PXE Boot Interface
-
class
ironic.drivers.modules.pxe.PXEBoot[source]¶ Bases:
ironic.drivers.base.BootInterface-
clean_up_instance(*args, **kwargs)[source]¶ Cleans up the boot of instance.
This method cleans up the environment that was setup for booting the instance. It unlinks the instance kernel/ramdisk in node’s directory in tftproot and removes the PXE config.
Parameters: task – a task from TaskManager. Returns: None
-
clean_up_ramdisk(*args, **kwargs)[source]¶ Cleans up the boot of ironic ramdisk.
This method cleans up the PXE environment that was setup for booting the deploy ramdisk. It unlinks the deploy kernel/ramdisk in the node’s directory in tftproot and removes it’s PXE config.
Parameters: task – a task from TaskManager. Returns: None
-
get_properties()[source]¶ Return the properties of the interface.
Returns: dictionary of <property name>:<property description> entries.
-
prepare_instance(*args, **kwargs)[source]¶ Prepares the boot of instance.
This method prepares the boot of the instance after reading relevant information from the node’s instance_info. In case of netboot, it updates the dhcp entries and switches the PXE config. In case of localboot, it cleans up the PXE config.
Parameters: task – a task from TaskManager. Returns: None
-
prepare_ramdisk(*args, **kwargs)[source]¶ Prepares the boot of Ironic ramdisk using PXE.
This method prepares the boot of the deploy kernel/ramdisk after reading relevant information from the node’s driver_info and instance_info.
Parameters: - task – a task from TaskManager.
- ramdisk_params – the parameters to be passed to the ramdisk. pxe driver passes these parameters as kernel command-line arguments.
Returns: None
Raises: MissingParameterValue, if some information is missing in node’s driver_info or instance_info.
Raises: InvalidParameterValue, if some information provided is invalid.
Raises: IronicException, if some power or set boot boot device operation failed on the node.
-
validate(*args, **kwargs)[source]¶ Validate the PXE-specific info for booting deploy/instance images.
This method validates the PXE-specific info for booting the ramdisk and instance on the node. If invalid, raises an exception; otherwise returns None.
Parameters: task – a task from TaskManager. Returns: None Raises: InvalidParameterValue, if some parameters are invalid. Raises: MissingParameterValue, if some required parameters are missing.
