Functions

func ApplicationDefinitionValidatingWebhookConfigurationCreator added in v2.21.0 

func ApplicationDefinitionValidatingWebhookConfigurationCreator(ctx context.Context, cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedValidatingWebhookConfigurationCreatorGetter

func CRDCreator added in v2.21.0 

func CRDCreator(crd *apiextensionsv1.CustomResourceDefinition, log *zap.SugaredLogger, versions kubermaticversion.Versions) reconciling.NamedCustomResourceDefinitionCreatorGetter

CRDCreator will reconcile a CRD, but only if the existing CRD is older or the same version (i.e. this function will never downgrade a CRD). Up- and downgrading is only defined for KKP CRDs which have a version annotation.

func CleanupClusterResource 

func CleanupClusterResource(ctx context.Context, client ctrlruntimeclient.Client, obj ctrlruntimeclient.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 CleanupWebhookServices added in v2.21.0 

func CleanupWebhookServices(ctx context.Context, client ctrlruntimeclient.Client, logger *zap.SugaredLogger, namespace string)

CleanupWebhookServices removes the unused webhook services. It's here because we need to exact same logic on master and seed clusters.

func DeleteObject added in v2.21.0 

func DeleteObject(ctx context.Context, client ctrlruntimeclient.Client, name, namespace string, obj ctrlruntimeclient.Object) error

func DeleteService added in v2.21.0 

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

func DockercfgSecretCreator 

func DockercfgSecretCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedSecretCreatorGetter

func KubermaticConfigurationAdmissionWebhookCreator added in v2.21.0 

func KubermaticConfigurationAdmissionWebhookCreator(ctx context.Context, cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedValidatingWebhookConfigurationCreatorGetter

func KubermaticConfigurationAdmissionWebhookName added in v2.21.0 

func KubermaticConfigurationAdmissionWebhookName(cfg *kubermaticv1.KubermaticConfiguration) string

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 *kubermaticv1.KubermaticConfiguration) []corev1.EnvVar

func SeedAdmissionWebhookCreator 

func SeedAdmissionWebhookCreator(ctx context.Context, cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedValidatingWebhookConfigurationCreatorGetter

func SeedAdmissionWebhookName 

func SeedAdmissionWebhookName(cfg *kubermaticv1.KubermaticConfiguration) string

func StringifyFeatureGates 

func StringifyFeatureGates(cfg *kubermaticv1.KubermaticConfiguration) string

StringifyFeatureGates takes a set of enabled features and returns a comma-separated key=value list like "featureA=true,featureB=true,...". The list of feature gates is sorted, so the output of this function is stable.

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(ctx context.Context, cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) ([]byte, error)

func WebhookClusterRoleBindingCreator added in v2.21.0 

func WebhookClusterRoleBindingCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedClusterRoleBindingCreatorGetter

func WebhookClusterRoleBindingName added in v2.21.0 

func WebhookClusterRoleBindingName(cfg *kubermaticv1.KubermaticConfiguration) string

func WebhookClusterRoleCreator added in v2.21.0 

func WebhookClusterRoleCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedClusterRoleCreatorGetter

func WebhookClusterRoleName added in v2.21.0 

func WebhookClusterRoleName(cfg *kubermaticv1.KubermaticConfiguration) string

func WebhookDeploymentCreator added in v2.21.0 

func WebhookDeploymentCreator(cfg *kubermaticv1.KubermaticConfiguration, versions kubermatic.Versions, seed *kubermaticv1.Seed, removeSeed bool) reconciling.NamedDeploymentCreatorGetter

WebhookDeploymentCreator returns a DeploymentCreator for the Kubermatic webhook. The removeSeed flag should always be set to false, except for during seed cleanup. This is important because on shared master+seed clusters, when the Seed is removed, the -seed-name flag must be gone. But because the creator is careful to not accidentally remove the flag (so that the master-operator does not wipe the seed-operator's work), a separate parameter is needed to indicate that yes, we want to in fact remove the flag.

func WebhookRoleBindingCreator added in v2.21.0 

func WebhookRoleBindingCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedRoleBindingCreatorGetter

func WebhookRoleCreator added in v2.21.0 

func WebhookRoleCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedRoleCreatorGetter

func WebhookServiceAccountCreator added in v2.21.0 

func WebhookServiceAccountCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedServiceAccountCreatorGetter

func WebhookServiceCreator added in v2.21.0 

func WebhookServiceCreator(cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedServiceCreatorGetter

WebhookServiceCreator creates the Service for all KKP webhooks.

func WebhookServingCASecretCreator added in v2.16.3 

func WebhookServingCASecretCreator(cfg *kubermaticv1.KubermaticConfiguration) reconciling.NamedSecretCreatorGetter

func WebhookServingCertSecretCreator added in v2.16.3 

func WebhookServingCertSecretCreator(ctx context.Context, cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedSecretCreatorGetter
