In this tutorial, we will study how to add a VM image to the Openstack Glance image service. I assume you already have a running Openstack setup and the glance service is running on the controller node.

What is Openstack Image Service?

The Openstack overview enables users to discover, register and retrieve virtual machine images.The default storage location for these images is /var/lib/glance/images/ The back end is a file.

Openstack Image Service also provides a REST API, which allows you to query the virtual machine image metadata and retrieve the actual image. You can store virtual machine images provided through the Image service in various locations from simple file systems to object storage systems (such as OpenStack Object Storage).

Get Glance pictures?

The easiest way to obtain a virtual machine image compatible with OpenStack is to download an image that someone else has created. Most images include the cloud-init package to support SSH key pair and user data injection.

I will show you how to add images to various operating systems by downloading work that others have already done. Of course, you can create your own images, but it is faster to get ready-made images.

The following is the default login user name for the instance created from the image added soon.

Debian: debian
Fedora: fedora
Ubuntu: ubuntu
RHEL: cloud-user
CentOS: centos
coreos: core
Arch Linux: arch
Gentoo: gentoo
OpenSUSE: root
Fedora CoreOS: core
Cirros:
    username: cirros
    Password: cubswin:)

Set image options

Now, set all images to Publicly visible And protect them fromDeleted accidentally.

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 by going to Horizon Dashboard Project>Calculation>Image. You should note that the “Protected” flag for all images is set to “Yes” and the “Visibility” is also set to “Public”.
