func FindPodByPrefix 

func FindPodByPrefix(clientSet *kubernetes.Clientset, namespace, prefix, labelSelector string) (*k8sv1.Pod, error)

FindPodByPrefix finds the first pod which has the passed in prefix. Returns error if multiple pods with the same prefix are found.

func FormatTestData 

func FormatTestData(srcFile, tgtDir string, targetFormats ...string) (string, error)

FormatTestData accepts the path of a single file (srcFile) and attempts to generate an output file in the format defined by targetFormats (e.g. ".tar", ".gz" will produce a .tar.gz formatted file). The output file is written to the directory in `tgtDir`. returns: 

(string) Path of output file
(error)  Errors that occur during formatting

func GetServiceInNamespace 

func GetServiceInNamespace(c *kubernetes.Clientset, ns, name string) (*v1.Service, error)

GetServiceInNamespace retries get on service `name` in namespace `ns` until timeout or IsNotFound error. Ignores api errors that may be intermittent. Returns pointer to service (nil on error) or an error (nil on success)

func GetServiceInNamespaceOrDie 

func GetServiceInNamespaceOrDie(c *kubernetes.Clientset, ns, name string) *v1.Service

GetServiceInNamespaceOrDie attempts to get the service in namespace `ns` by `name`. Returns pointer to service on success. Panics on error.

func GetServiceNodePortByName 

func GetServiceNodePortByName(svc *v1.Service, name string) (int, error)

GetServiceNodePortByName scans a service's nodePorts for a name matching the `name` parameter and returns the associated port integer or an error if not match is found.

func GetServicePortByName 

func GetServicePortByName(svc *v1.Service, name string) (int, error)

GetServicePortByName scans a service's ports for names matching `name`. Returns integer port value (0 on error) and error (nil on success).

func GetServicesInNamespaceByLabel 

func GetServicesInNamespaceByLabel(c *kubernetes.Clientset, ns, labelSelector string) (*v1.ServiceList, error)

GetServicesInNamespaceByLabel retries get of services in namespace `ns` by `labelSelector` until timeout. Ignores api errors that may be intermittent. Returns pointer to ServiceList (nil on error) and an error (nil on success)
