The Python API is very powerful, and is how the ansible CLI and ansible-playbook
are implemented.
It's pretty simple::
import ansible.runner
runner = ansible.runner.Runner(
module_name='ping',
module_args='',
pattern='web*',
forks=10
)
datastructure = runner.run()
The run method returns results per host, grouped by whether they
could be contacted or not. Return types are module specific, as
expressed in the 'ansible-modules' documentation.::
{
"dark" : {
"web1.example.com" : "failure message"
}
"contacted" : {
"web2.example.com" : 1
}
}
A module can return any type of JSON data it wants, so Ansible can
be used as a framework to rapidly build powerful applications and scripts.

Alternative ways to use ansible
Parallelism and Shell Commands
``````````````````````````````
Reboot all web servers in Atlanta, 10 at a time::
ssh-agent bash
ssh-add ~/.ssh/id_rsa.pub
ansible atlanta -a "/sbin/reboot" -f 10
The -f 10 specifies the usage of 10 simultaneous processes.
Note that other than the command module, ansible modules do not work like simple scripts. They make the remote system look like you state, and run the commands neccessary to get it there.
Example 2: Time Limited Background Operations
`````````````````````````````````````````````
Long running operations can be backgrounded, and their status can be checked on later. The same job ID is given to the same task on all hosts, so you won't lose track. Polling support is pending in the command line.::
ansible all -B 3600 -a "/usr/bin/long_running_operation --do-stuff"
ansible all -n job_status -a jid=123456789
Any module other than 'copy' or 'template' can be backgrounded.
Examples 3: File Transfer & Templating
``````````````````````````````````````
Ansible can SCP lots of files to multiple machines in parallel, and optionally use them as template sources.
To just transfer a file directly to many different servers::
ansible atlanta copy -a "/etc/hosts /tmp/hosts"
To use templating, first run the setup module to put the template variables you would like to use on the remote host. Then use the template module to write the files using the templates. Templates are written in Jinja2 format. Playbooks (covered below) will run the setup module for you, making this even simpler.::
ansible webservers -m setup -a "favcolor=red ntp_server=192.168.1.1"
ansible webservers -m template -a "src=/srv/motd.j2 dest=/etc/motd"
ansible webservers -m template -a "src=/srv/ntp.j2 dest=/etc/ntp.conf"
Need something like the fqdn in a template? If facter or ohai are installed, data from these projects will also be made available to the template engine, using 'facter' and 'ohai' prefixes for each.
Examples 3: Deploying From Source Control
`````````````````````````````````````````
Deploy your webapp straight from git::
ansible webservers -m git -a "repo=git://foo dest=/srv/myapp version=HEAD"
Since ansible modules can notify change handlers (see 'Playbooks') it is possible to tell ansible to run specific tasks when the code is updated, such as deploying Perl/Python/PHP/Ruby directly from git and then restarting apache.

Requirements
````````````
Requirements are extremely minimal.
If you are running python 2.6 on the **overlord** machine, you will
need:
* ``paramiko``
* ``PyYAML``
* ``python-jinja2`` (for playbooks)
If you are running less than Python 2.6, you will also need:
* The Python 2.4 or 2.5 backport of the ``multiprocessing`` module
- `Installation and Testing Instructions <http://code.google.com/p/python-multiprocessing/wiki/Install>`_
* ``simplejson``
On the managed nodes, to use templating, you will need:
* ``python-jinja2`` (you can install this with ansible)
Developer Requirements
``````````````````````
For developers, you may wish to have:
* ``asciidoc`` (for building manpage documentation)
* ``python-sphinx`` (for building content for ansible.github.com)
Getting Ansible
```````````````
Tagged releases are available as tar.gz files from the Ansible github
project page:
* `Ansible/downloads <https://github.com/ansible/ansible/downloads>`_
You can also clone the git repository yourself and install Ansible in
one of two ways:
Python Distutils
++++++++++++++++
You can also install Ansible using Python Distutils::
$ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ sudo make install
Via RPM
+++++++
In the near future, pre-built RPMs will be available through your distribution. Until that time you
can use the ``make rpm`` command::
$ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ make rpm
$ sudo rpm -Uvh ~/rpmbuild/RPMS/noarch/ansible-1.0-1.noarch.rpm
Your first commands
```````````````````
Edit /etc/ansible/hosts and put one or more remote systems in it, for which you have your SSH
key in ``authorized_keys``::
192.168.1.50
aserver.example.org
bserver.example.org
Now try this:
ssh-agent bash
ssh-add ~/.ssh/id_rsa
ansible all -m ping
Congratulations. You've just contacted your nodes with Ansible. It's now time to read some
of the more real-world examples.

Ansible
=======
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.
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.
While `Func installation <http://fedorahosted.org/func>`_ 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.
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 the "playbooks" feature.
Why use Ansible versus something else? (Fabric, Capistrano,
Ansible does not require programming in any particular language -- you can write modules
as scripts or programs that return simple JSON.

