<h1>Introducing Ansible<a class="headerlink" href="#introducing-ansible" title="Permalink to this headline">¶</a></h1>
|
|
<p>Ansible is a radically simple deployment, configuration, and command
|
|
execution framework. Other similar tools have been too
|
|
complicated for too long, require too much bootstrapping, and have too
|
|
much learning curve. Ansible is dead simple and painless to extend.
|
|
For comparison, Puppet and Chef have about 60k lines of code.
|
|
Ansible’s core is a little over 1000 lines.</p>
|
|
<p>Ansible isn’t just for configuration – it’s also great for Ad-Hoc
|
|
tasks, quickly firing off commands against nodes. See <a class="reference internal" href="examples.html"><em>Command Line Examples</em></a>.
|
|
Where Ansible excels though, is expressing complex multi-node
|
|
deployment processes, executing complex sequences of commands on
|
|
different hosts through <a class="reference internal" href="playbooks.html"><em>Playbooks</em></a>.</p>
|
|
<p>Extending ansible does not require programming in any particular
|
|
language – you can write <a class="reference internal" href="modules.html"><em>Ansible Modules</em></a> as scripts or programs that return
|
|
simple JSON. It’s also trivially easy to just execute useful shell
|
|
commands.</p>
|
|
<p>Why use Ansible versus something else? (Puppet, Chef, Fabric,
|
|
Capistrano, mCollective, Func, SaltStack, etc?) Ansible will have far
|
|
less code, it will be (by extension) more correct, and it will be the
|
|
easiest thing to hack on and use you’ll ever see – regardless of your
|
|
favorite language of choice.</p>
|
|
<p>Systems management doesn’t have to be complicated. Ansible’s docs
|
|
will remain short & simple, and the source will be blindingly obvious.</p>

<h2>About the Author<a class="headerlink" href="#about-the-author" title="Permalink to this headline">¶</a></h2>
|
|
<p>Ansible was originally developed by <a class="reference external" href="http://michaeldehaan.net">Michael DeHaan</a> (<a class="reference external" href="http://twitter.com/#!/laserllama">@laserllama</a>), a Raleigh, NC
|
|
based software developer and architect. He created other popular
|
|
DevOps programs such as <a class="reference external" href="http://cobbler.github.com/">Cobbler</a>, the popular Linux install server.
|
|
Cobbler is used to deploy mission critical systems all over the
|
|
planet, in industries ranging from massively multiplayer gaming, core
|
|
internet infrastructure, finance, chip design, and more. Michael also
|
|
helped co-author of <a class="reference external" href="http://fedorahosted.org/func/">Func</a>, a precursor to Ansible, which is used to
|
|
orchestrate systems in lots of diverse places. He’s worked on systems
|
|
software for IBM, Motorola, Red Hat’s Emerging Technologies Group,
|
|
