The Image management as a core portion ensures the integrality Of OpenStack. This paper combines research background with the open source project OpenStack, the main research contents are as follows: First,analysis of the interface of OpenStack and horizon code. There Paper describes the interface of the core subprojects Glance, Swift and Cinder ,then analyzes the horizon source code and Django Framework. With understanding of the interface and web framework, we can do more research to the image management of OpenStack. Second,the realization of image management. Try to Integrate Ceph as the back-end storage of image management and volumes, make image and instance a variety of storage management.In this paper, we use the Ceph to replace the original object storage Swift which provides image storage and use Ceph as the backend of Cinder block storage volume implementation.