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

Requirements
````````````
Requirements are extremely minimal.
If you are running python 2.6 on the **overlord** machine, you will
need:
* ``paramiko``
* ``PyYAML``
* ``python-jinja2`` (for playbooks)
* ``Asciidoc`` (for building documentation)
If you are running less than Python 2.6, you will also need:
* The Python 2.4 or 2.5 backport of the ``multiprocessing`` module
- `Installation and Testing Instructions <http://code.google.com/p/python-multiprocessing/wiki/Install>`_
* ``simplejson``
On the managed nodes, to use templating, you will need:
* ``python-jinja2`` (you can install this with ansible)
Getting Ansible
```````````````
Tagged releases are available as tar.gz files from the Ansible github
project page:
Michael DeHaan is a Raleigh, NC based software developer and architect. He created other
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, which is used
to orchestrate systems in lots of diverse places.
* `Ansible/downloads <https://github.com/ansible/ansible/downloads>`_
You can also clone the git repository yourself and install Ansible in
one of two ways:
Python Distutils
++++++++++++++++
You can install Ansible using Python Distutils::
$ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ sudo make install
Via RPM
+++++++
In the future, pre-built RPMs may be available. Until that time you
can use the ``make rpm`` command::
$ git clone git://github.com/ansible/ansible.git
$ cd ./ansible
$ make rpm
$ sudo rpm -Uvh ~/rpmbuild/RPMS/noarch/ansible-1.0-1.noarch.rpm
Ansible is an GPLv3 licensed open source project, so see the contributions section for how to

About Modules
`````````````
Ansible ships with a number of modules that can be executed directly on remote hosts or through
ansible playbooks.
Idempotence
```````````
Most modules other than command are idempotent, meaning they will seek to avoid changes
unless a change needs to be made. When using ansible playbooks, these modules can
trigger change events. Unless otherwise noted, all modules support change hooks.
command
```````
The command module takes the command name followed by a list of arguments, space delimited.
This is the only module that does not use key=value style parameters.
Example usage::
/sbin/shutdown -t now
This module does not support change hooks and returns the return code from the program as well as timing information about how long the command was running for.
copy
````
The copy module moves a file on the local box to remote locations.
*src*::
Local absolute path to a file to copy to the remote server
*dest*::
Remote absolute path where the file should end up
This module also returns md5sum information about the resultant file.
facter
``````
Runs the discovery program 'facter' on the remote system, returning
JSON data that can be useful for inventory purposes.
Requires that 'facter' and 'ruby-json' be installed on the remote end.
This module is informative only - it takes no parameters & does not support change hooks,
nor does it make any changes on the system.
git
```
Deploys software from git checkouts.
*repo*::
git or http protocol address of the repo to checkout
*dest*::
where to check it out, an absolute directory path
*version*::
what version to check out -- either the git SHA, the literal string 'HEAD', or a tag name
ohai
````
Similar to the facter module, this returns JSON inventory data. Ohai
data is a bit more verbose and nested than facter.
Requires that 'ohai' be installed on the remote end.
This module is information only - it takes no parameters & does not
support change hooks, nor does it make any changes on the system.
ping
````
A trivial test module, this module always returns the integer '1' on
successful contact.
This module does not support change hooks.
This module is informative only - it takes no parameters & does not
support change hooks, nor does it make any changes on the system.
service
```````
Controls services on remote machines.
*state*
Values are 'started', 'stopped', or 'restarted'. Started/stopped
are idempotent actions that will not run commands unless neccessary.
'restarted' will always bounce the service
*name*
The name of the service
setup
`````
Writes a JSON file containing key/value data, for use in templating.
Call this once before using the template modules. Playbooks will
execute this module automatically as the first step in each play.
If facter or ohai are installed, variables from these programs will also
be snapshotted into the JSON file for usage in templating. These variables
are prefixed with 'facter_' and 'ohai_" so it's easy to tell their source.
*metadata*
Optionally overrides the default JSON file location of /etc/ansible/setup or ~/ansible/setup
depending on what remote user has been specified.
If used, also supply the metadata parameter to the template module.
*anything*
any other parameters can be named basically anything, and set a key=value
pair in the JSON file for use in templating.
template
````````
Templates a file out to a remote server. Call the setup module prior to usage.
*src*
path of a Jinja2 formatted template on the local server
*dest*
location to render the template on the remote server
*metadata*
location of a JSON file to use to supply template data. Default is /etc/ansible/setup
which is the same as the default for the setup module. Change if running as a non-root
remote user who does not have permissions on /etc/ansible.
This module also returns md5sum information about the resultant file.
user
````
This module is in plan.
yum
```
This module is in plan.
WRITING YOUR OWN MODULES
````````````````````````
To write your own modules, simply follow the convention of those already available in
/usr/share/ansible. Modules must return JSON but can be written in any language.
Modules should return hashes, but hashes can be nested.
To support change hooks, modules should return hashes with a changed: True/False
element at the top level. Modules can also choose to indicate a failure scenario
by returning a top level 'failure' element with a True value, and a 'msg' element
describing the nature of the failure. Other values are up to the module.

