13 Python API #

Extract selected command name

Extract argument dict for selected command

Extract argument dict for global arguments

Extract service name from argument parse result

Loads task class plugin according to service and command name

Execute man to show the selected manual page

Execute a program and return an io file handle pair back. stdout and stderr are both on different channels. The caller must read from the output file handles in order to actually run the command. This can be done using the CommandIterator from command_process

Example:

process = Command.call(['ls', '-l'])

Execute a program and block the caller. The return value is a CommandT namedtuple containing the stdout, stderr and return code information. Unless raise_on_error is set to False an exception is thrown if the command exits with an error code not equal to zero. If raise_on_command_not_found is False and the command is not found, then None is returned.

Example:

result = Command.run(['ls', '-l'])

Return logging flags

Return currently used log level

Umount by the mountpoint directory

Wait up to 10sec trying to umount. If the resource stays busy the call will raise an exception unless raise_on_busy is set to False. In case the umount failed and raise_on_busy is set to False, the method returns False to indicate the error condition.

Umount by the mountpoint directory in lazy mode

Release the mount in any case, however the time when the mounted resource is released by the kernel depends on when the resource enters the non busy state

Check if we are effectively root on the system. If not an exception is thrown

When building wsl images there are some naming conventions that must be fulfilled to run the container on Microsoft Windows

If a kiwi initrd is used, a lookup to the specified boot description is done and fails early if it does not exist

If a kiwi initrd is used, the kernel used to build the kiwi initrd and the kernel used in the system image must be the same in order to avoid an inconsistent boot setup

When creating container images the specific tools are used in order to import and export OCI or Docker compatible images. This check searches for those tools to be installed in the build system and fails if it can’t find them

OEM images if configured to use dracut as initrd system requires the KIWI provided dracut-kiwi-oem-repart module to be installed at the time dracut is called. Thus this runtime check examines if the required package is part of the package list in the image description.

Disk images configured to use a root filesystem overlay requires the KIWI provided kiwi-overlay dracut module to be installed at the time dracut is called. Thus this runtime check examines if the required package is part of the package list in the image description.

Live ISO images uses a dracut initrd to boot and requires the KIWI provided kiwi-live dracut module to be installed at the time dracut is called. Thus this runtime check examines if the required package is part of the package list in the image description.

OEM images if configured to use dracut as initrd system and configured with one of the installiso, installstick or installpxe attributes requires the KIWI provided dracut-kiwi-oem-dump module to be installed at the time dracut is called. Thus this runtime check examines if the required package is part of the package list in the image description.

KIWI images which makes use of kiwi dracut modules has to use module versions compatible with the version of this KIWI builder code base. This is important to avoid inconsistencies between the way how kiwi includes its own dracut modules and former version of those dracut modules which could be no longer compatible with the builder. Therefore this runtime check maintains a min_version constraint for which we know this KIWI builder to be compatible with.

Verify that the efifatimagesize does not exceed the max El Torito load size of 65535 * 512 bytes

Disk images configured to use a root filesystem overlay only supports the standard EFI mode and not secure boot. That’s because the shim setup performs changes to the root filesystem which can not be applied during the bootloader setup at build time because at that point the root filesystem is a read-only squashfs source.

Verify that all repos marked with the imageinclude attribute can be resolved into a http based web URL

Verify that the selected image type is unique within the range of the configured types and profiles.

Kiwi requires a <version> element to be specified as part of at least one <preferences> section.

Raise for still included <include> statements as not resolvable. The KIWI XSLT processing replaces the specified include directive(s) with the given file reference(s). If this action did not happen for example on nested includes, it can happen that they stay in the document as sort of waste.

If the boot attribute is used without selecting kiwi as the initrd_system, the setting of the boot attribute will not have any effect. We assume that configurations which explicitly specify the boot attribute wants to use the custom kiwi initrd system and not dracut.

Options set via the luksformat element are passed along to the cryptsetup tool. Only options that are known to the tool should be allowed. Thus this runtime check looks up the provided option names if they exist in the cryptsetup version used on the build host

If the image description enables the mediacheck attribute the required tools to run this check must be installed on the image build host

The devicepersistency setting by-partuuid can only be used in combination with a partition table type that supports UUIDs. In any other case Linux creates artificial values for PTUUID and PARTUUID from the disk signature which can change without touching the actual partition table. We consider this unsafe and only allow the use of by-partuuid in combination with partition tables that actually supports it properly.

Verify that there are repositories configured

The optional oem-swapname is only effective if used together with the LVM volume manager. A name for the swap space can only be set if it is created as a LVM volume. In any other case the name does not apply to the system

The target directory must be outside of the kiwi shared cache directory in order to avoid busy mounts because kiwi bind mounts the cache directory into the image root tree to access host caching information

The optional volume label in a systemdisk setup is only effective if the LVM, logical volume manager system is used. In any other case where the filesystem itself offers volume management capabilities there are no extra filesystem labels which can be applied per volume

The volume size specification ‘all’ makes this volume to take the rest space available on the system. It’s only allowed to specify one all size volume

The root volume in a systemdisk setup is handled in a special way. It is not allowed to setup a custom name or mountpoint for the root volume. Therefore the size of the root volume can be setup via the @root volume name. This check looks up the volume setup and searches if there is a configuration for the ‘/’ mountpoint which would cause the image build to fail

If the image is classified to be used as Xen image, it can be either a Xen Server(dom0) or a Xen guest. The image configuration is checked if the information uniquely identifies the image as such

Return boolean value to express if the image build and bundle should contain a .changes file. The .changes file contains the package changelog information from all packages installed into the image.

By default the creation is switched on. When building in the Open Build Service the default is switched off because obs provides a .report file containing the same information.

if no configuration exists None is returned
