Compute V1 Client - Class RegionInstanceGroupManagersClient (1.11.1)

Reference documentation and code samples for the Compute V1 Client class RegionInstanceGroupManagersClient.

Service Description: The RegionInstanceGroupManagers 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:

$regionInstanceGroupManagersClient = new RegionInstanceGroupManagersClient();
try {
    $instanceGroupManager = 'instance_group_manager';
    $project = 'project';
    $region = 'region';
    $regionInstanceGroupManagersAbandonInstancesRequestResource = new RegionInstanceGroupManagersAbandonInstancesRequest();
    $operationResponse = $regionInstanceGroupManagersClient->abandonInstances($instanceGroupManager, $project, $region, $regionInstanceGroupManagersAbandonInstancesRequestResource);
    $operationResponse->pollUntilComplete();
    if ($operationResponse->operationSucceeded()) {
        // if creating/modifying, retrieve the target resource
    } else {
        $error = $operationResponse->getError();
        // handleError($error)
    }
    // Alternatively:
    // start the operation, keep the operation name, and resume later
    $operationResponse = $regionInstanceGroupManagersClient->abandonInstances($instanceGroupManager, $project, $region, $regionInstanceGroupManagersAbandonInstancesRequestResource);
    $operationName = $operationResponse->getName();
    // ... do other work
    $newOperationResponse = $regionInstanceGroupManagersClient->resumeOperation($operationName, 'abandonInstances');
    while (!$newOperationResponse->isDone()) {
        // ... do other work
        $newOperationResponse->reload();
    }
    if ($newOperationResponse->operationSucceeded()) {
        // if creating/modifying, retrieve the target resource
    } else {
        $error = $newOperationResponse->getError();
        // handleError($error)
    }
} finally {
    $regionInstanceGroupManagersClient->close();
}

This service has a new (beta) implementation. See Google\Cloud\Compute\V1\Client\RegionInstanceGroupManagersClient to use the new surface.

Namespace

Google \ Cloud \ Compute \ V1

Methods

__construct

Constructor.

Parameters
NameDescription
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 Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper 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 Google\ApiCore\CredentialsWrapper::build() .

↳ 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. At the moment, supports only rest. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface 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 = [ 'rest' => [...], ]; See the Google\ApiCore\Transport\RestTransport::build() method 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.

abandonInstances

Flags the specified instances to be immediately removed from the managed instance group. Abandoning an instance does not delete the instance, but it does remove the instance from any target pools that are applied by the managed instance group. This method reduces the targetSize of the managed instance group by the number of instances that you abandon. This operation is marked as DONE when the action is scheduled even if the instances have not yet been removed from the group. You must separately verify the status of the abandoning action with the listmanagedinstances method. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

Parameters
NameDescription
instanceGroupManager string

Name of the managed instance group.

project string

Project ID for this request.

region string

Name of the region scoping this request.

regionInstanceGroupManagersAbandonInstancesRequestResource Google\Cloud\Compute\V1\RegionInstanceGroupManagersAbandonInstancesRequest

The body resource for this request

optionalArgs array

Optional.

↳ requestId string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

↳ retrySettings RetrySettings|array

Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

insert

Creates a managed instance group using the information that you specify in the request. After the group is created, instances in the group are created using the specified instance template. This operation is marked as DONE when the group is created even if the instances in the group have not yet been created. You must separately verify the status of the individual instances with the listmanagedinstances method. A regional managed instance group can contain up to 2000 instances.

Parameters
NameDescription
instanceGroupManagerResource Google\Cloud\Compute\V1\InstanceGroupManager

The body resource for this request

project string

Project ID for this request.

region string

Name of the region scoping this request.

optionalArgs array

Optional.

↳ requestId string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

↳ retrySettings RetrySettings|array

Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

list

Retrieves the list of managed instance groups that are contained within the specified region.

Parameters
NameDescription
project string

Project ID for this request.

region string

Name of the region scoping this request.

optionalArgs array

Optional.

↳ filter string

A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either =, !=, >, <, <=, >= or :. For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance. The : operator can be used with string fields to match substrings. For non-string fields it is equivalent to the = operator. The :* comparison can be used to test whether a key has been defined. For example, to find all objects with owner label use: labels.owner:* You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example: (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) If you want to use a regular expression, use the eq (equal) or ne (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: fieldname eq unquoted literal fieldname eq 'single quoted literal' fieldname eq "double quoted literal" (fieldname1 eq literal) (fieldname2 ne "literal") The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use name ne .*instance.

↳ maxResults int

The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)

↳ orderBy string

Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by name or creationTimestamp desc is supported.

↳ pageToken string

A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.

↳ returnPartialSuccess bool

Opt-in for partial success behavior which provides partial results in case of failure. The default value is false.

↳ retrySettings RetrySettings|array

Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

patch

Updates a managed instance group using the information that you specify in the request. This operation is marked as DONE when the group is patched even if the instances in the group are still in the process of being patched. You must separately verify the status of the individual instances with the listmanagedinstances method. This method supports PATCH semantics and uses the JSON merge patch format and processing rules. If you update your group to specify a new template or instance configuration, it's possible that your intended specification for each VM in the group is different from the current state of that VM. To learn how to apply an updated configuration to the VMs in a MIG, see Updating instances in a MIG.

Parameters
NameDescription
instanceGroupManager string

The name of the instance group manager.

instanceGroupManagerResource Google\Cloud\Compute\V1\InstanceGroupManager

patchPerInstanceConfigs

Inserts or patches per-instance configurations for the managed instance group. perInstanceConfig.name serves as a key used to distinguish whether to perform insert or patch.

Parameters
NameDescription
instanceGroupManager string

The name of the managed instance group. It should conform to RFC1035.

project string

Project ID for this request.

region string

Name of the region scoping this request, should conform to RFC1035.

regionInstanceGroupManagerPatchInstanceConfigReqResource Google\Cloud\Compute\V1\RegionInstanceGroupManagerPatchInstanceConfigReq

The body resource for this request

optionalArgs array

Optional.

↳ requestId string

An optional request ID to identify requests. Specify a unique request ID so that if you must retry your request, the server will know to ignore the request if it has already been completed. For example, consider a situation where you make an initial request and the request times out. If you make the request again with the same request ID, the server can check if original operation with the same request ID was received, and if so, will ignore the second request. This prevents clients from accidentally creating duplicate commitments. The request ID must be a valid UUID with the exception that zero UUID is not supported ( 00000000-0000-0000-0000-000000000000).

↳ retrySettings RetrySettings|array

Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

recreateInstances

Flags the specified VM instances in the managed instance group to be immediately recreated. Each instance is recreated using the group's current configuration. This operation is marked as DONE when the flag is set even if the instances have not yet been recreated. You must separately verify the status of each instance by checking its currentAction field; for more information, see Checking the status of managed instances. If the group is part of a backend service that has enabled connection draining, it can take up to 60 seconds after the connection draining duration has elapsed before the VM instance is removed or deleted. You can specify a maximum of 1000 instances with this method per request.

Parameters
NameDescription
instanceGroupManager string

Name of the managed instance group.

project string

Project ID for this request.

resize

Changes the intended size of the managed instance group. If you increase the size, the group creates new instances using the current instance template. If you decrease the size, the group deletes one or more instances. The resize operation is marked DONE if the resize request is successful. The underlying actions take additional time. You must separately verify the status of the creating or deleting actions with the listmanagedinstances method.