How to select hosts you wish to manage
.. seealso::
:doc:`examples`
Examples of basic commands
:doc:`playbooks`
Learning ansible's configuration management language
Ansible works against multiple systems in your infrastructure at the
same time. It does this by selecting portions of systems listed in Ansible's inventory file,
which defaults to /etc/ansible/hosts, and looks like this::
mail.example.com
[webservers]
foo.example.com
bar.example.com
[dbservers]
one.example.com
two.example.com
three.example.com
Targetting All Systems
``````````````````````
The pattern 'all' or '*' targets all systems in the inventory file.
Specific Hosts
``````````````
It is possible to address specific hosts:
one.example.com
one.example.com:two.example.com
Groups
``````
The following patterns address one or more groups:
webservers
webservers:dbservers
There is also a magic group 'ungrouped' which selects systems not in a group.
Wildcards
`````````
Individual hosts, but not groups, can also be referenced using wildcards:
*.example.com
*.com
Mixing Things Up
````````````````
Specific hosts, wildcards, and groups can all be mixed in the same pattern
one*.com:dbservers
It is not possible to target a host not in the inventory file.

Learn about how to select hosts
Playbooks are a completely different way to use ansible and are particularly awesome.
They are the basis for a really simple configuration management and deployment system, unlike any that already exist, and one that is very well suited to deploying complex multi-machine applications. While you might run the main ansible program for ad-hoc tasks, playbooks are more likely to be kept in source control and used to push out your configuration or assure the configurations of your remote systems are in spec.
Playbook Example
````````````````
Playbooks are expressed in YAML format and have a minimum of syntax. Each playbook is composed
of one or more patterns in a list. By composing a playbook of multiple patterns, it is possible
to orchestrate multi-machine deployments, running certain steps on all machines in
the webservers group, then certain steps on the database server group, then more commands
back on the webservers group, etc::
---
- hosts: all
vars:
http_port: 80
max_clients: 200
user: root
tasks:
- include: base.yml somevar=3 othervar=4
- name: write the apache config file
action: template src=/srv/httpd.j2 dest=/etc/httpd.conf
notify:
- restart apache
- name: ensure apache is running
action: service name=httpd state=started
handlers:
- include: handlers.yml
Hosts line
``````````
The hosts line is alist of one or more groups or host patterns, seperated by colons.
webservers:dbservers:*.foo.example.com
Vars section
````````````
A list of variables that can be used in the 'action' lines of the template, or in
included templates. Variables are deferenced like this::
{{ varname }}
These variables will be pushed down to the managed systems for use in templating operations.
Further, if there are discovered variables about the system (say, if facter or ohai were
installed) these variables bubble up back into the playbook, and can be used on each
system just like explicitly set variables. Facter variables are prefixed with 'facter'
and Ohai variables are prefixed with 'ohai'.
Tasks list
``````````
Tasks are executed in order, one at a time, against all machines matched by the host
pattern, before moving on to the next task. Failed tasks are taken out of the rotation.
Task name and comment
`````````
Each task has a name (required) and optional comment. This is for informational purposes only
Task action
```````````
The action line is the name of an ansible module followed by parameters. Usually these
are expressed in key=value form, except for the command module, which looks just like a Linux/Unix
command line. See the module documentation for more info.
Notify statements
`````````````````
Nearly all modules are written to be 'idempotent' and can signal when they have affected a change
on the remote system. If a notify statement is used, the named handler will be run against
each system where a change was effected, but NOT on systems where no change occurred.
Handlers
````````
Handlers are lists of tasks, not really any different from regular tasks, that are referenced
by name.
Includes
````````
Not all tasks have to be listed directly in the main file. An include file can contain
a list of tasks (in YAML) as well, optionally passing extra variables into the file.
Variables passed in can be deferenced like this:
{{ variable }}
Asynchronous Actions and Polling

<p>The Python API is very powerful, and is how the ansible CLI and ansible-playbook
are implemented.</p>
<p>It&#8217;s pretty simple:</p>
<div class="highlight-python"><div class="highlight"><pre><span class="kn">import</span> <span class="nn">ansible.runner</span>
<span class="n">runner</span> <span class="o">=</span> <span class="n">ansible</span><span class="o">.</span><span class="n">runner</span><span class="o">.</span><span class="n">Runner</span><span class="p">(</span>
<span class="n">module_name</span><span class="o">=</span><span class="s">&#39;ping&#39;</span><span class="p">,</span>
<span class="n">module_args</span><span class="o">=</span><span class="s">&#39;&#39;</span><span class="p">,</span>
<span class="n">pattern</span><span class="o">=</span><span class="s">&#39;web*&#39;</span><span class="p">,</span>
<span class="n">forks</span><span class="o">=</span><span class="mi">10</span>
<span class="p">)</span>
<span class="n">datastructure</span> <span class="o">=</span> <span class="n">runner</span><span class="o">.</span><span class="n">run</span><span class="p">()</span>
</pre></div>
</div>
<p>The run method returns results per host, grouped by whether they
could be contacted or not. Return types are module specific, as
expressed in the &#8216;ansible-modules&#8217; documentation.:</p>
<div class="highlight-python"><pre>{
"dark" : {
"web1.example.com" : "failure message"
}
"contacted" : {
"web2.example.com" : 1
}
}</pre>
</div>
<p>A module can return any type of JSON data it wants, so Ansible can
be used as a framework to rapidly build powerful applications and scripts.</p>

