Use OpenStack with Zend Framework 2

OpenStack is becoming the open source standard for cloud computing. Most of the cloud vendors use OpenStack and the community of users is growing every day. In this talk we will give a brief introduction to OpenStack and we will present the new library service for Zend Framework 2 that supports the last version of the OpenStack API. You will see how is easy to use the OpenStack API with ZF2 thanks to a friendly object oriented interface.
This talk has been presented at ZendCon 2013 in Santa Clara (California).

1. Use OpenStack with Zend Framework 2 Enrico Zimuel Zend Framework Team Zend Technologies Inc.
2. 2 About me • Enrico Zimuel (@ezimuel) • Software Engineer since 1996 • PHP Engineer at Zend Technologies in the Zend Framework and Apigility Team • International speaker, author of books and technical articles • I was a Researcher programmer at Informatics Institute of University of Amsterdam • Co-founder of PUG Torino (Italy)
4. OpenStack • OpenStack is an open source cloud computing platform for public and private clouds • The goal is to enable any organization to create and offer cloud computing services running on standard hardware • Founded by Rackspace Hosting and NASA • http://www.openstack.org/
5. 5 OpenStack architecture Image source: http://www.openstack.org/software/
6. OpenStack dashboard (Grizzly)
7. OpenStack API • Identity Service (v. 2, 3) • Compute and Extensions (v. 2) • Image Service (v. 1, 2) • Block Storage Service (v. 2) • Networking (v. 2) • Object Storage (v. 1) • Orchestration (v. 1)
8. Some vendors using OpenStack
9. Do you want to try OpenStack? • http://www.trystack.org • A set up of clusters running OpenStack on both x86 and ARM architectures • It's totally free for you to try & test your apps
10. ZendService\OpenStack
11. 11 Status of the project • ZendService\OpenStack is a PHP library to use the API of OpenStack in a OO fashion way • The project started in Feb 2013 • It's 100% compatible with the API specifications of OpenStack • It uses the ZendService\Api component to interact with the HTTP API call https://github.com/zendframework/ZendService_Api
12. 12 Specification • Right now we support the following API: – BlockStorage – Compute – Identity – ObjectStorage • We are going to release these others soon: – Networking – Image
13. 13 Installation • Using composer: "require": { "zendframework/zendservice­openstack": "dev­master" } • Or from github (download or fork) https://github.com/zendframework/ZendService_OpenStack – curl ­s https://getcomposer.org/installer | php – php composer.phar install
14. Class structure • ZendService\OpenStack – AbstractOpenStack – Identity – BlockStorage – ObjectStorage – Compute – Networking – Image
15. Identity API – Auth and Token • authenticate($name, $password, $tenantName = null) • autenticateByKey($name, $key) • validateToken($token, $belongsTo = null) • checkToken($token, $belongsTo = null) • listEndpointsToken($token, $belongsTo = null)
16. 16 Identity API – User and Tenant • listUsers() • addUser(array $user) • updateUser(array $user) • deleteUser($id) • listGlobalRoles($id, $serviceId = null) • addTenant(array $tenant) • updateTenant(array $tenant) • deleteTenant($id)
17. Example: authentication
18. Example: user management
19. ObjectStorage API - containers • listContainers(array $options = array()) • createContainer($name, $metadata = array()) • deleteContainer($name) • getContainerMetadata($container) • setContainerMetadata($container, array $metadata) • deleteContainerMetadata($container, array $metadata)
20. ObjectStorage API - objects • listObjects($container, $options= array()) • getObject($container, $object) • setObject($container, $object, $content, $metadata = array(), $expire = null) • deleteObject($container, $object) • copyObject($containerFrom, $objectFrom, $containerTo, $objectTo) • setObjectMetadata($container, $object, array $metadata) • getObjectMetadata($container, $object)
21. Example – container and object
22. Example – metadata
23. Compute API - servers • listServers(array $options = array(), $details = false) • createServer(array $options) • getServer($id) • updateServer($id, array $options) • deleteServer($id) • listAddresses($id) • listAddressesByNetwork($id, $network)
24. Compute API – server actions • changeAdminPass($id, $password) • rebootServer($id, $soft = true) • rebuildServer($id, array $options) • resizeServer($id, $flavorRef) • confirmResizeServer($id) • revertResizeServer($id)
25. Compute API – flavor and image • createImage($id, array $options) • listFlavors(array $options = array(), $details = false) • getFlavor($id) • listImages(array $options = array(), $details = false) • getImage($id) • deleteImage($id)
26. Compute API – metadata • listServerMetadata($id) • listImageMetadata($id) • setServerMetadata($id, array $metadata) • setImageMetadata($id, array $metadata) • updateServerMetadata($id, array $metadata) • updateImageMetadata($id, array $metadata) • getServerMetadataItem($id, $key) • getImageMetadataItem($id, $key) • setServerMetadataItem($id, $key, $value = '') • setImageMetadataItem($id, $key, $value = '') • deleteServerMetadataItem($id, $key) • deleteImageMetadataItem($id, $key)
27. Example: create a server
28. Example: list existing servers
29. 29 Under the hood • We use ZendService\Api library to consume the OpenStack API • Simple PHP configuration file to build HTTP request. For instance: https://github.com/zendframework/ZendService_OpenSta ck/blob/master/library/ZendService/OpenStack/api/ide ntity/authenticate.php
30. 30 Future works • Complete the Networking and Image services • Support API versioning (?) • Documentation! Do you want to contribute? Fork the project on github and contact me!
