Ansible
|
|
=======
|
|
|
|
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.
|
|
|
|
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".
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
Systems management doesn't have to be complicated. Ansible's docs will remain
|
|
short & simple, and the source will be blindingly obvious.
|
|

Design Goals
|
|
````````````
|
|
|
|
* Dead simple setup
|
|
* Super fast & parallel by default
|
|
* No server or client daemons; use existing SSHd out of the box
|
|
* No additional software required on client boxes
|
|
* Modules can be written in ANY language
|
|
* Awesome API for creating very powerful distributed scripts
|
|
* Be very usable as non-root
|
|
* Create the easiest config management system to use, ever.
|
|
|
|
Communicate and Get Involved

About the Author
|
|
````````````````
|
|
|
|
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.