</div>
<p>The -f 10 specifies the usage of 10 simultaneous processes.</p>

<p>Long running operations can be backgrounded, and their status can be checked on later. The same job ID is given to the same task on all hosts, so you won&#8217;t lose track. Polling support is pending in the command line.:</p>

<h2>Examples 3: File Transfer &amp; Templating<a class="headerlink" href="#examples-3-file-transfer-templating" title="Permalink to this headline"></a></h2>
<p>Ansible can SCP lots of files to multiple machines in parallel, and optionally use them as template sources.</p>
<p>To just transfer a file directly to many different servers:</p>
<div class="highlight-python"><pre>ansible atlanta copy -a "/etc/hosts /tmp/hosts"</pre>
</div>
<p>To use templating, first run the setup module to put the template variables you would like to use on the remote host. Then use the template module to write the files using the templates. Templates are written in Jinja2 format. Playbooks (covered below) will run the setup module for you, making this even simpler.:</p>
<div class="highlight-python"><pre>ansible webservers -m setup -a "favcolor=red ntp_server=192.168.1.1"

<h1>Ansible<a class="headerlink" href="#ansible" title="Permalink to this headline"></a></h1>
<p>Ansible is a extra-simple tool/API for doing &#8216;parallel remote things&#8217;
over SSH &#8211; whether executing commands, running &#8220;modules&#8221;, or
executing larger &#8216;playbooks&#8217; 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&#8217;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 <cite>X</cite> because they preferred to code in <cite>Y</cite>. 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,
<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&#8217;s core is a little over 1000 lines.</p>
<p>Ansible isn&#8217;t just for configuration &#8211; it&#8217;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 the &#8220;playbooks&#8221; feature.</p>
<p>Ansible does not require programming in any particular language &#8211; you can write modules
as scripts or programs that return simple JSON.</p>
<p>Why use Ansible versus something else? (Puppet, Chef, 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&#8217;ll ever see &#8211; regardless of your favorite language of choice.
Want to only code plugins in bash or clojure? Ansible doesn&#8217;t care.
The docs will fit on one page and the source will be blindingly
obvious.</p>

