clean_up_instance
(task)[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
-
ipxe_enabled
= True¶
-
prepare_instance
(task)[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
(task, ramdisk_params)[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
(task)[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.
