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.
We are going to use Ansible to update Horizon settings. Make sure that you have access to your openstack-ansible
deployment host.
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:
/etc/openstack_deploy/user_variables.yml
file to add the following line:horizon_keystone_multidomain_support: True
openstack-ansible
command:openstack-ansible /opt/openstack-ansible/playbooks/os-horizon-install.yml
The openstack-ansible
command produces a lot of output. For brevity, its output has been omitted.
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.
