OpenStack Caracal : Configure Neutron #22024/08/06 |
Configure OpenStack Network Service (Neutron).
This example is based on the environment like follows. Configure Neutron services with Open Virtual Network (OVN). eth0|10.0.0.30 +-----------+-----------+ | [ dlp.srv.world ] | | (Control Node) | | | | MariaDB RabbitMQ | | Memcached Nginx | | Keystone httpd | | Glance Nova API | | Nova Compute | | Neutron Server | | Open vSwitch | | OVN Metadata Agent | | OVN-Controller | +-----------------------+ |
