Allowed Domains
===============
List Allowed Domains
--------------------
You can list all allowed domains using a load balancer service object.
An instance of ``OpenCloud\Common\Collection\PaginatedIterator`` is
returned.
.. code-block:: php
$allowedDomains = $service->allowedDomainList();
foreach ($allowedDomains as $allowedDomain) {
/** @var $allowedDomain OpenCloud\LoadBalancer\Resource\AllowedDomain **/
}
Access Lists
============
Access Lists allow fine-grained network access to a load balancer's VIP. Using
access lists, network traffic to a load balancer's VIP can be allowed or denied
from a single IP address, multiple IP addresses or entire network subnets.
Note that ``ALLOW`` network items will take precedence over ``DENY`` network
items in an access list.
To reject traffic from all network items except those with the ``ALLOW``
type, add a ``DENY`` network item with the address of ``0.0.0.0/0``.
.. include:: lb-setup.sample.rst
View Access List
----------------
You can view a load balancer's access list:
.. code-block:: php
$accessList = $loadBalancer->accessList();
foreach ($accessList as $networkItem) {
/** @var $networkItem OpenCloud\LoadBalancer\Resource\Access **/
}
Add Network Items To Access List
--------------------------------
You can add network items to a load balancer's access list very easily:
.. code-block:: php
$loadBalancer->createAccessList(array(
(object) array(
'type' => 'ALLOW',
'address' => '206.160.165.1/24'
),
(object) array(
'type' => 'DENY',
'address' => '0.0.0.0/0'
)
));
In the above example, we allowed access for 1 IP address, and used the
"0.0.0.0" wildcard to blacklist all other traffic.
Get the executable PHP scripts for this example:
* `Blacklist IP range <https://raw.githubusercontent.com/rackspace/php-opencloud/master/samples/LoadBalancer/blacklist-ip-range.php>`_
* `Limit access to 1 IP <https://raw.githubusercontent.com/rackspace/php-opencloud/master/samples/LoadBalancer/limit-access-to-1-ip.php>`_
Remove Network Item From Access List
------------------------------------
You an remove a network item from a load balancer's access list:
.. code-block:: php
$networkItem->delete();
