<h1>Playbooks<a class="headerlink" href="#playbooks" title="Permalink to this headline">¶</a></h1>
|
|
<p>Playbooks are a completely different way to use ansible and are
|
|
particularly awesome. They are the basis for a really simple
|
|
configuration management and multi-machine deployment system,
|
|
unlike any that already exist, and
|
|
one that is very well suited to deploying complex applications.</p>
|
|
<p>Playbooks can declare configurations, but they can also orchestrate steps of
|
|
any manual ordered process, even as different steps must bounce back and forth
|
|
between sets of machines in particular orders. They can launch tasks
|
|
synchronously or asynchronously.</p>
|
|
<p>While you might run the main /usr/bin/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>
|
|
<p>Let’s dive in and see how they work. As you go, you may wish to open
|
|
the <a class="reference external" href="https://github.com/ansible/ansible/tree/master/examples/playbooks">github examples directory</a> in
|
|
another tab, so you can apply the theory to what things look like in practice.</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 ‘plays’ in a list.</p>
|
|
<p>By composing a playbook of multiple ‘plays’, 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>
|
|
<p>For starters, here’s a playbook that contains just one play:</p>
|
|
<div class="highlight-python"><pre>---
|
|
- hosts: webservers
|
|
vars:
|
|
http_port: 80
|
|
max_clients: 200
|
|
user: root
|
|
tasks:
|
|
- name: ensure apache is at the latest version
|
|
action: yum pkg=httpd state=latest
|
|
- 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:
|
|
- name: restart apache
|
|
action: service name=apache state=restarted</pre>
|
|
</div>
|
|
<p>Below, we’ll break down what the various features of the playbook language are.</p>
|
|
</div>
|
|
<div class="section" id="basics">
|
|
<h2>Basics<a class="headerlink" href="#basics" title="Permalink to this headline">¶</a></h2>
|
|
<div class="section" id="hosts-and-users">
|
|
<h3>Hosts and Users<a class="headerlink" href="#hosts-and-users" title="Permalink to this headline">¶</a></h3>
|
|
<p>For each play in a playbook, you get to choose which machines in your infrastructure
|
|
to target and what remote user to complete the steps (called tasks) as.</p>
|
|
<p>The <cite>hosts</cite> line is a list of one or more groups or host patterns,
|
|
separated by colons, as described in the <a class="reference internal" href="patterns.html#patterns"><em>Inventory & Patterns</em></a>
|
|
documentation. The <cite>user</cite> is just the name of the user account:</p>
|
|
<div class="highlight-python"><pre>---
|
|
- hosts: webservers
|
|
user: root</pre>
|
|
</div>
|
|
<p>Support for running things from sudo is also available:</p>
|
|
<div class="highlight-python"><pre>---
|
|
- hosts: webservers
|
|
user: yourname
|
|
sudo: True</pre>
|
|
</div>
|
|
<p>You can also login as you, and then sudo to different users than root:</p>
|
|
<div class="highlight-python"><pre>---
|
|
- hosts: webservers
|
|
user: yourname
|
|
sudo: True
|
|
sudo_user: postgres</pre>
|
|
</div>
|
|
<p>If you need to specify a password to sudo, run <cite>ansible-playbook</cite> with <tt class="docutils literal"><span class="pre">--ask-sudo-pass</span></tt> (<cite>-K</cite>).
|
|
If you run a sudo playbook and the playbook seems to hang, it’s probably stuck at the sudo prompt.
|
|
Just <cite>Control-C</cite> to kill it and run it again with <cite>-K</cite>.</p>
|
|
<p>NOTE: When using <cite>sudo_user</cite> to a user other than root, the module arguments are briefly written into
|
|
a random tempfile in /tmp. These are deleted immediately after the command is executed. This only
|
|
occurs when sudoing from a user like ‘bob’ to ‘timmy’, not when going from ‘bob’ to ‘root’, or
|
|
logging in directly as ‘bob’ or ‘root’. If this concerns you that this data is briefly readable
|
|
(not writeable), avoid transferring uncrypted passwords with <cite>sudo_user</cite> set. In other cases, ‘/tmp’ is not used and
|
|
this does not come into play. Ansible also takes care to not log password parameters.</p>
|
|
</div>
|
|
<div class="section" id="vars-section">
|
|
<h3>Vars section<a class="headerlink" href="#vars-section" title="Permalink to this headline">¶</a></h3>
|
|
<p>The <cite>vars</cite> section contains a list of variables and values that can be used in the plays, like this:</p>
|
|
<div class="highlight-python"><pre>---
|
|
- hosts: webservers
|
|
users: root
|
|
vars:
|
|
http_port: 80
|
|
van_halen_port: 5150
|
|
other: 'magic'</pre>
|
|
</div>
|
|
<p>These variables can be used later in the playbook like this:</p>
|
|
<div class="highlight-python"><pre>$varname or ${varname}</pre>
|
|
</div>
|
|
<p>The later is useful in the event you need to do something like ${other}_concatenated_value.</p>
|
|
