Incompatible Changes

We're sorry, but this release comes with some incompatible changes. The most changes won't effect the majority of users, but we needed to change those things to fix some nasty things and to be more flexible in the future.


With Rex::Test it is possible to test your Rexfile on a local VM before executing the code on your servers. Rex::Test uses Rex::Box to create the VM, but currently it only supports VirtualBox VMs.

To create a test just create a new file inside a t directory: t/base.t.

use Rex::Test::Base;
use Data::Dumper;
use Rex -base;

test {
    my $t = shift;

    $t->name("ubuntu test");

    $t->vm_auth( user => "root", password => "box" );


    $t->has_content( "/etc/passwd", qr{root:x:0:}ms );

    run "ls -l";
    $t->ok( $? == 0, "ls -l returns success." );




Create clean development environments for your projects. Test your software in a production like environment.

With Rex/Boxes you can easily create your test environment with VirtualBox. You can use prebuild VM Images or roll your own. Read the quickstart guide to create your own environment in minutes.

# # CALL: # rex init --name=gpw --url=http://domain.tld/ubuntu-server-12.10-amd64.qcow2 desc "Initialize and start the VM: rex init --name=vmname [--url=http://...]"; task "init", make { my $param = shift;
box {
    <span class="hljs-keyword">my</span> (<span class="hljs-type">$box</span>) = <span class="hljs-type">@_</span>;
    <span class="hljs-type">$box</span>-&gt;<span class="hljs-type">name</span>( <span class="hljs-type">$param</span>-&gt;{name} );

    <span class="hljs-comment"># where to download the base image</span><span class="hljs-comment">

$box->url( $param->{url} );

    <span class="hljs-comment"># default is nat</span><span class="hljs-comment">

$box->network( 1 => { type => "nat", }, 2 => { type => "bridged", bridge => "br1", } );

    <span class="hljs-comment"># define the authentication to the box</span><span class="hljs-comment">

# if you're downloading one from box.rexify.org this is the default. $box->auth( user => "root", password => "box", );

    <span class="hljs-comment"># if you want to provision the machine,</span><span class="hljs-comment">

# you can define the tasks to do that $box->setup(qw/install_webserver/); };



Changes in the Cloud API

my $instance = cloud_instance create => { image_id => "80fbcb55-b206-41f9-9bc2-2dd7aac6c061", name => "myvm01", flavor => "performance1-1", networks => ["a733f9d7-098e-4bf1-881d-5a91e84b44bb"]; # networks is optional };

cloud_volume attach => $vol_id, to => $instance->{id};

-   Terminating an instance and removing the volume.

    <pre><code class="hljs">cloud_service "<span class="hljs-string">RackSpace</span>";

cloud_instance terminate => $instance->{id}; cloud_volume delete => $vol_id;
