Functions

func CreateOrPatchControllerInstallation 

func CreateOrPatchControllerInstallation(g gardencore.Interface, meta metav1.ObjectMeta, transform func(*gardencorev1alpha1.ControllerInstallation) *gardencorev1alpha1.ControllerInstallation) (*gardencorev1alpha1.ControllerInstallation, error)

CreateOrPatchControllerInstallation either creates the object or patches the existing one with the strategic merge patch type.

func CreateOrUpdate 

func CreateOrUpdate(ctx context.Context, c client.Client, obj runtime.Object, transform func() error) error

CreateTwoWayMergePatch creates a two way merge patch of the given objects. The two objects have to be pointers implementing the interfaces.

func GetLoadBalancerIngress 

func GetLoadBalancerIngress(ctx context.Context, client client.Client, namespace, name string) (string, error)

GetLoadBalancerIngress takes a context, a client, a namespace and a service name. It queries for a load balancer's technical name (ip address or hostname). It returns the value of the technical name whereby it always prefers the IP address (if given) over the hostname. It also returns the list of all load balancer ingresses.

func HasDeletionTimestamp 

func HasDeletionTimestamp(obj runtime.Object) (bool, error)

HasDeletionTimestamp checks if an object has a deletion timestamp

func HasMetaDataAnnotation

func Key 

func Key(namespaceOrName string, nameOpt ...string) client.ObjectKey

Key creates a new client.ObjectKey from the given parameters. There are only two ways to call this function:

  • If only namespaceOrName is set, then a client.ObjectKey with name set to namespaceOrName is returned.
  • If namespaceOrName and one nameOpt is given, then a client.ObjectKey with namespace set to namespaceOrName and name set to nameOpt[0] is returned.
