Reference documentation and code samples for the Google Cloud Appengine Admin V1 Client class InstancesClient.
Service Description: Manages instances of a version.
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:
$instancesClient = new InstancesClient();
try {
$operationResponse = $instancesClient->debugInstance();
$operationResponse->pollUntilComplete();
if ($operationResponse->operationSucceeded()) {
$result = $operationResponse->getResult();
// doSomethingWith($result)
} else {
$error = $operationResponse->getError();
// handleError($error)
}
// Alternatively:
// start the operation, keep the operation name, and resume later
$operationResponse = $instancesClient->debugInstance();
$operationName = $operationResponse->getName();
// ... do other work
$newOperationResponse = $instancesClient->resumeOperation($operationName, 'debugInstance');
while (!$newOperationResponse->isDone()) {
// ... do other work
$newOperationResponse->reload();
}
if ($newOperationResponse->operationSucceeded()) {
$result = $newOperationResponse->getResult();
// doSomethingWith($result)
} else {
$error = $newOperationResponse->getError();
// handleError($error)
}
} finally {
$instancesClient->close();
}
This service has a new (beta) implementation. See Google\Cloud\AppEngine\V1\Client\InstancesClient to use the new surface.

__construct
Constructor.
Parameters | |
---|---|
Name | Description |
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 |
↳ 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 |
↳ 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 Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() 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. |
debugInstance
Enables debugging on a VM instance. This allows you to use the SSH command to connect to the virtual machine where the instance lives.
While in "debug mode", the instance continues to serve live traffic. You should delete the instance when you are done debugging and then allow the system to take over and determine if another instance should be started.
Only applicable for instances in App Engine flexible environment.
Parameters | |
---|---|
Name | Description |
optionalArgs |
array
Optional. |
↳ name |
string
Name of the resource requested. Example: |
↳ sshKey |
string
Public SSH key to add to the instance. Examples: * |
↳ 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. |

}
deleteInstance
Stops a running instance.
The instance might be automatically recreated based on the scaling settings of the version. For more information, see "How Instances are Managed" (standard environment | flexible environment).
To ensure that instances are not re-created and avoid getting billed, you
can stop all instances within the target version by changing the serving
status of the version to STOPPED
with the
apps.services.versions.patch
method.
