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)

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

Create an image and optionally upload data

Create a new image. If filename or data are provided, it will also upload data to this image.

Note that uploading image data is actually quite a complicated procedure. There are three ways to upload an image:

Image upload
Image import
Image tasks

If the image tasks API is enabled, this must be used. However, this API is deprecated since the Image service’s Mitaka (12.0.0) release and is now admin-only. Assuming this API is not enabled, you may choose between image upload or image import. Image import is more powerful and allows you to upload data from multiple sources including other glance instances. It should be preferred on all services that support it.

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)
tags (list) – List of tags for this image. Each tag is a string of at most 255 chars.
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 ‘glance-direct’ method of 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. If you wish to use other import methods, use the import_image method instead.
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: The results of image creation
Return type: Image
Raises: SDKException if there are problems uploading

import_image(image, method='glance-direct', *, uri=None, remote_region=None, remote_image_id=None, remote_service_interface=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. Not all deployments support all methods. One of: glance-direct (default), web-download, glance-download, or copy-image. Use of glance-direct requires the image be first staged.
uri – Required only if using the web-download import method. This url is where the data is made available to the Image service.
remote_region – The remote glance region to download the image from when using glance-download.
remote_image_id – The ID of the image to import from the remote glance when using glance-download.
remote_service_interface – The remote glance service interface to use when using glance-download.
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

The raw response from the request.

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

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

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
