Overview ¶
Package extendedserverattributes provides the ability to extend a server result with the extended usage information.
Example to Get basic extended information:
type serverAttributesExt struct {
servers.Server
extendedserverattributes.ServerAttributesExt
}
var serverWithAttributesExt serverAttributesExt
err := servers.Get(computeClient, "d650a0ce-17c3-497d-961a-43c4af80998a").ExtractInto(&serverWithAttributesExt)
if err != nil {
panic(err)
}
fmt.Printf("%+v\n", serverWithAttributesExt)
Example to get additional fields with microversion 2.3 or later
computeClient.Microversion = "2.3"
result := servers.Get(computeClient, "d650a0ce-17c3-497d-961a-43c4af80998a")
reservationID, err := extendedserverattributes.ExtractReservationID(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%s\n", reservationID)
launchIndex, err := extendedserverattributes.ExtractLaunchIndex(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%d\n", launchIndex)
ramdiskID, err := extendedserverattributes.ExtractRamdiskID(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%s\n", ramdiskID)
kernelID, err := extendedserverattributes.ExtractKernelID(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%s\n", kernelID)
hostname, err := extendedserverattributes.ExtractHostname(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%s\n", hostname)
rootDeviceName, err := extendedserverattributes.ExtractRootDeviceName(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%s\n", rootDeviceName)
userData, err := extendedserverattributes.ExtractUserData(result.Result)
if err != nil {
panic(err)
}
fmt.Printf("%s\n", userData)

Functions ¶
func ExtractHostname ¶
func ExtractHostname(r gophercloud.Result) (string, error)
ExtractHostname will extract the hostname attribute. This requires the client to be set to microversion 2.3 or later.
func ExtractKernelID ¶
func ExtractKernelID(r gophercloud.Result) (string, error)
ExtractKernelID will extract the kernel_id attribute. This requires the client to be set to microversion 2.3 or later.
func ExtractLaunchIndex ¶
func ExtractLaunchIndex(r gophercloud.Result) (int, error)
ExtractLaunchIndex will extract the launch_index attribute. This requires the client to be set to microversion 2.3 or later.
func ExtractRamdiskID ¶
func ExtractRamdiskID(r gophercloud.Result) (string, error)
ExtractRamdiskID will extract the ramdisk_id attribute. This requires the client to be set to microversion 2.3 or later.
func ExtractReservationID ¶
func ExtractReservationID(r gophercloud.Result) (string, error)
ExtractReservationID will extract the reservation_id attribute. This requires the client to be set to microversion 2.3 or later.
func ExtractRootDeviceName ¶
func ExtractRootDeviceName(r gophercloud.Result) (string, error)
ExtractRootDeviceName will extract the root_device_name attribute. This requires the client to be set to microversion 2.3 or later.
func ExtractUserData ¶
func ExtractUserData(r gophercloud.Result) (string, error)
ExtractUserData will extract the userdata attribute. This requires the client to be set to microversion 2.3 or later.
Types ¶
type ServerAttributesExt ¶
type ServerAttributesExt struct {
Host string `json:"OS-EXT-SRV-ATTR:host"`
InstanceName string `json:"OS-EXT-SRV-ATTR:instance_name"`
HypervisorHostname string `json:"OS-EXT-SRV-ATTR:hypervisor_hostname"`
}
ServerAttributesExt represents basic OS-EXT-SRV-ATTR server response fields. You should use extract methods from microversions.go to retrieve additional fields.
