Functions

func CleanDeleteVirtualMachine

func CleanDeleteVirtualMachine(az armhelpers.AKSEngineClient, logger *log.Entry, subscriptionID, resourceGroup, name string) error

CleanDeleteVirtualMachine deletes a VM and any associated OS disk

func RemoteRun

func RemoteRun(user string, addr string, port int, sshKey []byte, cmd string) (string, error)

RemoteRun executes remote command

func SafelyDrainNode

func SafelyDrainNode(az armhelpers.AKSEngineClient, logger *log.Entry, masterURL, kubeConfig, nodeName string, timeout time.Duration) error

SafelyDrainNode safely drains a node so that it can be deleted from the cluster

func SafelyDrainNodeWithClient

func SafelyDrainNodeWithClient(client armhelpers.KubernetesClient, logger *log.Entry, nodeName string, timeout time.Duration) error

SafelyDrainNodeWithClient safely drains a node so that it can be deleted from the cluster

func ScaleDownVMs

func ScaleDownVMs(az armhelpers.AKSEngineClient, logger *log.Entry, subscriptionID string, resourceGroup string, vmNames ...string) *list.List

ScaleDownVMs removes the vms in the provided list. Returns a list with details on each failure. all items in the list will always be of type *VMScalingErrorDetails

Types

type VMScalingErrorDetails

type VMScalingErrorDetails struct {
	Name  string
	Error error
}

VMScalingErrorDetails give the index in the agent pool that failed and the accompanying error
