Enabling domains in the OpenStack dashboard
If you are using multiple domains in your OpenStack environment, you will need to enable them in the OpenStack dashboard (Horizon) as well. To do so, the OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT variable in Horizon settings needs to be set to True. In this example, we will show you how to do so using OpenStack Ansible playbook.
Getting ready
We are going to use Ansible to update Horizon settings. Make sure that you have access to your openstack-ansible deployment host.
How to do it…
To enable multidomain support in the OpenStack dashboard, we will update one horizon variable, OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT in local_settings.py using the openstack-ansible deployment tool. First, you will need to connect to your openstack-ansible deployment host. Once connected, execute the following steps:
- Edit the
/etc/openstack_deploy/user_variables.ymlfile to add the following line:horizon_keystone_multidomain_support: True - Deploy Horizon with the
openstack-ansiblecommand:openstack-ansible /opt/openstack-ansible/playbooks/os-horizon-install.yml
The
openstack-ansiblecommand produces a lot of output. For brevity, its output has been omitted. - Launch the OpenStack dashboard to verify that the login screen now shows domain field:
How it works…
In OpenStack, if you are taking advantage of the multiple domain functionality, you have full control via command-line tools. However, if you want to be able to use the OpenStack dashboard with multiple domains, you will need to enable Horizon's multidomain support. To do so, you need to update the Horizon settings file. Since we are using the openstack-ansible tool, we updated the user_variables.yml file and ran the openstack-ansible command. This command updated the required variable and restarted the apache2 (HTTP server) services on the Horizon container.
