<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"
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"</pre>
</div>
<p>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 &#8216;facter&#8217; and &#8216;ohai&#8217; prefixes for each.</p>
</div>
<div class="section" id="examples-3-deploying-from-source-control">
<h2>Examples 3: Deploying From Source Control<a class="headerlink" href="#examples-3-deploying-from-source-control" title="Permalink to this headline"></a></h2>
<p>Deploy your webapp straight from git:</p>
<div class="highlight-python"><pre>ansible webservers -m git -a "repo=git://foo dest=/srv/myapp version=HEAD"</pre>
</div>
<p>Since ansible modules can notify change handlers (see &#8216;Playbooks&#8217;) 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.</p>
