class kiwi.storage.subformat.base.DiskFormatBase(xml_state: XMLState, root_dir: str, target_dir: str, custom_args: Optional[dict] = None)

Bases: object

Base class to create disk formats from a raw disk image

Parameters

• arch (string) – Defaults.get_platform_name

• target_dir (string) – target directory path name

• custom_args (dict) – custom format options dictionary

create_image_format() → None

Create disk format

Implementation in specialized disk format class required

static get_qemu_option_list(custom_args: dict) → list

Create list of qemu options from custom_args dict

Parameters

custom_args (dict) – arguments

Returns

qemu option list

Return type

list

Create target file path name for specified format

Parameters

format_name (string) – disk format name

Returns

file path name

Return type

str

has_raw_disk() → bool

Check if the base raw disk image exists

Returns

True or False

Return type

post_init(custom_args: dict) → None

Post initialization method

Implementation in specialized disk format class if required

Parameters

custom_args (dict) – unused

resize_raw_disk(size_bytes, append=False)

Resize raw disk image to specified size. If the request would actually shrink the disk an exception is raised. If the disk got changed the method returns True, if the new size is the same as the current size nothing gets resized and the method returns False

Parameters

size (int) – size in bytes

Returns

True or False

Return type

bool

store_to_result(result: Result)

Store result file of the format conversion into the provided result instance.

By default only the converted image file will be stored as compressed file. Subformats which creates additional metadata files or want to use other result flags needs to overwrite this method

Parameters

result (object) – Instance of Result

kiwi.storage.subformat.gce Module

class kiwi.storage.subformat.gce.DiskFormatGce(xml_state: XMLState, root_dir: str, target_dir: str, custom_args: Optional[dict] = None)

Bases: DiskFormatBase

Create GCE - Google Compute Engine image format

create_image_format() → None

Create GCE disk format and manifest

get_target_file_path_for_format(format_name)

Google requires the image name to follow their naming convetion. Therefore it’s required to provide a suitable name by overriding the base class method

Parameters

format_name (string) – gce

Returns

file path name

Return type

str

post_init(custom_args: dict) → None

GCE disk format post initialization method

Store disk tag from custom args

Parameters

custom_args (dict) –

custom gce argument dictionary

{'--tag': 'billing_code'}

store_to_result(result: Result) → None

Store result file of the gce format conversion into the provided result instance. In this case compression is unwanted because the gce tarball is already created as a compressed archive

Parameters

result (object) – Instance of Result

qcow2 disk format post initialization method

Store qemu options as list from custom args dict

Parameters

custom_args (dict) – custom qemu arguments dictionary

store_to_result(result: Result) → None

Store result file of the format conversion into the provided result instance.

In case of a qcow2 format we store the result uncompressed Since the format conversion only takes the real bytes into account such that the sparseness of the raw disk will not result in the output format and can be taken one by one

Parameters

result (object) – Instance of Result

kiwi.storage.subformat.vagrant_base Module

class kiwi.storage.subformat.vagrant_base.DiskFormatVagrantBase(xml_state: XMLState, root_dir: str, target_dir: str, custom_args: Optional[dict] = None)

Bases: DiskFormatBase

Base class for creating vagrant boxes.

The documentation of the vagrant box format can be found here: https://www.vagrantup.com/docs/boxes/format.html In a nutshell, a vagrant box is a tar, tar.gz or zip archive of the following:

1. metadata.json: A json file that contains the name of the provider and arbitrary additional data (that vagrant doesn’t care about).

2. Vagrantfile: A Vagrantfile which defines the boxes’ MAC address. It can be also used to define other settings of the box, e.g. the method via which the /vagrant/ directory is shared. This file is either automatically generated by KIWI or we use a file that has been provided by the user (depends on the setting in vagrantconfig.embebbed_vagrantfile)

3. The actual virtual disk image: this is provider specific and vagrant simply forwards it to your virtual machine provider.

Required methods/variables that child classes must implement:

• vagrant_post_init()

  post initializing method that has to specify the vagrant provider name in provider and the box name in image_format. Note: new providers also needs to be specified in the schema and the box name needs to be registered to kiwi.defaults.Defaults.get_disk_format_types()

• create_box_img()

Optional methods:

• get_additional_metadata()

• get_additional_vagrant_config_settings()

create_box_img(temp_image_dir: str) → List[str]

Provider specific image creation step: this function creates the actual box image. It must be implemented by a child class.

create_image_format() → None

Create a vagrant box for any provider. This includes:

• creation of box metadata.json

• creation of box Vagrantfile (either from scratch or by using the user provided Vagrantfile)

• creation of result format tarball from the files created above

get_additional_metadata() → Dict

Provide create_image_format() with additional metadata that will be included in metadata.json.

The default implementation returns an empty dictionary.

Returns

A dictionary that is serializable to JSON

Return type

dict

get_additional_vagrant_config_settings() → str

Supply additional configuration settings for vagrant to be included in the resulting box.

This function can be used by child classes to customize the behavior for different providers: the supplied configuration settings get forwarded to VagrantConfigTemplate.get_template() as the parameter custom_settings and included in the Vagrantfile.

The default implementation returns nothing.

Returns

additional vagrant settings

Return type

str

post_init(custom_args: Dict[str, vagrantconfig])

vagrant disk format post initialization method

Parameters

custom_args (dict) –

store_to_result(result: Result) → None

Store result file of the vagrant format conversion into the provided result instance. In this case compression is unwanted because the box is already created as a compressed tarball

Parameters

result (object) – Instance of Result

vagrant_post_init() → None
