openstack.compute.v2.flavor

The Flavor Class

The Flavor class inherits from Resource.

class openstack.compute.v2.flavor.Flavor(_synchronized=False, connection=None, **attrs)

The base resource

Parameters

  • _synchronized (bool) – This is not intended to be used directly. See new() and existing().

  • connection (openstack.connection.Connection) – Reference to the Connection being used. Defaults to None to allow Resource objects to be used without an active Connection, such as in unit tests. Use of self._connection in Resource code should protect itself with a check for None.

name

The name of this flavor.

original_name

The name of this flavor when returned by server list/show

description

The description of the flavor.

disk

Size of the disk this flavor offers. Type: int

is_public

True if this is a publicly visible flavor. False if this is a private image. Type: bool

ram

The amount of RAM (in MB) this flavor offers. Type: int

vcpus

The number of virtual CPUs this flavor offers. Type: int

swap

Size of the swap partitions.

ephemeral

Size of the ephemeral data disk attached to this server. Type: int

is_disabled

True if this flavor is disabled, False if not. Type: bool

rxtx_factor

The bandwidth scaling factor this flavor receives on the network.

extra_specs

A dictionary of the flavor’s extra-specs key-and-value pairs.

classmethod list(session, paginated=True, base_path='/flavors/detail', **params)

This method is a generator which yields resource objects.

This resource object list generator handles pagination and takes query params for response filtering.

Parameters

  • session (Adapter) – The session to use for making this request.

  • paginated (bool) – True if a GET to this resource returns a paginated series of responses, or False if a GET returns only one page of data. When paginated is False only one page of data will be returned regardless of the API’s support of pagination.

  • base_path (str) – Base part of the URI for listing resources, if different from base_path.

  • allow_unknown_params (bool) – True to accept, but discard unknown query parameters. This allows getting list of ‘filters’ and passing everything known to the server. False will result in validation exception when unknown query parameters are passed.

  • microversion (str) – API version to override the negotiated one.

  • params (dict) – These keyword arguments are passed through the _transpose() method to find if any of them match expected query parameters to be sent in the params argument to get(). They are additionally checked against the base_path format string to see if any path fragments need to be filled in by the contents of this argument. Parameters supported as filters by the server side are passed in the API call, remaining parameters are applied as filters to the retrieved results.

Returns

A generator of Resource objects.

Raises

MethodNotSupported if Resource.allow_list is not set to True.

Raises

InvalidResourceQuery if query contains invalid params.

Starting with 2.61 extra specs are returned with the flavor details, before that a separate call is required.

Parameters

session – The session to use for making this request.

Returns

The updated flavor.

create_extra_specs(session, specs)

Creates extra specs for a flavor.

Parameters

  • session – The session to use for making this request.

  • specs –

Returns

The updated flavor.

get_extra_specs_property(session, prop)

Get an individual extra spec property.

Parameters

  • session – The session to use for making this request.

  • prop – The property to fetch.

The value of the property if it exists, else None.

update_extra_specs_property(session, prop, val)

Update an extra spec for a flavor.

Parameters

  • session – The session to use for making this request.

  • prop – The property to update.

  • val – The value to update with.
