## Instance Methods

Adds an access config to an instance's network interface.

A description of how to use this function

Retrieves the next page of results.

Attaches a Disk resource to an instance.

Deletes the specified Instance resource. For more information, see Shutting down an instance.

Deletes an access config from an instance's network interface.

Detaches a disk from an instance.

Returns the specified instance resource.

Returns the specified instance's serial port output.

Creates an instance resource in the specified project using the data included in the request.

Retrieves the list of instance resources contained within the specified zone.

Retrieves the next page of results.

Performs a hard reset on the instance.

Sets the auto-delete flag for a disk attached to an instance.

Sets metadata for the specified instance to the data included in the request.

Sets an instance's scheduling options.

Sets tags for the specified instance to the data included in the request.

This method starts an instance that was stopped using the using the instances().stop method. For more information, see Restart an instance.

This method stops a running instance, shutting it down cleanly, and allows you to restart the instance at a later time. Stopped instances do not incur per-minute, virtual machine usage charges while they are stopped, but any resources that the virtual machine is using, such as persistent disks and static IP addresses,will continue to be charged until they are deleted. For more information, see Stopping an instance.
