task "prepare", sub {
service apache2 => "ensure", "started";
service apache2 => "ensure", "stopped";
};

Added an iptables module to manage basic iptables rules.

task "firewall", sub {


# clear all rules
    iptables_clear;


# open port 22 on all devices
    open_port 22;


# open port 22 and 80 on eth0
    open_port [ 22, 80 ] => { dev => "eth0", };


# close all ports on all devices
    close_port "all";


# close port 22 on dev eth0
    close_port 22 => { dev => "eth0", };


# redirect port 80 to 10080
    redirect_port 80 => 10080;


# redirect port 80 to 10080 on eth0
    redirect_port 80 => {
    dev => "eth0",
    to  => 10080,
};


# set default state rules (RELATED,ESTABLISHED) to accept on all devices
    default_state_rule;


# set default state rules (RELATED,ESTABLISHED) to accept on eth0
    default_state_rule dev => "eth0";


# make the system a nat gateway for its default route
    # this will set the sysctl entry net.ipv4.ip_forward to 1, too.
    is_nat_gateway;


# define a custom iptables rule
    iptables t => "filter", A => "INPUT", i => "eth0", ...;
};

Added Amazon EC2 Support

use Data::Dumper;
use Rex::Commands::Cloud;

user "root"; public_key "/path/to/your/ec2-public.key"; private_key "/path/to/your/ec2-private.key.pem";

# set the cloud service provider to "Amazon" cloud_service "Amazon";

# set cloud auth cloud_auth "$access_key", "$secret_access_key";

# set cloud region cloud_region "ec2.eu-west-1.amazonaws.com";

# define a group with all running ec2 instances group ec2 => get_cloud_instances_as_group();

task "list", sub { print Dumper cloud_instances_list; print Dumper cloud_volume_list;

<span class="hljs-function">print</span> Dumper get_cloud_regions;
<span class="hljs-function">print</span> Dumper get_cloud_availability_zones;

};

task "create", sub {

<span class="hljs-comment"># if you want an ebs volume, create it. if not, you don't need this.</span><span class="hljs-comment">

my $vol_id = cloud_volume create => { size => 1, zone => "eu-west-1a"; };

<span class="hljs-comment"># create the cloud instances and attach the just created ebs volume.</span><span class="hljs-comment">

cloud_instance create => { image_id => "ami-02103876", name => "test-ec2", key => "my-test-key", volume => $vol_id, # if you don't have a volume, skip this zone => "eu-west-1a", # the volume and the instance must be in the same zone. skip this if you don't have a volume. }; };

task "destroy", sub { cloud_volume detach => "vol-xxaabb"; cloud_instance terminate => "i-ffgghhjj"; cloud_colume delete => "vol-xxaabb"; };