<div class="section" id="about-modules">
<h2>About Modules<a class="headerlink" href="#about-modules" title="Permalink to this headline"></a></h2>
<p>Ansible ships with a number of modules that can be executed directly on remote hosts or through
ansible playbooks.</p>
</div>
<div class="section" id="idempotence">
<h2>Idempotence<a class="headerlink" href="#idempotence" title="Permalink to this headline"></a></h2>
<p>Most modules other than command are idempotent, meaning they will seek to avoid changes
unless a change needs to be made. When using ansible playbooks, these modules can
trigger change events. Unless otherwise noted, all modules support change hooks.</p>
</div>
<div class="section" id="command">
<h2>command<a class="headerlink" href="#command" title="Permalink to this headline"></a></h2>
<p>The command module takes the command name followed by a list of arguments, space delimited.
This is the only module that does not use key=value style parameters.</p>
<p>Example usage:</p>
<div class="highlight-python"><pre>/sbin/shutdown -t now</pre>
</div>
<p>This module does not support change hooks and returns the return code from the program as well as timing information about how long the command was running for.</p>
</div>
<div class="section" id="copy">
<h2>copy<a class="headerlink" href="#copy" title="Permalink to this headline"></a></h2>
<p>The copy module moves a file on the local box to remote locations.</p>
<p><em>src</em>:</p>
<p>Local absolute path to a file to copy to the remote server</p>
<p><em>dest</em>:</p>
<p>Remote absolute path where the file should end up</p>
<p>This module also returns md5sum information about the resultant file.</p>
</div>
<div class="section" id="facter">
<h2>facter<a class="headerlink" href="#facter" title="Permalink to this headline"></a></h2>
<p>Runs the discovery program &#8216;facter&#8217; on the remote system, returning
JSON data that can be useful for inventory purposes.</p>
<p>Requires that &#8216;facter&#8217; and &#8216;ruby-json&#8217; be installed on the remote end.</p>
<p>This module is informative only - it takes no parameters &amp; does not support change hooks,
nor does it make any changes on the system.</p>
</div>
<div class="section" id="git">
<h2>git<a class="headerlink" href="#git" title="Permalink to this headline"></a></h2>
<p>Deploys software from git checkouts.</p>
<p><em>repo</em>:</p>
<p>git or http protocol address of the repo to checkout</p>
<p><em>dest</em>:</p>
<p>where to check it out, an absolute directory path</p>
<p><em>version</em>:</p>
<p>what version to check out &#8211; either the git SHA, the literal string &#8216;HEAD&#8217;, or a tag name</p>
</div>
<div class="section" id="ohai">
<h2>ohai<a class="headerlink" href="#ohai" title="Permalink to this headline"></a></h2>
<p>Similar to the facter module, this returns JSON inventory data. Ohai
data is a bit more verbose and nested than facter.</p>
<p>Requires that &#8216;ohai&#8217; be installed on the remote end.</p>
<p>This module is information only - it takes no parameters &amp; does not
support change hooks, nor does it make any changes on the system.</p>
</div>
<div class="section" id="ping">
<h2>ping<a class="headerlink" href="#ping" title="Permalink to this headline"></a></h2>
<p>A trivial test module, this module always returns the integer &#8216;1&#8217; on
successful contact.</p>
<p>This module does not support change hooks.</p>
<p>This module is informative only - it takes no parameters &amp; does not
support change hooks, nor does it make any changes on the system.</p>
</div>
<div class="section" id="service">
<h2>service<a class="headerlink" href="#service" title="Permalink to this headline"></a></h2>
<p>Controls services on remote machines.</p>
<p><em>state</em></p>
<p>Values are &#8216;started&#8217;, &#8216;stopped&#8217;, or &#8216;restarted&#8217;. Started/stopped
are idempotent actions that will not run commands unless neccessary.
&#8216;restarted&#8217; will always bounce the service</p>
<p><em>name</em></p>
<p>The name of the service</p>
</div>
<div class="section" id="setup">
<h2>setup<a class="headerlink" href="#setup" title="Permalink to this headline"></a></h2>
<p>Writes a JSON file containing key/value data, for use in templating.
Call this once before using the template modules. Playbooks will
execute this module automatically as the first step in each play.</p>
<p>If facter or ohai are installed, variables from these programs will also
be snapshotted into the JSON file for usage in templating. These variables
are prefixed with &#8216;<a class="reference internal" href="#facter">facter</a>&#8216; and &#8216;<a class="reference internal" href="#ohai">ohai</a>&#8221; so it&#8217;s easy to tell their source.</p>
<p><em>metadata</em></p>
<p>Optionally overrides the default JSON file location of /etc/ansible/setup or ~/ansible/setup
depending on what remote user has been specified.</p>
<p>If used, also supply the metadata parameter to the template module.</p>
<p><em>anything</em></p>
<p>any other parameters can be named basically anything, and set a key=value
pair in the JSON file for use in templating.</p>
</div>
<div class="section" id="template">
<h2>template<a class="headerlink" href="#template" title="Permalink to this headline"></a></h2>
<p>Templates a file out to a remote server. Call the setup module prior to usage.</p>
<p><em>src</em></p>
<p>path of a Jinja2 formatted template on the local server</p>
<p><em>dest</em></p>
<p>location to render the template on the remote server</p>
<p><em>metadata</em></p>
<p>location of a JSON file to use to supply template data. Default is /etc/ansible/setup
which is the same as the default for the setup module. Change if running as a non-root
remote user who does not have permissions on /etc/ansible.</p>
<p>This module also returns md5sum information about the resultant file.</p>
</div>
<div class="section" id="user">
<h2>user<a class="headerlink" href="#user" title="Permalink to this headline"></a></h2>
<p>This module is in plan.</p>
</div>
<div class="section" id="yum">
<h2>yum<a class="headerlink" href="#yum" title="Permalink to this headline"></a></h2>
<p>This module is in plan.</p>
</div>
<div class="section" id="writing-your-own-modules">
<h2>WRITING YOUR OWN MODULES<a class="headerlink" href="#writing-your-own-modules" title="Permalink to this headline"></a></h2>
<p>To write your own modules, simply follow the convention of those already available in
/usr/share/ansible. Modules must return JSON but can be written in any language.
Modules should return hashes, but hashes can be nested.
To support change hooks, modules should return hashes with a changed: True/False
element at the top level. Modules can also choose to indicate a failure scenario
by returning a top level &#8216;failure&#8217; element with a True value, and a &#8216;msg&#8217; element
describing the nature of the failure. Other values are up to the module.</p>