<p>The full power of the Jinja2 templating language is also available (note: in 0.4, this is only true inside of templates), which looks like this:</p>
|
|
<div class="highlight-python"><pre>{{ varname }}</pre>
|
|
</div>
|
|
<p>The Jinja2 documentation provides information about how to construct loops and conditionals for those
|
|
who which to use more advanced templating. This is optional and the $varname format still works in template
|
|
files.</p>
|
|
<p>If there are discovered variables about the system (ansible provides some of these,
|
|
plus we include ones taken from facter or ohai if installed) these variables bubble up back into the
|
|
playbook, and can be used on each system just like explicitly set
|
|
variables.</p>
|
|
<p>Facter variables are prefixed with <tt class="docutils literal"><span class="pre">facter_</span></tt> and Ohai
|
|
variables are prefixed with <tt class="docutils literal"><span class="pre">ohai_</span></tt>. Ansible variables (0.3 and later)
|
|
are not surprisingly prefixed with <tt class="docutils literal"><span class="pre">ansible_</span></tt> (See the <a class="reference internal" href="modules.html#setup"><em>setup</em></a> module
|
|
documentation for a list of Ansible variables).</p>
|
|
<p>So for instance, if I wanted
|
|
to write the hostname into the /etc/motd file, I could say:</p>
|
|
<div class="highlight-python"><pre>- name: write the motd
|
|
action: template src=/srv/templates/motd.j2 dest=/etc/motd</pre>
|
|
</div>
|
|
<p>And in /srv/templates/motd.j2:</p>
|
|
<div class="highlight-python"><pre>You are logged into {{ facter_hostname }}</pre>
|
|
</div>
|
|
<p>But we’re getting ahead of ourselves. Let’s talk about tasks.</p>
|
|
</div>
|
|
<div class="section" id="tasks-list">
|
|
<h3>Tasks list<a class="headerlink" href="#tasks-list" title="Permalink to this headline">¶</a></h3>
|
|
<p>Each play contains a list of tasks. Tasks are executed in order, one
|
|
at a time, against all machines matched by the host pattern,
|
|
before moving on to the next task.</p>
|
|
<p>Hosts with failed tasks are taken out of the rotation for the entire
|
|
playbook. If things fail, simply correct the playbook file and rerun.</p>
|
|
<p>The goal of each task is to execute a module, with very specific arguments.
|
|
Variables, as mentioned above, can be used in arguments to modules.</p>
|
|
<p>Modules other than <cite>command</cite> and <cite>shell</cite> are ‘idempotent’, meaning if you run them
|
|
again, they will make the changes they are told to make to bring the
|
|
system to the desired state. This makes it very safe to rerun
|
|
the same playbook multiple times. They won’t change things
|
|
unless they have to change things.</p>
|
|
<p>The <cite>command</cite> and <cite>shell</cite> modules will actually rerun the same command again,
|
|
which is totally ok if the command is something like
|
|
‘chmod’ or ‘setsebool’, etc.</p>
|
|
<p>Every task should have a <cite>name</cite>, which is included in the output from
|
|
running the playbook. This is output for humans, so it is
|
|
nice to have reasonably good descriptions of each task step. If the name
|
|
is not provided though, the string fed to ‘action’ will be used for
|
|
output.</p>
|
|
<p>Here is what a basic task looks like, as with most modules,
|
|
the service module takes key=value arguments:</p>
|
|
<div class="highlight-python"><pre>tasks:
|
|
- name: make sure apache is running
|
|
action: service name=httpd state=running</pre>
|
|
</div>
|
|
<p>The <cite>command</cite> and <cite>shell</cite> modules are the one modules that just takes a list
|
|
of arguments, and don’t use the key=value form. This makes
|
|
them work just like you would expect. Simple:</p>
|
|
<div class="highlight-python"><pre>tasks:
|
|
- name: disable selinux
|
|
action: command /sbin/setenforce 0</pre>
|
|
</div>
|
|
<p>Variables can be used in action lines. Suppose you defined
|
|
a variable called ‘vhost’ in the ‘vars’ section, you could do this:</p>
|
|
<div class="highlight-python"><pre>tasks:
|
|
- name: create a virtual host file for $vhost
|
|
action: template src=somefile.j2 dest=/etc/httpd/conf.d/$vhost</pre>
|
|
</div>
|
|
<p>Those same variables are usable in templates, which we’ll get to later.</p>
|
|
</div>
|
|
</div>
|
|
<div class="section" id="running-operations-on-change">
|
|
<h2>Running Operations On Change<a class="headerlink" href="#running-operations-on-change" title="Permalink to this headline">¶</a></h2>
|
|
<p>As we’ve mentioned, nearly all modules are written to be ‘idempotent’ and can relay when
|
|
they have made a change on the remote system. Playbooks recognize this and
|
|
have a basic event system that can be used to respond to change.</p>
|
|
<p>These ‘notify’ actions are triggered at the end of each ‘play’ in a playbook, and
|
|
trigger only once each. For instance, multiple resources may indicate
|
|
that apache needs to be restarted, but apache will only be bounced once.</p>
