ironic.drivers.modules.ipxe module¶

iPXE Boot Interface

class ironic.drivers.modules.ipxe.iPXEBoot[source]¶

Bases: ironic.drivers.modules.pxe_base.PXEBaseMixin, ironic.drivers.base.BootInterface

capabilities = ['iscsi_volume_boot', 'ramdisk_boot', 'ipxe_boot']¶

clean_up_instance(**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

prepare_instance(**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(**kwargs)[source]¶

Prepares the boot of Ironic ramdisk using PXE.

This method prepares the boot of the deploy or rescue 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(**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.
