<h1>Ansible<a class="headerlink" href="#ansible" title="Permalink to this headline">¶</a></h1>

|
<p>Ansible is a extra-simple tool/API for doing ‘parallel remote things’
|
||
|
|
over SSH – whether executing commands, running “modules”, or
|
||
|
|
executing larger ‘playbooks’ that can serve as a configuration
|
||
|
|
management or deployment system.</p>
|
||
|
|
<p>While <a class="reference external" href="http://fedorahosted.org/func">Func installation</a> which I
|
||
|
|
co-wrote, aspired to avoid using SSH and have it’s own daemon
|
||
|
|
infrastructure, Ansible aspires to be quite different and more
|
||
|
|
minimal, but still able to grow more modularly over time. This is
|
||
|
|
based on talking to a lot of users of various tools and wishing to
|
||
|
|
eliminate problems with connectivity and long running daemons, or not
|
||
|
|
picking tool X because they preferred to code in Y. Further, playbooks
|
||
|
|
take things a whole step further, building the config and deployment
|
||
|
|
system I always wanted to build.</p>
|
||
|
|
<p>Why use Ansible versus something else? (Fabric, Capistrano,
|
||
|
|
mCollective, Func, SaltStack, etc?) It will have far less code, it
|
||
|
|
will be 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.
|
||
|
|
Want to only code plugins in bash or clojure? Ansible doesn’t care.
|
||
|
|
The docs will fit on one page and the source will be blindingly
|
||
|
|
obvious.</p>

<li>simplejson</li>
