Functions

func EnsureNamespaceExistsAndIsReady

func EnsureNamespaceExistsAndIsReady(namespace *corev1api.Namespace, client corev1client.NamespaceInterface, timeout time.Duration) (bool, error)

EnsureNamespaceExistsAndIsReady attempts to create the provided Kubernetes namespace. It returns two values: a bool indicating whether or not the namespace is ready, and an error if the create failed for a reason other than that the namespace already exists. Note that in the case where the namespace already exists and is not ready, this function will return (false, nil). If the namespace exists and is marked for deletion, this function will wait up to the timeout for it to fully delete.

func GetVolumeDirectory

func GetVolumeDirectory(pod *corev1api.Pod, volumeName string, pvcLister corev1listers.PersistentVolumeClaimLister, pvLister corev1listers.PersistentVolumeLister) (string, error)

GetVolumeDirectory gets the name of the directory on the host, under /var/lib/kubelet/pods/<podUID>/volumes/, where the specified volume lives. For volumes with a CSIVolumeSource, append "/mount" to the directory name.

func NamespaceAndName

func NamespaceAndName(objMeta metav1.Object) string

NamespaceAndName returns a string in the format <namespace>/<name>

func ParseResourceRequirements

func ParseResourceRequirements(cpuRequest, memRequest, cpuLimit, memLimit string) (corev1.ResourceRequirements, error)

ParseResourceRequirements takes a set of CPU and memory requests and limit string values and returns a ResourceRequirements struct to be used in a Container. An error is returned if we cannot parse the request/limit.
