Mixin with deploy methods.
AgentDeployMixin.
configure_local_boot
(task, root_uuid=None, efi_system_part_uuid=None, prep_boot_part_uuid=None)¶Helper method to configure local boot on the node.
This method triggers bootloader installation on the node. On successful installation of bootloader, this method sets the node to boot from disk.
Parameters: |
|
---|---|
Raises: | InstanceDeployFailure if bootloader installation failed or on encountering error while setting the boot device on the node. |
AgentDeployMixin.
continue_cleaning
(task, **kwargs)¶Start the next cleaning step if the previous one is complete.
In order to avoid errors and make agent upgrades painless, the agent compares the version of all hardware managers at the start of the cleaning (the agent’s get_clean_steps() call) and before executing each clean step. If the version has changed between steps, the agent is unable to tell if an ordering change will cause a cleaning issue so it returns CLEAN_VERSION_MISMATCH. For automated cleaning, we restart the entire cleaning cycle. For manual cleaning, we don’t.
Additionally, if a clean_step includes the reboot_requested property set to True, this method will coordinate the reboot once the step is completed.
AgentDeployMixin.
prepare_instance_to_boot
(task, root_uuid, efi_sys_uuid, prep_boot_part_uuid=None)¶Prepares instance to boot.
Parameters: |
|
---|---|
Raises: | InvalidState if fails to prepare instance |
AgentDeployMixin.
reboot_and_finish_deploy
(task)¶Helper method to trigger reboot on the node and finish deploy.
This method initiates a reboot on the node. On success, it marks the deploy as complete. On failure, it logs the error and marks deploy as failure.
Parameters: | task – a TaskManager object containing the node |
---|---|
Raises: | InstanceDeployFailure, if node reboot failed. |
AgentDeployMixin.
refresh_clean_steps
(task)¶Refresh the node’s cached clean steps from the booted agent.
Gets the node’s clean steps from the booted agent and caches them. The steps are cached to make get_clean_steps() calls synchronous, and should be refreshed as soon as the agent boots to start cleaning or if cleaning is restarted because of a cleaning version mismatch.
Parameters: | task – a TaskManager instance |
---|---|
Raises: | NodeCleaningFailure if the agent returns invalid results |
