IntMin takes a list of integers as strings and returns the minimum.

func IntPtr

func IntPtr(i int) *int

IntPtr returns a pointer to the passed integer.

func ListMerge

func ListMerge(listStrs []string) (string, error)

ListMerge takes a list comma separated strings and performs a set union on them.

func MakeLabeler

func MakeLabeler(nn types.NamespacedName, labels map[string]string, obj obj.LabeledClowdObject) func(metav1.Object)

MakeLabeler creates a function that will label objects with metadata from the given namespaced name and labels

func MakePVC

func MakePVC(pvc *core.PersistentVolumeClaim, nn types.NamespacedName, labels map[string]string, size string, baseResource obj.ClowdObject)

MakePVC takes a PVC object and applies the correct ownership and labels to it.

func MakeService

MakeService takes a service object and applies the correct ownership and labels to it.

func RandString

func RandString(n int) string

RandString generates a random string of length n

func RandStringLower

func RandStringLower(n int) string

RandStringLower generates a random string of length n

func UpdateAllOrErr

UpdateAllOrErr queries the client for a range of objects and returns updater objects for each.

Types

type Updater

type Updater bool

Updater is a bool type object with functions attached that control when a resource should be created or applied.

func UpdateOrErr

func UpdateOrErr(err error) (Updater, error)

UpdateOrErr returns an update object if the err supplied is nil.

func (*Updater) Apply

func (u *Updater) Apply(ctx context.Context, cl client.Client, obj client.Object) error

Apply will apply the resource if it already exists, and create it if it does not. This is based on the bool value of the Update object.
