The default for sensor data collection is to only collect data for machines that are deployed, however operators may desire to know if there are failures in hardware that is not presently in use. When set to true, the conductor will collect sensor information from all nodes when sensor data collection is enabled via the send_sensor_data setting.

When conductors join or leave the cluster, existing conductors may need to update any persistent local state as nodes are moved around the cluster.

automated_clean
Type

boolean

Automated cleaning is a configurable set of steps, such as erasing disk drives, that are performed on the node to ensure it is in a baseline state and ready to be deployed to. This is done after instance deletion as well as during the transition from a “manageable” to “available” state. When enabled, the particular steps performed to clean a node depend on which driver that node is managed by; see the individual driver’s documentation for details. NOTE: The introduction of the cleaning operation causes instance deletion to take significantly longer. In an environment where all tenants are trusted (eg, because there is only one tenant), this option could be safely disabled.

allow_provisioning_in_maintenance
Type

Moving it from maintenance will make the process continue.

clean_callback_timeout

Finally the name of a binding method that must be present in tokens.

service_token_roles

list

Default

service

A choice of roles that must be present in a service token. Service tokens are allowed to request that an expired token can be used and so this check should tightly control that only actual services should be sending this token. Roles here are applied as an ANY check so any role in this list must be present. For backwards compatibility reasons this currently only affects the allow_expired check.
