import ( "github.com/gophercloud/gophercloud" "github.com/gophercloud/gophercloud/openstack/compute/v2/servers" ) // ... func deleteInstance(client *gophercloud.ServiceClient, instanceID string) error { res := servers.Delete(client, instanceID) if res.Err != nil { return res.Err } return nil }In this example, the deleteInstance function takes a ServiceClient and an instance ID as arguments. It uses the `servers.Delete` method to delete the instance, and returns an error if the operation fails. Overall, the gophercloud package library provides a robust set of tools for working with OpenStack cloud resources.
