-
class
ironic.drivers.modules.ansible.deploy.
AnsibleDeploy
[source]¶ Bases:
ironic.drivers.modules.agent_base_vendor.HeartbeatMixin
,ironic.drivers.base.DeployInterface
Interface for deploy-related actions.
-
continue_deploy
(task)[source]¶ Continues the deployment of baremetal node.
This method continues the deployment of the baremetal node after the ramdisk have been booted.
- Parameters
task – a TaskManager instance
-
execute_clean_step
(task, step)[source]¶ Execute a clean step.
- Parameters
task – a TaskManager object containing the node
step – a clean step dictionary to execute
- Returns
None
-
get_clean_steps
(task)[source]¶ Get the list of clean steps from the file.
- Parameters
task – a TaskManager object containing the node
- Returns
A list of clean step dictionaries
-
prepare_cleaning
(task)[source]¶ Boot into the ramdisk to prepare for cleaning.
- Parameters
task – a TaskManager object containing the node
- Raises
NodeCleaningFailure – if the previous cleaning ports cannot be removed or if new cleaning ports cannot be created
- Returns
None or states.CLEANWAIT for async prepare.
-
reboot_to_instance
(task)[source]¶ Method invoked after the deployment is completed.
- Parameters
task – a TaskManager instance
-
take_over
(task)[source]¶ Take over management of this task’s node from a dead conductor.
If conductors’ hosts maintain a static relationship to nodes, this method should be implemented by the driver to allow conductors to perform the necessary work during the remapping of nodes to conductors when a conductor joins or leaves the cluster.
- For example, the PXE driver has an external dependency:
Neutron must forward DHCP BOOT requests to a conductor which has prepared the tftpboot environment for the given node. When a conductor goes offline, another conductor must change this setting in Neutron as part of remapping that node’s control to itself. This is performed within the takeover method.
- Parameters
task – A TaskManager instance containing the node to act on.
-
tear_down_cleaning
(task)[source]¶ Clean up the PXE and DHCP files after cleaning.
- Parameters
task – a TaskManager object containing the node
- Raises
NodeCleaningFailure – if the cleaning ports cannot be removed
-
