Adding images to Openstack Glance

August 12, 2017

In this tutorial we’re going to look at how to start adding images to Openstack Glance image service. I assume you already have a running Openstack setup, and glance service runs on the controller node. If you’re doing initial setup, look at

Openstack Liberty Lab Part Four: Configuring Glance Image Service

What is Openstack image service?

Openstack glance enables users to discover, register, and retrieve virtual machine images. The default location these images are stored is /var/lib/glance/images/ with its backend being a file.

Openstack image service also offers a REST API that enables you to query virtual machine image metadata and retrieve an actual image. You can store virtual machine images made available through the Image service in a variety of locations, from simple file systems to object-storage systems like OpenStack Object Storage.

Obtaining images?

The simplest way to obtain a virtual machine image that works with OpenStack is to download one that someone else has already created. Most of the images contain the cloud-init package to support the SSH key pair and user data injection. I’ll show you how to add images for various operating systems by downloading what other people already made. Of course you can create your own images, but it is faster to obtain ready made images.

Setting image options options

openstack image set  --help

Protect all images from being deleted

Now let’s set all images to be publicly visible and protect them from accidental deletion.

IMAGE_IDS=`openstack image list | egrep '[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}' -o`
for i in ${IMAGE_IDS[@]}; do
    openstack image set --public $i
    openstack image set --protected $i
done

Confirm from Horizon Dashboard by going to Project > Compute > Images. You should notice Protected flag is set to yes for all images and Visibility set to Public as well.
