Download pre-built images for OpenStack

You can run a number of different Linux distributions and operating systems on top of your RDO cloud. This is a collection of various OpenStack-ready images that you can use:

• Fedora cloud images
• RHEL 7 image (requires RHEL subscription)
• RHEL 6 image (requires RHEL subscription)
• CentOS 7 images
• CentOS 6 images
• Ubuntu cloud images
• Windows Server 2012 test image
• openSUSE cloud images
• Debian cloud images
• See also the oz-image-build list on Github
• The OpenStack Community App Catalog contains a large number of OpenStack-ready Glance images

Import images into Glance

You can load an image from the command line with Glance. For example:

$ curl -O https://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/fedora/linux/releases/23/Cloud/x86_64/Images/Fedora-Cloud-Base-23-20151030.x86_64.qcow2

$ glance --os-image-api-version 2 image-create --name 'Fedora-23-x86_64' --disk-format qcow2 --container-format bare --file Fedora-Cloud-Base-23-20151030.x86_64.qcow2

Alternatively, go to the Images and Snapshots tab in your OpenStack dashboard to add images via the GUI.

See the OpenStack documentation for more details about the Glance command-line tools.

Build your own images

• The OpenStack upstream has good guidance on various methods for building your own images: http://docs.openstack.org/image-guide/create-images-automatically.html
• See also Creating custom images for OpenStack
• A blog post on building a Windows image for OpenStack

The resulting image file can be imported into Glance similarly to any other image:

$ glance image-create --name F20-x86_64 --disk-format qcow2 --container-format bare --is-public True < fedora-image.qcow2
