Openstack Liberty Lab Part Four: Configuring Glance Image Service
Glance is image service which enables users to discover, register, and retrieve virtual machine images.
I assume you installed glance openstack image service in Part one of this Lab series, if you didn’t, go back and do it first.The link can be found from what we’ve covered so far:
Openstack Liberty Lab PART ONE: Setup Networking and all Prerequisites
Openstack Liberty Lab PART TWO: Install Openstack Packages
Openstack Liberty Lab PART THREE: Configuring Keystone identity service
Steps for configuring Glance image service are:
- Add user and database required by glance service.
[root@controller ~]# mysql -u root -p
Enter password:

- Add glance user and assign user Admin role:
[root@controller ~]# openstack user create --domain default --project service --password moonstack glance

We’ve configured Glance image service successfully. In next tutorial, we’ll add images that Glance will store. We’ll create both CentOS and Ubuntu glance images manually.
