How to create instances without volume by default?¶

1. In the Horizon configuration file /etc/openstack-dashboard/local_settings.py add the following:

   REST_API_REQUIRED_SETTINGS = [
   'CREATE_IMAGE_DEFAULTS',
   'DEFAULT_BOOT_SOURCE',
   'ENFORCE_PASSWORD_CHECK',
   'LAUNCH_INSTANCE_DEFAULTS',
   'OPENSTACK_HYPERVISOR_FEATURES',
   'OPENSTACK_IMAGE_FORMATS',
   'OPENSTACK_KEYSTONE_BACKEND',
   'OPENSTACK_KEYSTONE_DEFAULT_DOMAIN',
   ]
   LAUNCH_INSTANCE_DEFAULTS = {
   'create_volume': False,
   }
   

2. Recollect static and compress it with commands:

   python3 /usr/share/openstack-dashboard/manage.py collectstatic
   python3 /usr/share/openstack-dashboard/manage.py compress
   

3. Restart apache2 and memcached services:

   systemctl restart apache2
   systemctl restart memcached
