The OpenStack Dashboard gives us the ability to administer users through the web interface. This allows an administrator to easily create and edit users within an OpenStack environment. To manage users, you must log in using an account that is a member of the admin role.
Load a web browser, point it to our OpenStack Dashboard address at http://192.168.100.117/, and log in as a user in the default domain, such as the developer user, created in the Common OpenStack identity tasks recipe in Chapter 2, The OpenStack Client with the cookbook4 password. The URL for our dashboard is same as the public load balancer IP as discussed in Chapter 1, Installing OpenStack with Ansible. If you need to find out at what URL your Horizon is, use public IP from the OpenStack catalog list as described in Chapter 3, Keystone – OpenStack Identity Service.
User management under OpenStack Dashboard is achieved by carrying out the steps discussed in the following sections.
To add users, perform the following steps:
- In the Identity panel, click on the Users option to get a list of users configured on the system:
This screenshot truncates the available user list for the sake of clarity and space.
- To create a new user, click on the Create User button.
- We will be presented with a form that asks for username details. Enter the username, email, and the password for that user. In the example shown in the following screenshot, we create a user named
test, set a password, and assign that user to thehorizonproject with the role of admin. Click on the Create User button to create a new user with all the details specified:
- We will be returned to the screen listing the users of our OpenStack environment with a message stating that our user creation was successful.
To delete users, perform the following steps:
