  • neutron_db_pass – the password of neutron database user
Returns:

None
create_service_credentials(*args, **kwargs)

create the neutron service credentials

Parameters:

install_self_service(*args, **kwargs)

Install neutron for self-service

Parameters:
  • connection – The SQLAlchemy connection string to use to connect to the database. (string value) e.g. mysql+pymysql://neutron:NEUTRON_PASS@CONTROLLER_VIP/neutron
  • rabbit_hosts – RabbitMQ HA cluster host:port pairs. (list value) e.g. CONTROLLER1,CONTROLLER2
  • rabbit_user – The RabbitMQ userid. (string value) e.g. openstack
  • rabbit_pass – The RabbitMQ password. (string value)
  • auth_uri – Complete public Identity API endpoint. (string value) e.g. http://CONTROLLER_VIP:5000
  • auth_url – keystone admin endpoint e.g. http://CONTROLLER_VIP:35357
  • neutron_pass – the password of neutron user
  • nova_url – URL for connection to nova (Only supports one nova region currently) e.g. http://CONTROLLER_VIP:8774/v2.1
  • nova_pass – passowrd of nova user
  • public_interface – public interface e.g. eth1
  • local_ip – underlying physical network interface that handles overlay networks(uses the management interface IP) (ip address value)
  • nova_metadata_ip – IP address used by Nova metadata server. (string value) e.g. CONTROLLER_VIP
  • metadata_proxy_shared_secret – When proxying metadata requests, Neutron signs the Instance-ID header with a shared secret to prevent spoofing. You may select any string for a secret, but it must match here and in the configuration used by the Nova Metadata Server. NOTE: Nova uses the same config key, but in [neutron] section. (string value)
  • memcached_servers – Optionally specify a list of memcached server(s) to use for caching. (list value) e.g. CONTROLLER1:11211,CONTROLLER2:11211
  • populate – populate the neutron database
Returns:

None