which defaults to /etc/ansible/hosts, and looks like this:</p>

<p>Playbooks are a completely different way to use ansible and are particularly awesome.</p>
<p>They are the basis for a really simple configuration management and deployment system, unlike any that already exist, and one that is very well suited to deploying complex multi-machine applications. While you might run the main ansible program for ad-hoc tasks, playbooks are more likely to be kept in source control and used to push out your configuration or assure the configurations of your remote systems are in spec.</p>
<div class="section" id="playbook-example">
<h2>Playbook Example<a class="headerlink" href="#playbook-example" title="Permalink to this headline"></a></h2>
<p>Playbooks are expressed in YAML format and have a minimum of syntax. Each playbook is composed
of one or more patterns in a list. By composing a playbook of multiple patterns, it is possible
to orchestrate multi-machine deployments, running certain steps on all machines in
the webservers group, then certain steps on the database server group, then more commands
back on the webservers group, etc:</p>
<div class="highlight-python"><pre>---
- hosts: all</pre>
</div>
<blockquote>
<div><dl class="docutils">
<dt>vars:</dt>
<dd>http_port: 80
max_clients: 200</dd>
</dl>
<p>user: root
tasks:
- include: base.yml somevar=3 othervar=4
- name: write the apache config file</p>
<blockquote>
<div>action: template src=/srv/httpd.j2 dest=/etc/httpd.conf
notify:
- restart apache</div></blockquote>
<ul class="simple">
<li>name: ensure apache is running
action: service name=httpd state=started</li>
</ul>
<dl class="docutils">
<dt>handlers:</dt>
<dd><ul class="first last simple">
<li>include: handlers.yml</li>
</ul>
</dd>
</dl>
</div></blockquote>
</div>
<div class="section" id="hosts-line">
<h2>Hosts line<a class="headerlink" href="#hosts-line" title="Permalink to this headline"></a></h2>
<p>The hosts line is alist of one or more groups or host patterns, seperated by colons.</p>
<blockquote>
<div>webservers:dbservers:<a href="#id1"><span class="problematic" id="id2">*</span></a>.foo.example.com</div></blockquote>
</div>

<h2>Vars section<a class="headerlink" href="#vars-section" title="Permalink to this headline"></a></h2>
<p>A list of variables that can be used in the &#8216;action&#8217; lines of the template, or in
included templates. Variables are deferenced like this:</p>
<div class="highlight-python"><pre>{{ varname }}</pre>
</div>
<p>These variables will be pushed down to the managed systems for use in templating operations.</p>
<p>Further, if there are discovered variables about the system (say, if facter or ohai were
installed) these variables bubble up back into the playbook, and can be used on each
system just like explicitly set variables. Facter variables are prefixed with &#8216;facter&#8217;
and Ohai variables are prefixed with &#8216;ohai&#8217;.</p>
</div>
<div class="section" id="tasks-list">
<h2>Tasks list<a class="headerlink" href="#tasks-list" title="Permalink to this headline"></a></h2>
<p>Tasks are executed in order, one at a time, against all machines matched by the host
pattern, before moving on to the next task. Failed tasks are taken out of the rotation.</p>
</div>
<div class="section" id="task-name-and-comment">
<h2>Task name and comment<a class="headerlink" href="#task-name-and-comment" title="Permalink to this headline"></a></h2>
<p>Each task has a name (required) and optional comment. This is for informational purposes only</p>
</div>
<div class="section" id="task-action">
<h2>Task action<a class="headerlink" href="#task-action" title="Permalink to this headline"></a></h2>
<p>The action line is the name of an ansible module followed by parameters. Usually these
are expressed in key=value form, except for the command module, which looks just like a Linux/Unix
command line. See the module documentation for more info.</p>
</div>
<div class="section" id="notify-statements">
<h2>Notify statements<a class="headerlink" href="#notify-statements" title="Permalink to this headline"></a></h2>
<p>Nearly all modules are written to be &#8216;idempotent&#8217; and can signal when they have affected a change
on the remote system. If a notify statement is used, the named handler will be run against
each system where a change was effected, but NOT on systems where no change occurred.</p>
</div>
<div class="section" id="handlers">
<h2>Handlers<a class="headerlink" href="#handlers" title="Permalink to this headline"></a></h2>
<p>Handlers are lists of tasks, not really any different from regular tasks, that are referenced
by name.</p>
</div>
<div class="section" id="includes">
<h2>Includes<a class="headerlink" href="#includes" title="Permalink to this headline"></a></h2>
<p>Not all tasks have to be listed directly in the main file. An include file can contain
a list of tasks (in YAML) as well, optionally passing extra variables into the file.
Variables passed in can be deferenced like this:</p>

The Python API is very powerful, and is how the ansible CLI and ansible-playbook
are implemented.
It's pretty simple::
import ansible.runner
runner = ansible.runner.Runner(
module_name='ping',
module_args='',
pattern='web*',
forks=10
)
datastructure = runner.run()
The run method returns results per host, grouped by whether they
could be contacted or not. Return types are module specific, as
expressed in the 'ansible-modules' documentation.::
{
"dark" : {
"web1.example.com" : "failure message"
}
"contacted" : {
"web2.example.com" : 1
}
}
A module can return any type of JSON data it wants, so Ansible can
be used as a framework to rapidly build powerful applications and scripts.

