Registering a remotely stored image – OpenStack Cloud

Register the Remotely Stored Image

Images are predominantly standard installation media such as ISO images. Several pre-made images exist and can easily be imported into the Image service.
The OpenStack Image Service (also termed as Glance) provides a mechanism to remotely add an image that is stored at an externally accessible location. It allows you to register, discover and retrieve virtual machine images for use in our OpenStack environment. This allows for a convenient method of adding images we might want to use for our private cloud that have been uploaded to an external third-party server.

Getting started

To begin with, ensure that you are logged into our Ubuntu client, where we can run the glance tool. This can be installed using the following command:

sudo apt-get update
sudo apt-get -y install glance-client

Ensure that you have your environment variable set up correctly using ‘admin’ user and password, which has been created in the previous chapter as follows:

export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=
export OS_NO_CACHE=1

How to Store an Image into OpenStack Image Service 

Carry out the following steps to remotely store an image into our OpenStack Image Service:

1. To register a remote virtual image into our environment, we add a location parameter instead of streaming the image through a pipe on our glance command line:
glance image-create
–name=’Ubuntu 12.04 x86_64 Server’
–location https://webserver/precise-server-   cloudimg-amd64- disk1.img

2. This returns information similar to the following which is then stored in our OpenStack Image Service:

How it works

Usage of glance tool for specifying remote images directly provides a quick and convenient way to add images to our OpenStack Image Service repository. This happens with the location parameter which we add in our usual meta information to accompany this, as we would generally do with a locally specified image.
