func NewDryRunClientWithOpts

func NewDryRunClientWithOpts(opts DryRunClientOptions) clientset.Interface

NewDryRunClientWithOpts returns a clientset.Interface that can be used normally for talking to the Kubernetes API. This client doesn't apply changes to the backend. The client gets GET/LIST values from the DryRunGetter implementation. This client logs all I/O to the writer w in YAML format

func PrintBytesWithLinePrefix

func PrintBytesWithLinePrefix(w io.Writer, objBytes []byte, linePrefix string)

PrintBytesWithLinePrefix prints objBytes to writer w with linePrefix in the beginning of every line

func TryRunCommand

func TryRunCommand(f func() error, failureThreshold int) error

TryRunCommand runs a function a maximum of failureThreshold times, and retries on error. If failureThreshold is hit; the last error is returned
