Creating OpenStack domains in Keystone
If you wish to use more than one domain for your OpenStack deployment, consider using separate domains. Think of domains as separate accounts or departments in large organizations. For this section, we will create a domain for our project, called bookstore.
Getting ready
Ensure that you are logged on to a correctly configured OpenStack client and can access the OpenStack environment as a user with admin privileges.
Refer to Chapter 2, The OpenStack Client, for details of setting up your environment to use OpenStack command-line client.
How to do it…
To create a domain in our OpenStack environment, perform the following step:
- We start by creating a domain called
bookstoreas follows:openstack domain create --description "Book domain" bookstoreThe output will look similar to this:
How it works…
In OpenStack, high level identity resources can be grouped under different domains. If you have to manage distinct organizations within your OpenStack environment, having separate domains for managing them might be very beneficial. By default, your OpenStack environment most likely has a default domain called "Default." By running the preceding command, we just created an additional domain that can used to manage resources related to this book. The syntax is as follows:
openstack domain create --description <description> <name>
The description parameter is also optional, but highly recommended. The domain name must be unique to other domains in the environment.