Alternative ways to use ansible
Parallelism and Shell Commands
``````````````````````````````
Reboot all web servers in Atlanta, 10 at a time::
ssh-agent bash
ssh-add ~/.ssh/id_rsa.pub
ansible atlanta -a "/sbin/reboot" -f 10
The -f 10 specifies the usage of 10 simultaneous processes.
Note that other than the command module, ansible modules do not work like simple scripts. They make the remote system look like you state, and run the commands neccessary to get it there.
Example 2: Time Limited Background Operations
`````````````````````````````````````````````
Long running operations can be backgrounded, and their status can be checked on later. The same job ID is given to the same task on all hosts, so you won't lose track. Polling support is pending in the command line.::
ansible all -B 3600 -a "/usr/bin/long_running_operation --do-stuff"
ansible all -n job_status -a jid=123456789
Any module other than 'copy' or 'template' can be backgrounded.
Examples 3: File Transfer & Templating
``````````````````````````````````````
Ansible can SCP lots of files to multiple machines in parallel, and optionally use them as template sources.
To just transfer a file directly to many different servers::
ansible atlanta copy -a "/etc/hosts /tmp/hosts"
To use templating, first run the setup module to put the template variables you would like to use on the remote host. Then use the template module to write the files using the templates. Templates are written in Jinja2 format. Playbooks (covered below) will run the setup module for you, making this even simpler.::
ansible webservers -m setup -a "favcolor=red ntp_server=192.168.1.1"
ansible webservers -m template -a "src=/srv/motd.j2 dest=/etc/motd"
ansible webservers -m template -a "src=/srv/ntp.j2 dest=/etc/ntp.conf"
Need something like the fqdn in a template? If facter or ohai are installed, data from these projects will also be made available to the template engine, using 'facter' and 'ohai' prefixes for each.
Examples 3: Deploying From Source Control
`````````````````````````````````````````
Deploy your webapp straight from git::
ansible webservers -m git -a "repo=git://foo dest=/srv/myapp version=HEAD"
Since ansible modules can notify change handlers (see 'Playbooks') it is possible to tell ansible to run specific tasks when the code is updated, such as deploying Perl/Python/PHP/Ruby directly from git and then restarting apache.

Ansible
=======
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.
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.
While `Func installation <http://fedorahosted.org/func>`_ 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.
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 the "playbooks" feature.
Why use Ansible versus something else? (Fabric, Capistrano,
Ansible does not require programming in any particular language -- you can write modules
as scripts or programs that return simple JSON.
Why use Ansible versus something else? (Puppet, Chef, 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.
Systems management doesn't have to be complicated. Ansible's docs will remain
short & simple, and the source will be blindingly obvious.
Design Principles
`````````````````
Design Goals
````````````
* Dead simple setup
* Super fast & parallel by default
* No server or client daemons; use existing SSHd
* 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 usable as non-root
* Create the easiest config management system to use, ever.

About Modules
`````````````
Ansible ships with a number of modules that can be executed directly on remote hosts or through
ansible playbooks.
Idempotence
```````````
Most modules other than command are idempotent, meaning they will seek to avoid changes
unless a change needs to be made. When using ansible playbooks, these modules can
trigger change events. Unless otherwise noted, all modules support change hooks.
command
```````
The command module takes the command name followed by a list of arguments, space delimited.
This is the only module that does not use key=value style parameters.
Example usage::
/sbin/shutdown -t now
This module does not support change hooks and returns the return code from the program as well as timing information about how long the command was running for.
copy
````
The copy module moves a file on the local box to remote locations.
*src*::
Local absolute path to a file to copy to the remote server
*dest*::
Remote absolute path where the file should end up
This module also returns md5sum information about the resultant file.
facter
``````
Runs the discovery program 'facter' on the remote system, returning
JSON data that can be useful for inventory purposes.
Requires that 'facter' and 'ruby-json' be installed on the remote end.
This module is informative only - it takes no parameters & does not support change hooks,
nor does it make any changes on the system.
git
```
Deploys software from git checkouts.
*repo*::
git or http protocol address of the repo to checkout
*dest*::
where to check it out, an absolute directory path
*version*::
what version to check out -- either the git SHA, the literal string 'HEAD', or a tag name
ohai
````
Similar to the facter module, this returns JSON inventory data. Ohai
data is a bit more verbose and nested than facter.
Requires that 'ohai' be installed on the remote end.
This module is information only - it takes no parameters & does not
support change hooks, nor does it make any changes on the system.
ping
````
A trivial test module, this module always returns the integer '1' on
successful contact.
This module does not support change hooks.
This module is informative only - it takes no parameters & does not
support change hooks, nor does it make any changes on the system.
service
```````
Controls services on remote machines.
*state*
Values are 'started', 'stopped', or 'restarted'. Started/stopped
are idempotent actions that will not run commands unless neccessary.
'restarted' will always bounce the service
*name*
The name of the service
setup
`````
Writes a JSON file containing key/value data, for use in templating.
Call this once before using the template modules. Playbooks will
execute this module automatically as the first step in each play.
If facter or ohai are installed, variables from these programs will also
be snapshotted into the JSON file for usage in templating. These variables
are prefixed with 'facter_' and 'ohai_" so it's easy to tell their source.
*metadata*
Optionally overrides the default JSON file location of /etc/ansible/setup or ~/ansible/setup
depending on what remote user has been specified.
If used, also supply the metadata parameter to the template module.
*anything*
any other parameters can be named basically anything, and set a key=value
pair in the JSON file for use in templating.
template
````````
Templates a file out to a remote server. Call the setup module prior to usage.
*src*
path of a Jinja2 formatted template on the local server
*dest*
location to render the template on the remote server
*metadata*
location of a JSON file to use to supply template data. Default is /etc/ansible/setup
which is the same as the default for the setup module. Change if running as a non-root
remote user who does not have permissions on /etc/ansible.
This module also returns md5sum information about the resultant file.
user
````
This module is in plan.
yum
```
This module is in plan.
WRITING YOUR OWN MODULES
````````````````````````
To write your own modules, simply follow the convention of those already available in
/usr/share/ansible. Modules must return JSON but can be written in any language.
Modules should return hashes, but hashes can be nested.
To support change hooks, modules should return hashes with a changed: True/False
element at the top level. Modules can also choose to indicate a failure scenario
by returning a top level 'failure' element with a True value, and a 'msg' element
describing the nature of the failure. Other values are up to the module.

