Lists autoscaling policies in the project.
Example:
>>> from google.cloud import dataproc_v1beta2
>>>
>>> client = dataproc_v1beta2.AutoscalingPolicyServiceClient()
>>>
>>> parent = client.region_path('[PROJECT]', '[REGION]')
>>>
>>> # Iterate over all results
>>> for element in client.list_autoscaling_policies(parent):
... # process element
... pass
>>>
>>>
>>> # Alternatively:
>>>
>>> # Iterate over results one page at a time
>>> for page in client.list_autoscaling_policies(parent).pages:
... for element in page:
... # process element
... pass
Args:
parent (str): Required. The "resource name" of the region or location, as described in
https://cloud.google.com/apis/design/resource\_names.
- For ``projects.regions.autoscalingPolicies.list``, the resource name
of the region has the following format:
``projects/{project_id}/regions/{region}``
- For ``projects.locations.autoscalingPolicies.list``, the resource
name of the location has the following format:
``projects/{project_id}/locations/{location}``
page_size (int): The maximum number of resources contained in the
underlying API response. If page streaming is performed per-
resource, this parameter does not affect the return value. If page
streaming is performed per-page, this determines the maximum number
of resources in a page.
retry (Optional[google.api_core.retry.Retry]): A retry object used
to retry requests. If ``None`` is specified, requests will
be retried using a default configuration.
timeout (Optional[float]): The amount of time, in seconds, to wait
for the request to complete. Note that if ``retry`` is
specified, the timeout applies to each individual attempt.
metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
that is provided to the method.
Returns:
A :class:`~google.api_core.page_iterator.PageIterator` instance.
An iterable of :class:`~google.cloud.dataproc_v1beta2.types.AutoscalingPolicy` instances.
You can also iterate over the pages of the response
using its `pages` property.
Raises:
google.api_core.exceptions.GoogleAPICallError: If the request
failed for any reason.
google.api_core.exceptions.RetryError: If the request failed due
to a retryable error and retry attempts failed.
ValueError: If the parameters are invalid.
