Methods

Create()

public static InstancesClient Create()

Synchronously creates a InstancesClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use InstancesClientBuilder.

Returns
Type	Description
InstancesClient	The created InstancesClient.

CreateAsync(CancellationToken)

public static Task<InstancesClient> CreateAsync(CancellationToken cancellationToken = default)

Asynchronously creates a InstancesClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use InstancesClientBuilder.

Parameter
Name	Description
cancellationToken	CancellationToken The CancellationToken to use while creating the client.

Returns
Type	Description
TaskInstancesClient	The task representing the created InstancesClient.

DebugInstance(DebugInstanceRequest, CallSettings)

public virtual Operation<Instance, OperationMetadataV1> DebugInstance(DebugInstanceRequest request, CallSettings callSettings = null)

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
request	DebugInstanceRequest The request object containing all of the parameters for the API call.
callSettings	CallSettings If not null, applies overrides to this RPC call.

Returns
Type	Description
OperationInstanceOperationMetadataV1	The RPC response.

Example

// Create client
InstancesClient instancesClient = InstancesClient.Create();
// Initialize request argument(s)
DebugInstanceRequest request = new DebugInstanceRequest { Name = "", SshKey = "", };
// Make the request
Operation<Instance, OperationMetadataV1> response = instancesClient.DebugInstance(request);

// Poll until the returned long-running operation is complete
Operation<Instance, OperationMetadataV1> completedResponse = response.PollUntilCompleted();
// Retrieve the operation result
Instance result = completedResponse.Result;

// Or get the name of the operation
string operationName = response.Name;
// This name can be stored, then the long-running operation retrieved later by name
Operation<Instance, OperationMetadataV1> retrievedResponse = instancesClient.PollOnceDebugInstance(operationName);
// Check if the retrieved long-running operation has completed
if (retrievedResponse.IsCompleted)
{
    // If it has completed, then access the result
    Instance retrievedResult = retrievedResponse.Result;
}

DebugInstanceAsync(DebugInstanceRequest, CallSettings)

DeleteInstance(DeleteInstanceRequest, CallSettings)

public virtual Operation<Empty, OperationMetadataV1> DeleteInstance(DeleteInstanceRequest request, CallSettings callSettings = null)

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.
