Methods

containsLabels(String key)

public boolean containsLabels(String key)

Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer's organizational needs and deployment strategies. Cloud Labels can be used to filter collections of resources. They can be used to control how resource metrics are aggregated. And they can be used as arguments to policy management rules (e.g. route, firewall, load balancing, etc.).

Label keys must be between 1 and 63 characters long and must conform to the following regular expression: a-z{0,62}.
Label values must be between 0 and 63 characters long and must conform to the regular expression [a-z0-9_-]{0,63}.
No more than 64 labels can be associated with a given resource.

See https://goo.gl/xmQnxf for more information on and examples of labels.

If you plan to use labels in your own code, please note that additional characters may be allowed in the future. And so you are advised to use an internal label representation, such as JSON, which doesn't rely upon specific characters being disallowed. For example, representing labels as the string: name + "" + value would prove problematic if we were to allow "" in a future release.

map<string, string> labels = 7;

Parameter

getNodeCount()

public int getNodeCount()

The number of nodes allocated to this instance. At most, one of either node_count or processing_units should be present in the message.

If autoscaling is enabled, node_count is treated as an OUTPUT_ONLY field and reflects the current number of nodes allocated to the instance.

This might be zero in API responses for instances that are not yet in the READY state.

If the instance has varying node count across replicas (achieved by setting asymmetric_autoscaling_options in autoscaling config), the node_count here is the maximum node count across all replicas.

For more information, see Compute capacity, nodes, and processing units.

`int`	The nodeCount.

getParserForType()

public Parser<Instance> getParserForType()

The number of processing units allocated to this instance. At most, one of either processing_units or node_count should be present in the message.

Users can set the processing_units field to specify the target number of processing units allocated to the instance.

If autoscaling is enabled, processing_units is treated as an OUTPUT_ONLY field and reflects the current number of processing units allocated to the instance.

This might be zero in API responses for instances that are not yet in the READY state.

If the instance has varying processing units per replica (achieved by setting asymmetric_autoscaling_options in autoscaling config), the processing_units here is the maximum processing units across all replicas.

For more information, see Compute capacity, nodes and processing units.

int32 processing_units = 9;

Returns
Type	Description
`int`	The processingUnits.

getReplicaComputeCapacity(int index)

public ReplicaComputeCapacity getReplicaComputeCapacity(int index)

Output only. Lists the compute capacity per ReplicaSelection. A replica selection identifies a set of replicas with common properties. Replicas identified by a ReplicaSelection are scaled with the same compute capacity.
