NewVirtualManager is used to create a new virtual manager

Functions

func ApplyCoreDNS

func ApplyCoreDNS(controllerContext *config.ControllerContext)

func CheckUsingHelm

func CheckUsingHelm(ctx context.Context, client kubernetes.Interface, name, namespace, distro string, backingStoreType vclusterconfig.StoreType) (bool, error)

CheckUsingHelm fetches the previous release revision and its computed values, and then reconstructs the distro and storage settings.

func CheckUsingHeuristic

func CheckUsingHeuristic(distro string) (bool, error)

CheckUsingHeuristic checks for known file path indicating the existence of a previous distro.

It checks for the existence of the default K3s token path or the K0s data directory.

func CheckUsingSecretAnnotation

func CheckUsingSecretAnnotation(ctx context.Context, client kubernetes.Interface, name, namespace, distro string, backingStoreType vclusterconfig.StoreType) (bool, error)

CheckUsingSecretAnnotation checks for backend store and distro changes using annotations on the vCluster's secret annotations. Returns true, if both annotations are set and the check was successful, otherwise false.

func CreateVClusterKubeConfig

func CreateVClusterKubeConfig(config *clientcmdapi.Config, options *config.VirtualClusterConfig) (*clientcmdapi.Config, error)

func EnsureBackingStoreChanges

func EnsureBackingStoreChanges(ctx context.Context, client kubernetes.Interface, name, namespace, distro string, backingStoreType vclusterconfig.StoreType) error

EnsureBackingStoreChanges ensures that only a certain set of allowed changes to the backing store and distro occur.

func GenerateCerts

func GenerateCerts(ctx context.Context, currentNamespaceClient kubernetes.Interface, vClusterName, currentNamespace, serviceCIDR, certificatesDir string, options *config.VirtualClusterConfig) error

func InitAndValidateConfig

func InitAndValidateConfig(ctx context.Context, vConfig *config.VirtualClusterConfig) error

func Initialize

func Initialize(ctx context.Context, options *config.VirtualClusterConfig) error

Initialize creates the required secrets and configmaps for the control plane to start

func NewControllerContext

func NewControllerContext(ctx context.Context, options *config.VirtualClusterConfig) (*config.ControllerContext, error)

NewControllerContext builds the controller context we can use to start the syncer

func RegisterOrDeregisterAPIService

func RegisterOrDeregisterAPIService(ctx *config.ControllerContext)

func SetGlobalOwner

func SetGlobalOwner(ctx context.Context, vConfig *config.VirtualClusterConfig) error

SetGlobalOwner fetches the owning service and populates in translate.Owner if: the vcluster is configured to setOwner is, and if the currentNamespace == targetNamespace (because cross namespace owner refs don't work).

func StartControllers

func StartControllers(controllerContext *config.ControllerContext) error

func StartManagers

func StartManagers(controllerContext *config.ControllerContext, syncers []syncertypes.Object) error

func StartProxy

func StartProxy(ctx *config.ControllerContext) error

func SyncKubernetesService

func SyncKubernetesService(ctx *config.ControllerContext) error

func UpdateSecretWithK0sCerts

func UpdateSecretWithK0sCerts(
	ctx context.Context,
	currentNamespaceClient kubernetes.Interface,
	currentNamespace, vClusterName string,
) error

func WriteKubeConfigToSecret

func WriteKubeConfigToSecret(ctx context.Context, currentNamespace string, currentNamespaceClient client.Client, options *config.VirtualClusterConfig, syncerConfig *clientcmdapi.Config) error
