auth_url = http://controller:35357
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default

Finalize installation

systemctl enable openstack-glance-api.service openstack-glance-registry.service

systemctl start openstack-glance-api.service openstack-glance-registry.service

2.Verify operation(just for test)

. admin-openrc
yum install -y wget

wget http://download.cirros-cloud.net/0.3.4/cirros-0.3.4-x86_64-disk.img

openstack image create "cirros" --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public
