Functions

func CreatePubKeyHashAnnotation

func CreatePubKeyHashAnnotation(key ssh.PublicKey) string

CreatePubKeyHashAnnotation returns a formatted string which can be used for a public key annotation on a node. The annotation is the sha256 of the public key

func NewNodeConfig

func NewNodeConfig(c client.Client, clientset *kubernetes.Clientset, clusterServiceCIDR, wmcoNamespace string,
	instanceInfo *instance.Info, signer ssh.Signer, additionalLabels,
	additionalAnnotations map[string]string, platformType configv1.PlatformType) (*nodeConfig, error)

NewNodeConfig creates a new instance of nodeConfig to be used by the caller. hostName having a value will result in the VM's hostname being changed to the given value.

Types

type ErrWriter

type ErrWriter struct {
	// contains filtered or unexported fields
}

ErrWriter is a wrapper to enable error-level logging inside kubectl drainer implementation

func (ErrWriter) Write

func (ew ErrWriter) Write(p []byte) (n int, err error)

type OutWriter

type OutWriter struct {
	// contains filtered or unexported fields
}

OutWriter is a wrapper to enable info-level logging inside kubectl drainer implementation

func (OutWriter) Write

func (ow OutWriter) Write(p []byte) (n int, err error)
