import ( "github.com/rackspace/gophercloud" "github.com/rackspace/gophercloud/auth/aksk" "github.com/rackspace/gophercloud/openstack/compute/v2/servers" ) func main() { // Create an authentication client using an Access Key and Secret Key authClient := aksk.NewAuthenticator(identityEndpoint, accessKey, secretKey) // Create a Compute ServiceClient using the authentication client computeClient, err := gophercloud.NewClient(identityEndpoint, authClient) if err != nil { panic(err) } // List all servers in the default project allPages, err := servers.List(computeClient, servers.ListOpts{}).AllPages() if err != nil { panic(err) } // Print each server name serverList, err := servers.ExtractServers(allPages) if err != nil { panic(err) } for _, server := range serverList { fmt.Println(server.Name) } }In this example, we use the ServiceClient to authenticate with Rackspace using access and secret keys, and then use the Compute API to list all servers in the default project. We then use the ExtractServers function to extract the server names from the response. Overall, the go github.com.rackspace.gophercloud package provides a comprehensive library for interacting with Rackspace services, making it easy to integrate Rackspace resources into Go applications.
