Service for the instanceGroups resource.

https://cloud.google.com/compute/docs/reference/rest/v1/instanceGroups

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

Functions

AddInstances(std::string const &, std::string const &, std::string const &, google::cloud::cpp::compute::v1::InstanceGroupsAddInstancesRequest const &, Options)

Adds a list of instances to the specified instance group.

All of the instances in the instance group must be in the same network/subnetwork. Read Adding instances for more information. https://cloud.google.com/compute/docs/reference/rest/v1/instanceGroups/addInstances

Parameters
Name	Description
project	std::string const & Project ID for this request.
zone	std::string const & The name of the zone where the instance group is located.
instance_group	std::string const & The name of the instance group where you are adding instances.

Returns
Type	Description
future< StatusOr< google::cloud::cpp::compute::v1::Operation > >	A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a [google.cloud.cpp.compute.v1.Operation] proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

AddInstances(google::cloud::cpp::compute::instance_groups::v1::AddInstancesRequest const &, Options)
