ‘atlanta’:</p>
<divclass="highlight-python"><pre>ansible atlanta -a "/sbin/reboot" -f 10</pre>
</div>
<p>If you didn’t read about patterns and groups yet, go back and read <aclass="reference internal"href="patterns.html"><em>The Inventory File, Patterns, and Groups</em></a>.</p>
<p>If you want to run commands as a different user than root:</p>
<divclass="highlight-python"><pre>ansible atlanta -a "/usr/bin/foo" -u yourname</pre>
</div>
<p>If you want to run commands through sudo:</p>
<divclass="highlight-python"><pre>ansible atlanta -a "/usr/bin/foo" -u yourname --sudo</pre>
</div>
<p>If you need to access SSH on a different port:</p>
<divclass="highlight-python"><pre>ansible atlanta -a "/usr/bin/foo" -p 2112</pre>
</div>
<p>Ok, so those are basics. If you didn’t read about patterns and groups yet, go back and read <aclass="reference internal"href="patterns.html"><em>The Inventory File, Patterns, and Groups</em></a>.</p>
<p>The -f 10 in the above specifies the usage of 10 simultaneous processes. Normally commands also take
a <cite>-m</cite> for module name, but the default module name is ‘command’, so we didn’t need to specify that
here. We’ll use <cite>-m</cite> later to run some other <aclass="reference internal"href="modules.html"><em>Ansible Modules</em></a>.</p>

<p>We’ve learned well from “Infrastructure is Code”. Infrastructure should be easy and powerful to command, but it should not look like code, lest it acquire the disadvantages of a software project – bugs, complexity, and overhead. Infrastructure configurations should be simple, easy to develop, and easy to audit.</p>
