Managing images with OpenStack Image Service

Uploading and managing images within OpenStack Storage is achieved using the glance command-line tool. This tool allows us to upload, remove, and change information about the stored images for use within our OpenStack environment.

Getting ready

To begin with, ensure that you are either logged in to an Ubuntu client where we can run the glance tool, or on our OpenStack Controller where OpenStack Image Service is running directly. If the Glance client isn't installed, this can be installed using the following commands:

sudo apt-get update
sudo apt-get install python-glanceclient

Ensure that you have your environment variables set up correctly with our admin user and password, as created in the previous chapter:

export OS_TENANT_NAME=cookbook
export OS_USERNAME=admin
export OS_PASSWORD=openstack
export OS_AUTH_URL=https://192.168.100.200:5000/v2.0/
export OS_NO_CACHE=1
export OS_KEY=/vagrant/cakey.pem
export OS_CACERT=/vagrant/ca.pem
