Configuring ironic-conductor service ------------------------------------ #. Replace ``HOST_IP`` with IP of the conductor host. .. code-block:: ini [DEFAULT] # IP address of this host. If unset, will determine the IP # programmatically. If unable to do so, will use "127.0.0.1". # (string value) my_ip=HOST_IP .. note:: If a conductor host has multiple IPs, ``my_ip`` should be set to the IP which is on the same network as the bare metal nodes. #. Configure the ironic-api service URL. Replace ``IRONIC_API_IP`` with IP of ironic-api service as follows: .. code-block:: ini [conductor] # URL of Ironic API service. If not set ironic can get the # current value from the keystone service catalog. (string # value) api_url=http://IRONIC_API_IP:6385 #. Configure the location of the database. Ironic-conductor should use the same configuration as ironic-api. Replace ``IRONIC_DBPASSWORD`` with the password of your ``ironic`` user, and replace DB_IP with the IP address where the DB server is located: .. code-block:: ini [database] # The SQLAlchemy connection string to use to connect to the # database. (string value) connection=mysql+pymysql://ironic:IRONIC_DBPASSWORD@DB_IP/ironic?charset=utf8 #. Configure the ironic-conductor service to use the RabbitMQ message broker by setting the following option. Ironic-conductor should use the same configuration as ironic-api. Replace ``RPC_*`` with appropriate address details and credentials of RabbitMQ server: .. code-block:: ini [DEFAULT] # A URL representing the messaging driver to use and its full # configuration. (string value) transport_url = rabbit://RPC_USER:RPC_PASSWORD@RPC_HOST:RPC_PORT/ #. Configure the ironic-conductor service so that it can communicate with the Image service. Replace ``GLANCE_IP`` with the hostname or IP address of the Image service: .. code-block:: ini [glance] # Default glance hostname or IP address. (string value) glance_host=GLANCE_IP .. note:: Swift backend for the Image service must be installed and configured for ``agent_*`` drivers. Ceph Object Gateway (RADOS Gateway) is also supported as the Image service's backend (`radosgw support `_). #. Set the URL (replace ``NEUTRON_IP``) for connecting to the Networking service, to be the Networking service endpoint: .. code-block:: ini [neutron] # URL for connecting to neutron. (string value) url=http://NEUTRON_IP:9696 To configure the network for ironic-conductor service to perform node cleaning, see `CleaningNetworkSetup `_ from the Ironic deploy guide. #. Configure credentials for accessing other OpenStack services. In order to communicate with other OpenStack services, the Bare Metal service needs to use service users to authenticate to the OpenStack Identity service when making requests to other services. These users' credentials have to be configured in each configuration file section related to the corresponding service: * ``[neutron]`` - to access the OpenStack Networking service * ``[glance]`` - to access the OpenStack Image service * ``[swift]`` - to access the OpenStack Object Storage service * ``[inspector]`` - to access the OpenStack Bare Metal Introspection service * ``[service_catalog]`` - a special section holding credentials the Bare Metal service will use to discover its own API URL endpoint as registered in the OpenStack Identity service catalog. For simplicity, you can use the same service user for all services. For backward compatibility, this should be the same user configured in the ``[keystone_authtoken]`` section for the ironic-api service (see "Configuring ironic-api service"). However, this is not necessary, and you can create and configure separate service users for each service. Under the hood, Bare Metal service uses ``keystoneauth`` library together with ``Authentication plugin`` and ``Session`` concepts provided by it to instantiate service clients. Please refer to `Keystoneauth documentation`_ for supported plugins, their available options as well as Session-related options for authentication and connection respectively. In the example below, authentication information for user to access the OpenStack Networking service is configured to use: * HTTPS connection with specific CA SSL certificate when making requests * the same service user as configured for ironic-api service * dynamic ``password`` authentication plugin that will discover appropriate version of Identity service API based on other provided options - replace ``IDENTITY_IP`` with the IP of the Identity server, and replace ``IRONIC_PASSWORD`` with the password you chose for the ``ironic`` user in the Identity service .. code-block:: ini [neutron] # Authentication type to load (string value) auth_type = password # Authentication URL (string value) auth_url=https://IDENTITY_IP:5000/ # Username (string value) username=ironic # User's password (string value) password=IRONIC_PASSWORD # Project name to scope to (string value) project_name=service # Domain ID containing project (string value) project_domain_id=default # User's domain id (string value) user_domain_id=default # PEM encoded Certificate Authority to use when verifying # HTTPs connections. (string value) cafile=/opt/stack/data/ca-bundle.pem #. Configure enabled drivers and hardware types as described in :doc:`/install/enabling-drivers`. #. Restart the ironic-conductor service: .. TODO(mmitchell): Split this based on operating system .. code-block:: console Fedora/RHEL7/CentOS7/SUSE: sudo systemctl restart openstack-ironic-conductor Ubuntu: sudo service ironic-conductor restart .. _Keystoneauth documentation: http://docs.openstack.org/developer/keystoneauth/
