<h1>Ansible<a class="headerlink" href="#ansible" title="Permalink to this headline">¶</a></h1>
|
|
<p>Ansible is a radically simple deployment, configuration, and command execution framework.
|
|
Other tools in this space 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. Where Ansible excels though, is expressing complex multi-node deployment processes, executing complex sequences of commands on different hosts through “playbooks”.</p>
|
|
<p>Extending ansible does not require programming in any particular language – you can write modules
|
|
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 Michael DeHaan, a Raleigh, NC based software developer and architect.
|
|
He created other popular DevOps programs such as Cobbler, 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 Func, 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, Puppet Labs, and rPath.</p>
