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)

}

ServerAttributesExt represents basic OS-EXT-SRV-ATTR server response fields. You should use extract methods from microversions.go to retrieve additional fields.
