OpenStack concepts ✤ virtual infrastructure services ✤ accessed via HTTP
(RESTful) API ✤ developed by an open-source community ✤ highly configurable
OpenStack governance ✤ Independent foundation ✤ Board of Directors: some
directors appointed by funding companies, others elected at-large ✤ Technical Committee: elected by active members ✤ Biannual releases and summit/workshops ✤ Project Technical Leaders
OpenStack APIs ✤ Native REST ✤ EC2-compatible ✤ Internal (python)
Compute ✤ Project “Nova” ✤ Supports multiple hypervisors including KVM,
Xen ✤ Massively-scalable architecture ✤ Working towards interoperable workloads
Storage ✤ Project “Swift” ✤ Elastic “blob” storage ✤ Can
scale to regional or even global deployments ✤ Eventually consistent
Networking ✤ Project “Neutron” (formerly “Quantum”) ✤ Dynamically create and
manage L2/L3 networks ✤ Works with plugins for virtual network devices (OpenVSwitch, others)
Dashboard ✤ Project “Horizon” ✤ Clean, simple user interface ✤
Uses native API to communicate to services
Shared Services ✤ Identity—“Keystone” ✤ Image—“Glance” ✤ Telemetry—“Ceilometer” ✤ Orchestration—“Heat”
Other Projects ✤ OpenStack-SDKs ✤ Savanna—Hadoop provisioning ✤ Trove—Database ✤
Bare metal—Ironic ✤ Queue—Marconi
How to interact with OpenStack ✤ Control panel ✤ Command
line client ✤ cURL ✤ SDK
First Q&A
Resources ✤ http://github.com/rackspace/php-opencloud ✤ http://developer.rackspace.com/ ✤ http://docs.openstack.org/
Installing php-opencloud # Install Composer curl -sS https://getcomposer.org/installer | php
# Require php-opencloud as a dependency php composer.phar require rackspace/php- opencloud:dev-master
Example 1. Create a server
1.1 Authentication <?php require 'vendor/autoload.php'; use OpenCloud\Rackspace; print "Creating client...\n";
$client = new Rackspace(Rackspace::US_IDENTITY_ENDPOINT, array( 'username' => getenv('OS_USERNAME'), 'apiKey' => getenv('NOVA_API_KEY'), 'tenantName' => getenv('OS_TENANT_NAME') ));
1.2 Attach print "Attaching to compute...\n"; try { $compute =
$client->computeService( 'cloudServersOpenStack', 'IAD'); } catch (\Guzzle\Http\Exception\BadResponseException $e) { echo $e->getResponse(); die("OOPS\n"); }
1.3 Image print "Getting an image...\n"; $centos = $compute->image('85019bd8-fb5d-4230-b3bc-63b192800f28');
1.4 Flavor print "Getting a flavor...\n"; $flavor = $compute->flavor('performance1-1');
1.5 Create print "Creating a server...\n"; use OpenCloud\Compute\Constants\Network; $server =
$compute->server(); try { $response = $server->create(array( 'name' => 'My lovely server', 'image' => $centos, 'flavor' => $flavor, 'networks' => array( $compute->network(Network::RAX_PUBLIC), $compute->network(Network::RAX_PRIVATE) ) ));
1.6 Exception Handling } catch (\Guzzle\Http\Exception\BadResponseException $e) { // No!
Something failed. Let's find out: $responseBody = (string) $e->getResponse()->getBody(); $statusCode = $e->getResponse()->getStatusCode(); $headers = $e->getResponse()->getHeaderLines(); echo sprintf("Status: %s\nBody: %s\nHeaders: %s", $statusCode, $responseBody, implode(', ', $headers)); }
1.7 Poll use OpenCloud\Compute\Constants\ServerState; $callback = function($server) { if (!empty($server->error))
{ var_dump($server->error); exit; } else { echo sprintf( "\rWaiting on %s/%-12s %4s%%", $server->name(), $server->status(), isset($server->progress) ? $server->progress : 0 ); } }; $server->waitFor(ServerState::ACTIVE, 600, $callback);
1.8 Let's try it out LIVE DEMO
Example 2. Listing flavors print "Attaching to compute...\n"; try {
$compute = $client->computeService( 'cloudServersOpenStack', getenv('OS_REGION_NAME')); } catch (\Guzzle\Http\Exception\BadResponseException $e) { echo $e->getResponse(); } $list = $compute->flavorList(true); foreach($list as $flavor) { printf("%20s %-20s\n", $flavor->id(), $flavor->name()); }
Example 3. File upload print "Attaching to object storage...\n"; try
{ $storage = $client->objectStoreService( 'cloudFiles', getenv('OS_REGION_NAME')); } catch (\Guzzle\Http\Exception\BadResponseException $e) { echo $e->getResponse(); die("OOPS\n"); }
3.1 create a container // create a container $container =
$storage->createContainer('MidWestPHP'); if ($container === false) $container = $storage-
3.2 upload a file // create an object (empty) print
"Creating an object...\n"; use OpenCloud\ObjectStore\Resource\DataObject; $container->uploadObject('myfile', fopen('upload_file.php', 'r+'));
3.3 list objects // list objects print "Listing objects:\n"; $files
= $container->objectList(); while ($file = $files->next()) { printf("* %s (%d)\n.", $file->getName(), $file->getContentLength()); }