|
|
<p>Here’s an example of restarting two services when the contents of a file
|
|
change, but only if the file changes:</p>
|
|
<div class="highlight-python"><pre>- name: template configuration file
|
|
action: template src=template.j2 dest=/etc/foo.conf
|
|
notify:
|
|
- restart memcached
|
|
- restart apache</pre>
|
|
</div>
|
|
<p>The things listed in the ‘notify’ section of a task are called
|
|
handlers.</p>
|
|
<p>Handlers are lists of tasks, not really any different from regular
|
|
tasks, that are referenced by name. Handlers are what notifiers
|
|
notify. If nothing notifies a handler, it will not run. Regardless
|
|
of how many things notify a handler, it will run only once, after all
|
|
of the tasks complete in a particular play.</p>
|
|
<p>Here’s an example handlers section:</p>
|
|
<div class="highlight-python"><pre>handlers:
|
|
- name: restart memcached
|
|
action: service name=memcached state=restarted
|
|
- name: restart apache
|
|
action: service name=apache state=restarted</pre>
|
|
</div>
|
|
<p>Handlers are best used to restart services and trigger reboots. You probably
|
|
won’t need them for much else.</p>
|
|
<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">Notify handlers are always run in the order written.</p>

<h2>Include Files And Reuse<a class="headerlink" href="#include-files-and-reuse" title="Permalink to this headline">¶</a></h2>
|
|
<p>Suppose you want to reuse lists of tasks between plays or playbooks. You can use
|
|
include files to do this.</p>
|
|
<p>An include file simply contains a flat list of tasks, like so:</p>
|
|
<div class="highlight-python"><pre>---
|
|
# possibly saved as tasks/foo.yml
|
|
- name: placeholder foo
|
|
action: command /bin/foo
|
|
- name: placeholder bar
|
|
action: command /bin/bar</pre>
|
|
</div>
|
|
<p>Include directives look like this:</p>
|
|
<div class="highlight-python"><pre>- tasks:
|
|
- include: tasks/foo.yml</pre>
|
|
</div>
|
|
<p>You can also pass variables into includes directly. We might call this a ‘parameterized include’.</p>
|
|
<p>For instance, if deploying multiple wordpress instances, I could
|
|
contain all of my wordpress tasks in a single wordpress.yml file, and use it like so:</p>
|
|
<div class="highlight-python"><pre>- tasks:
|
|
- include: wordpress.yml user=timmy
|
|
- include: wordpress.yml user=alice
|
|
- include: wordpress.yml user=bob</pre>
|
|
</div>
|
|
<p>Variables passed in can be used in the included files. You can reference them like this:</p>
|
|
<div class="highlight-python"><pre>$user</pre>
|
|
</div>
|
|
<p>In addition to the explicitly passed in parameters, all variables from
|
|
the vars section are also available for use here as well.</p>
|
|
<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">Include statements are only usable from the top level
|
|
playbook file. This means includes can not include other
|
|
includes. This may be implemented in a later release.</p>
|
|
</div>
|
|
<p>Includes can also be used in the ‘handlers’ section, for instance, if you
|
|
want to define how to restart apache, you only have to do that once for all
|
|
of your playbooks. You might make a handlers.yml that looks like:</p>
|
|
<div class="highlight-python"><pre>----
|
|
# this might be in a file like handlers/handlers.yml
|
|
- name: restart apache
|
|
action: service name=apache state=restarted</pre>
|
|
</div>
|
|
<p>And in your main playbook file, just include it like so, at the bottom
|
|
of a play:</p>
|
|
<div class="highlight-python"><pre>handlers:
|
|
- include: handlers/handlers.yml</pre>
|
|
</div>
|
|
<p>You can mix in includes along with your regular non-included tasks and handlers.</p>
|
|
<p>Note that you can not conditionally path the location to an include file, like you can
|
|
with ‘vars_files’. If you find yourself needing to do this, consider how you can
|
|
restructure your playbook to be more class/role oriented.</p>

|
|
<p>Now that you’ve learned playbook syntax, how do you run a playbook? It’s simple.
|
|
Let’s run a playbook using a parallelism level of 10:</p>
|
|
<div class="highlight-python"><pre>ansible-playbook playbook.yml -f 10</pre>
|
|
</div>
|
|
</div>
|
|
<div class="section" id="tips-and-tricks">
|
|
<h2>Tips and Tricks<a class="headerlink" href="#tips-and-tricks" title="Permalink to this headline">¶</a></h2>
|
|
<p>Look at the bottom of the playbook execution for a summary of the nodes that were executed
|
|
and how they performed. General failures and fatal “unreachable” communication attempts are
|
|
kept seperate in the counts.</p>
|
|
<p>If you ever want to see detailed output from successful modules as well as unsuccessful ones,
|
|
use the ‘–verbose’ flag. This is available in Ansible 0.5 and later.</p>
|
|
<p>Also, in version 0.5 and later, Ansible playbook output is vastly upgraded if the cowsay
|
|
package is installed. Try it!</p>
