Prerequisites

Before you install and configure the DNS service, you must create service credentials and API endpoints.

Source the admin credentials to gain access to admin-only CLI commands:
```
$ source admin-openrc
```

To create the service credentials, complete these steps:

Create the designate user:

$ openstack user create --domain default --password-prompt designate

Add the admin role to the designate user:

$ openstack role add --project service --user designate admin

Create the designate service entities:

$ openstack service create --name designate --description "DNS" dns

Create the DNS service API endpoint:

$ openstack endpoint create --region RegionOne \
  dns public http://controller:9001/
