Image service
The OpenStack image service (codenamed Glance) provides a central repository for all virtual machine disk files and snapshots - when a virtual machine is created, the image file is pulled from the Glance repository.
Users and administrators can upload and share their own images in a variety of formats, including:
- VirtualBox image format
- VMWare image format
- QCOW2 format
- Docker containers
- Amazon AMI format
The following section will assist you with some of the basic functions of the Glance image service. For additional reading, please see the Glance documentation:
