Functions

func CleanupClusterResource 

func CleanupClusterResource(client ctrlruntimeclient.Client, obj runtime.Object, name string) error

CleanupClusterResource attempts to find a cluster-wide resource and deletes it if it was found. If no resource with the given name exists, nil is returned.

func CreateUpdatesYAML 

func CreateUpdatesYAML(config *operatorv1alpha1.KubermaticVersionsConfiguration) (string, error)

func CreateVersionsYAML 

func CreateVersionsYAML(config *operatorv1alpha1.KubermaticVersionsConfiguration) (string, error)

func DefaultConfiguration 

func DefaultConfiguration(config *operatorv1alpha1.KubermaticConfiguration, logger *zap.SugaredLogger) (*operatorv1alpha1.KubermaticConfiguration, error)

func DefaultSeed 

func DefaultSeed(seed *kubermaticv1.Seed, logger *zap.SugaredLogger) (*kubermaticv1.Seed, error)

func DexCASecretCreator 

func DexCASecretCreator(cfg *operatorv1alpha1.KubermaticConfiguration) reconciling.NamedSecretCreatorGetter

func DockercfgSecretCreator 

func DockercfgSecretCreator(cfg *operatorv1alpha1.KubermaticConfiguration) reconciling.NamedSecretCreatorGetter

func ExtraFilesSecretCreator 

func ExtraFilesSecretCreator(cfg *operatorv1alpha1.KubermaticConfiguration) reconciling.NamedSecretCreatorGetter

func NamespaceCreator 

func NamespaceCreator(cfg *operatorv1alpha1.KubermaticConfiguration) reconciling.NamedNamespaceCreatorGetter

func OwnershipModifierFactory 

func OwnershipModifierFactory(owner metav1.Object, scheme *runtime.Scheme) reconciling.ObjectModifier

OwnershipModifierFactory is generating a new ObjectModifier that wraps an ObjectCreator and takes care of applying the ownership and other labels for all managed objects.

func ProxyEnvironmentVars 

func ProxyEnvironmentVars(cfg *operatorv1alpha1.KubermaticConfiguration) []corev1.EnvVar

func SeedAdmissionServiceCreator 

func SeedAdmissionServiceCreator(cfg *operatorv1alpha1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedServiceCreatorGetter

SeedAdmissionServiceCreator creates the Service for the Seed Admission webhook. This service is created on master and seed clusters, because on masters the original copy of a Seed is validated, and on seed clusters the synced copy is validated (synced by the seed-sync controller).

func SeedAdmissionWebhookCreator 

func SeedAdmissionWebhookCreator(cfg *operatorv1alpha1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedValidatingWebhookConfigurationCreatorGetter

func SeedAdmissionWebhookName 

func SeedAdmissionWebhookName(cfg *operatorv1alpha1.KubermaticConfiguration) string

func StringifyFeatureGates 

func StringifyFeatureGates(cfg *operatorv1alpha1.KubermaticConfiguration) string

StringifyFeatureGates takes a set of enabled features and returns a comma-separated key=value list like "featureA=true,featureB=true,...".

func VolumeRevisionLabelsModifierFactory 

func VolumeRevisionLabelsModifierFactory(ctx context.Context, client ctrlruntimeclient.Client) reconciling.ObjectModifier

VolumeRevisionLabelsModifierFactory scans volume mounts for pod templates for ConfigMaps and Secrets and will then put new labels for these mounts onto the pod template, causing restarts when the volumes changed.

func WebhookCABundle added in v2.16.3 

func WebhookCABundle(cfg *operatorv1alpha1.KubermaticConfiguration, client ctrlruntimeclient.Client) ([]byte, error)

func WebhookServingCASecretCreator added in v2.16.3 

func WebhookServingCASecretCreator(cfg *operatorv1alpha1.KubermaticConfiguration) reconciling.NamedSecretCreatorGetter

func WebhookServingCertSecretCreator added in v2.16.3 

func WebhookServingCertSecretCreator(cfg *operatorv1alpha1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedSecretCreatorGetter
