Image API v2

For details on how to use image, see Using OpenStack Image

The Image v2 Class

The image high-level interface is available through the image member of a Connection object. The image member will only be added if the service is detected.

Image Operations

class openstack.image.v2._proxy.Proxy(session, statsd_client=None, statsd_prefix=None, prometheus_counter=None, prometheus_histogram=None, influxdb_config=None, influxdb_client=None, *args, **kwargs)
import_image(image, method='glance-direct', uri=None, store=None, stores=None, all_stores=None, all_stores_must_succeed=None)

Import data to an existing image

Interoperable image import process are introduced in the Image API v2.6. It mainly allow image importing from an external url and let Image Service download it by itself without sending binary data at image creation.

Parameters

  • image – The value can be the ID of a image or a Image instance.

  • method – Method to use for importing the image. A valid value is glance-direct or web-download.

  • uri – Required only if using the web-download import method. This url is where the data is made available to the Image service.

  • store – Used when enabled_backends is activated in glance. The value can be the id of a store or a Store instance.

  • stores – List of stores to be used when enabled_backends is activated in glance. List values can be the id of a store or a Store instance.

  • all_stores – Upload to all available stores. Mutually exclusive with store and stores.

  • all_stores_must_succeed – When set to True, if an error occurs during the upload in at least one store, the worfklow fails, the data is deleted from stores where copying is done (not staging), and the state of the image is unchanged. When set to False, the workflow will fail (data deleted from stores, …) only if the import fails on all stores specified by the user. In case of a partial success, the locations added to the image will be the stores where the data has been correctly uploaded. Default is True.

Returns

None

stage_image(image, filename=None, data=None)

Stage binary image data

Parameters

  • image – The value can be the ID of a image or a Image instance.

  • filename – Optional name of the file to read data from.

  • data – Optional data to be uploaded as an image.

Returns

The results of image creation

Return type

Image

upload_image(container_format=None, disk_format=None, data=None, **attrs)

Create and upload a new image from attributes

Parameters

  • container_format – Format of the container. A valid value is ami, ari, aki, bare, ovf, ova, or docker.

  • disk_format – The format of the disk. A valid value is ami, ari, aki, vhd, vmdk, raw, qcow2, vdi, or iso.

  • data – The data to be uploaded as an image.

  • attrs (dict) – Keyword arguments which will be used to create a Image, comprised of the properties on the Image class.

Returns

The results of image creation

Return type

Image

download_image(image, stream=False, output=None, chunk_size=1024)

Download an image

This will download an image to memory when stream=False, or allow streaming downloads using an iterator when stream=True. For examples of working with streamed responses, see Downloading an Image with stream=True.

Parameters

  • image – The value can be either the ID of an image or a Image instance.

  • stream (bool) –

    When True, return a requests.Response instance allowing you to iterate over the response data stream instead of storing its entire contents in memory. See requests.Response.iter_content() for more details. NOTE: If you do not consume the entirety of the response you must explicitly call requests.Response.close() or otherwise risk inefficiencies with the requests library’s handling of connections.

    When False, return the entire contents of the response.

  • output – Either a file object or a path to store data into.

  • chunk_size (int) – size in bytes to read from the wire and buffer at one time. Defaults to 1024

Returns

When output is not given - the bytes comprising the given Image when stream is False, otherwise a requests.Response instance. When output is given - a Image instance.

delete_image(image, ignore_missing=True)

Delete an image

Parameters

  • image – The value can be either the ID of an image or a Image instance.

  • ignore_missing (bool) – When set to False ResourceNotFound will be raised when the image does not exist. When set to True, no exception will be set when attempting to delete a nonexistent image.

Returns

None

find_image(name_or_id, ignore_missing=True)

Find a single image

Parameters

  • name_or_id – The name or ID of a image.

create_image(name, filename=None, container=None, md5=None, sha256=None, disk_format=None, container_format=None, disable_vendor_agent=True, allow_duplicates=False, meta=None, wait=False, timeout=3600, data=None, validate_checksum=False, use_import=False, stores=None, all_stores=None, all_stores_must_succeed=None, **kwargs)

Upload an image.

Parameters

  • name (str) – Name of the image to create. If it is a pathname of an image, the name will be constructed from the extensionless basename of the path.

  • filename (str) – The path to the file to upload, if needed. (optional, defaults to None)

  • data – Image data (string or file-like object). It is mutually exclusive with filename

  • container (str) – Name of the container in swift where images should be uploaded for import if the cloud requires such a thing. (optional, defaults to ‘images’)

  • md5 (str) – md5 sum of the image file. If not given, an md5 will be calculated.

  • sha256 (str) – sha256 sum of the image file. If not given, an md5 will be calculated.

  • disk_format (str) – The disk format the image is in. (optional, defaults to the os-client-config config value for this cloud)

  • container_format (str) – The container format the image is in. (optional, defaults to the os-client-config config value for this cloud)

  • disable_vendor_agent (bool) – Whether or not to append metadata flags to the image to inform the cloud in question to not expect a vendor agent to be runing. (optional, defaults to True)

  • allow_duplicates – If true, skips checks that enforce unique image name. (optional, defaults to False)

  • meta – A dict of key/value pairs to use for metadata that bypasses automatic type conversion.

  • wait (bool) – If true, waits for image to be created. Defaults to true - however, be aware that one of the upload methods is always synchronous.

  • timeout – Seconds to wait for image creation. None is forever.

  • validate_checksum (bool) – If true and cloud returns checksum, compares return value with the one calculated or passed into this call. If value does not match - raises exception. Default is ‘false’

  • use_import (bool) – Use the interoperable image import mechanism to import the image. This defaults to false because it is harder on the target cloud so should only be used when needed, such as when the user needs the cloud to transform image format. If the cloud has disabled direct uploads, this will default to true.

  • stores – List of stores to be used when enabled_backends is activated in glance. List values can be the id of a store or a Store instance. Implies use_import equals True.

  • all_stores – Upload to all available stores. Mutually exclusive with store and stores. Implies use_import equals True.

  • all_stores_must_succeed – When set to True, if an error occurs during the upload in at least one store, the worfklow fails, the data is deleted from stores where copying is done (not staging), and the state of the image is unchanged. When set to False, the workflow will fail (data deleted from stores, …) only if the import fails on all stores specified by the user. In case of a partial success, the locations added to the image will be the stores where the data has been correctly uploaded. Default is True. Implies use_import equals True.

Additional kwargs will be passed to the image creation as additional metadata for the image and will have all values converted to string except for min_disk, min_ram, size and virtual_size which will be converted to int.

If you are sure you have all of your data types correct or have an advanced need to be explicit, use meta. If you are just a normal consumer, using kwargs is likely the right choice.

If a value is in meta and kwargs, meta wins.

Returns

A munch.Munch of the Image object

Raises

SDKException if there are problems uploading