Learning ansible's configuration management language
Ansible works against multiple systems in your infrastructure at the
same time. It does this by selecting portions of systems listed in Ansible's inventory file,
which defaults to /etc/ansible/hosts, and looks like this::
mail.example.com
[webservers]
foo.example.com
bar.example.com
[dbservers]
one.example.com
two.example.com
three.example.com
Targetting All Systems
``````````````````````
The pattern 'all' or '*' targets all systems in the inventory file.
Specific Hosts
``````````````
It is possible to address specific hosts:
one.example.com
one.example.com:two.example.com
Groups
``````
The following patterns address one or more groups:
webservers
webservers:dbservers
There is also a magic group 'ungrouped' which selects systems not in a group.
Wildcards
`````````
Individual hosts, but not groups, can also be referenced using wildcards:
*.example.com
*.com
Mixing Things Up
````````````````
Specific hosts, wildcards, and groups can all be mixed in the same pattern
one*.com:dbservers
It is not possible to target a host not in the inventory file.

Learn about how to select hosts
Playbooks are a completely different way to use ansible and are particularly awesome.
They are the basis for a really simple configuration management and deployment system, unlike any that already exist, and one that is very well suited to deploying complex multi-machine applications. While you might run the main ansible program for ad-hoc tasks, playbooks are more likely to be kept in source control and used to push out your configuration or assure the configurations of your remote systems are in spec.
Playbook Example
````````````````
Playbooks are expressed in YAML format and have a minimum of syntax. Each playbook is composed
of one or more patterns in a list. By composing a playbook of multiple patterns, it is possible
to orchestrate multi-machine deployments, running certain steps on all machines in
the webservers group, then certain steps on the database server group, then more commands
back on the webservers group, etc::
---
- hosts: all
vars:
http_port: 80
max_clients: 200
user: root
tasks:
- include: base.yml somevar=3 othervar=4
- name: write the apache config file
action: template src=/srv/httpd.j2 dest=/etc/httpd.conf
notify:
- restart apache
- name: ensure apache is running
action: service name=httpd state=started
handlers:
- include: handlers.yml
Hosts line
``````````
The hosts line is alist of one or more groups or host patterns, seperated by colons.::
webservers:dbservers:*.foo.example.com
Vars section
````````````
A list of variables that can be used in the 'action' lines of the template, or in
included templates. Variables are deferenced like this::
{{ varname }}
These variables will be pushed down to the managed systems for use in templating operations.
Further, if there are discovered variables about the system (say, if facter or ohai were
installed) these variables bubble up back into the playbook, and can be used on each
system just like explicitly set variables. Facter variables are prefixed with 'facter'
and Ohai variables are prefixed with 'ohai'.
Tasks list
``````````
Tasks are executed in order, one at a time, against all machines matched by the host
pattern, before moving on to the next task. Failed tasks are taken out of the rotation.
Task name and comment
`````````
Each task has a name (required) and optional comment. This is for informational purposes only
Task action
```````````
The action line is the name of an ansible module followed by parameters. Usually these
are expressed in key=value form, except for the command module, which looks just like a Linux/Unix
command line. See the module documentation for more info.
Notify statements
`````````````````
Nearly all modules are written to be 'idempotent' and can signal when they have affected a change
on the remote system. If a notify statement is used, the named handler will be run against
each system where a change was effected, but NOT on systems where no change occurred.
Handlers
````````
Handlers are lists of tasks, not really any different from regular tasks, that are referenced
by name.
Includes
````````
Not all tasks have to be listed directly in the main file. An include file can contain
a list of tasks (in YAML) as well, optionally passing extra variables into the file.
Variables passed in can be deferenced like this:
{{ variable }}
Asynchronous Actions and Polling
