ironic.drivers.modules.autodetect module

class ironic.drivers.modules.autodetect.AutodetectDeploy(*args, **kwargs)

Bases: DeployInterface

Deploy interface that auto-detects the appropriate deployment method.

clean_up(task)

Clean up the deployment environment for the task’s node.

Parameters:

task – A TaskManager instance containing the node to act on.

deploy(task)

Perform a deployment to the task’s node.

This method should not be called directly as the autodetect interface is expected to switch to a concrete interface during switch_interface(). If this is called, it means the interface switch did not happen.

Parameters:

task – A TaskManager instance containing the node to act on.

Raises:

InstanceDeployFailure if deployment fails.

get_properties()

Return the properties of the interface.

Returns:

dictionary of <property name>:<property description> entries.

prepare(task)

Prepare the deployment environment for the task’s node.

switch_interface(task)

Switch the interface to use for deployment.

This calls supports_deploy() methods of deploy interfaces configured in the ‘autodetect_deploy_interfaces’ option, in order, to determine which interface is supported for the current node/image. The first interface that returns True from supports_deploy() is chosen. If no interfaces are detected as supported, the last interface in the list is chosen as the fallback.

Raises:

InvalidParameterValue if the interface is not enabled.

Parameters:

task – A TaskManager instance containing the node to act on.

take_over(task)

Take over management of this task’s node from a dead conductor.

Parameters:

task – A TaskManager instance containing the node to act on.

tear_down(task)

Tear down a previous deployment on the task’s node.

Parameters:

task – A TaskManager instance containing the node to act on.

Returns:

deploy state DELETED.

validate(task)

Validate the driver-specific Node deployment info.

This method creates the deploy interface that would be switched to and calls its validate() method.

Parameters:

task – A TaskManager instance containing the node to act on.

Raises:

MissingParameterValue if required parameters are missing.
