Functions

func BundleDeploymentProvisionerFilter

func BundleDeploymentProvisionerFilter(provisionerClassName string) predicate.Predicate

func BundleLabels

func BundleLabels(bundleName string) map[string]string

func BundleProvisionerFilter

func BundleProvisionerFilter(provisionerClassName string) predicate.Predicate

func CheckDesiredBundleTemplate

func CheckDesiredBundleTemplate(existingBundle *rukpakv1alpha1.Bundle, desiredBundle *rukpakv1alpha1.BundleTemplate) bool

CheckDesiredBundleTemplate is responsible for determining whether the existingBundle hash is equal to the desiredBundle Bundle template hash.

func CheckExistingBundlesMatchesTemplate

func CheckExistingBundlesMatchesTemplate(existingBundles *rukpakv1alpha1.BundleList, desiredBundleTemplate *rukpakv1alpha1.BundleTemplate) *rukpakv1alpha1.Bundle

CheckExistingBundlesMatchesTemplate evaluates whether the existing list of Bundle objects match the desired Bundle template that's specified in a BundleDeployment object. If a match is found, that Bundle object is returned, so callers are responsible for nil checking the result.

func CreateOrRecreate

func CreateOrRecreate(ctx context.Context, cl client.Client, obj client.Object, f controllerutil.MutateFn) (controllerutil.OperationResult, error)

func DeepHashObject

func DeepHashObject(hasher hash.Hash, objectToWrite interface{})

DeepHashObject writes specified object to hash using the spew library which follows pointers and prints actual values of the nested objects ensuring the hash does not change when a pointer changes. From https://github.com/operator-framework/operator-lifecycle-manager/blob/master/pkg/lib/kubernetes/pkg/util/hash/hash.go

func GenerateBundleName

func GenerateBundleName(bdName, hash string) string

func GenerateTemplateHash

func GenerateTemplateHash(template *rukpakv1alpha1.BundleTemplate) string

func GetBundlesForBundleDeploymentSelector

func GetBundlesForBundleDeploymentSelector(ctx context.Context, c client.Client, bd *rukpakv1alpha1.BundleDeployment) (*rukpakv1alpha1.BundleList, error)

GetBundlesForBundleDeploymentSelector is responsible for returning a list of Bundle resource that exist on cluster that match the label selector specified in the BD parameter's spec.Selector field.

func LoadCertPool

func LoadCertPool(certFile string) (*x509.CertPool, error)

func MapBundleDeploymentToBundles

func MapBundleDeploymentToBundles(ctx context.Context, c client.Client, bd rukpakv1alpha1.BundleDeployment) *rukpakv1alpha1.BundleList

func MapBundleToBundleDeploymentHandler

func MapBundleToBundleDeploymentHandler(cl client.Client, log logr.Logger) handler.MapFunc

func MapBundleToBundleDeployments

func MapBundleToBundleDeployments(ctx context.Context, c client.Client, b rukpakv1alpha1.Bundle) []*rukpakv1alpha1.BundleDeployment

func MapOwneeToOwnerProvisionerHandler

func MapOwneeToOwnerProvisionerHandler(ctx context.Context, cl client.Client, log logr.Logger, provisionerClassName string, owner ProvisionerClassNameGetter) handler.EventHandler

MapOwneeToOwnerProvisionerHandler is a handler implementation that finds an owner reference in the event object that references the provided owner. If a reference for the provided owner is found AND that owner's provisioner class name matches the provided provisionerClassName, this handler enqueues a request for that owner to be reconciled.

func MergeMaps

func MergeMaps(maps ...map[string]string) map[string]string

func NewBundleDeploymentLabelSelector

func NewBundleDeploymentLabelSelector(bd *rukpakv1alpha1.BundleDeployment) labels.Selector

NewBundleDeploymentLabelSelector is responsible for constructing a label.Selector for any underlying resources that are associated with the BundleDeployment parameter.

func NewBundleLabelSelector

func NewBundleLabelSelector(bundle *rukpakv1alpha1.Bundle) labels.Selector

NewBundleLabelSelector is responsible for constructing a label.Selector for any underlying resources that are associated with the Bundle parameter.

func PodName

func PodName(provisionerName, bundleName string) string

func PodNamespace

func PodNamespace(defaultNamespace string) string

GetPodNamespace checks whether the controller is running in a Pod vs. being run locally by inspecting the namespace file that gets mounted automatically for Pods at runtime. If that file doesn't exist, then return the @defaultNamespace namespace parameter.

func SortBundlesByCreation

func SortBundlesByCreation(bundles *rukpakv1alpha1.BundleList)

SortBundlesByCreation sorts a BundleList's items by it's metadata.CreationTimestamp value.

Types

type ProvisionerClassNameGetter

type ProvisionerClassNameGetter interface {
	client.Object
	ProvisionerClassName() string
}
