Reference documentation and code samples for the Google Cloud Dataproc V1 Client class AutoscalingPolicyServiceClient.
Service Description: The API interface for managing autoscaling policies in the Dataproc API.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:
$autoscalingPolicyServiceClient = new AutoscalingPolicyServiceClient();
try {
$formattedParent = $autoscalingPolicyServiceClient->regionName('[PROJECT]', '[REGION]');
$policy = new AutoscalingPolicy();
$response = $autoscalingPolicyServiceClient->createAutoscalingPolicy($formattedParent, $policy);
} finally {
$autoscalingPolicyServiceClient->close();
}
Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.
Methods
autoscalingPolicyName
Formats a string containing the fully-qualified path to represent a autoscaling_policy resource.
project
string
location
string
autoscalingPolicy
string
string
locationName
Formats a string containing the fully-qualified path to represent a location resource.
project
string
location
string
string
projectLocationAutoscalingPolicyName
Formats a string containing the fully-qualified path to represent a project_location_autoscaling_policy resource.
project
string
location
string
autoscalingPolicy
string
string
projectRegionAutoscalingPolicyName
Formats a string containing the fully-qualified path to represent a project_region_autoscaling_policy resource.
project
string
region
string
autoscalingPolicy
string
string
regionName
Formats a string containing the fully-qualified path to represent a region resource.
project
string
region
string
string
parseName
Parses a formatted name string and returns an associative array of the components in the name.
The following name formats are supported: Template: Pattern
- autoscalingPolicy: projects/{project}/locations/{location}/autoscalingPolicies/{autoscaling_policy}
- location: projects/{project}/locations/{location}
- projectLocationAutoscalingPolicy: projects/{project}/locations/{location}/autoscalingPolicies/{autoscaling_policy}
- projectRegionAutoscalingPolicy: projects/{project}/regions/{region}/autoscalingPolicies/{autoscaling_policy}
- region: projects/{project}/regions/{region}
The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.
formattedName
string
The formatted name string
template
string
Optional name of template to match
array
__construct
Constructor.
options
array
Optional. Options for configuring the service API wrapper.
↳ apiEndpoint
string
The address of the API remote host. May optionally include the port, formatted as "
↳ credentials
string|array|FetchAuthTokenInterface|CredentialsWrapper
The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage : In addition, this option can also accept a pre-constructed {@see} object or {@see} object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
↳ credentialsConfig
array
Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see {@see} .
↳ disableRetries
bool
Determines whether or not retries defined by the client configuration should be disabled. Defaults to false
.
↳ clientConfig
string|array
Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
↳ transport
string|TransportInterface
The transport used for executing network requests. May be either the string rest
or grpc
. Defaults to grpc
if gRPC support is detected on the system. Advanced usage
: Additionally, it is possible to pass in an already instantiated {@see} object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
↳ transportConfig
array
Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the {@see} and {@see} methods for the supported options.
↳ clientCertSource
callable
A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.
createAutoscalingPolicy
Creates new autoscaling policy.
parent
string
Required. The "resource name" of the region or location, as described in https://cloud.google.com/apis/design/resource_names
. * For projects.regions.autoscalingPolicies.create
, the resource name of the region has the following format: projects/{project_id}/regions/{region}
* For projects.locations.autoscalingPolicies.create
, the resource name of the location has the following format: projects/{project_id}/locations/{location}
policy
optionalArgs
array
Optional.
↳ retrySettings
RetrySettings|array
Retry settings to use for this call. Can be a {@see} object, or an associative array of retry settings parameters. See the documentation on {@see} for example usage.
