Functions

func CleanupClusterResource

func CleanupClusterResource(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 DockercfgSecretCreator

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

func KubermaticProxyEnvironmentVars

func KubermaticProxyEnvironmentVars(p *kubermaticv1.KubermaticProxyConfiguration) (result []corev1.EnvVar)

KubermaticProxyEnvironmentVars returns ProxySettings from Kubermatic configuration as env vars.

func NamespaceCreator

func NamespaceCreator(cfg *kubermaticv1.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 SeedAdmissionServiceCreator

func SeedAdmissionServiceCreator(cfg *kubermaticv1.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 *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) reconciling.NamedValidatingWebhookConfigurationCreatorGetter

func SeedAdmissionWebhookName

func SeedAdmissionWebhookName(cfg *kubermaticv1.KubermaticConfiguration) string

func SeedProxyEnvironmentVars

func SeedProxyEnvironmentVars(p *kubermaticv1.ProxySettings) (result []corev1.EnvVar)

SeedProxyEnvironmentVars returns ProxySettings from Seed as env vars.

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

func WebhookCABundle(cfg *kubermaticv1.KubermaticConfiguration, client ctrlruntimeclient.Client) ([]byte, error)

func WebhookServingCASecretCreator

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

func WebhookServingCertSecretCreator

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