Functions

func CreateCustomResourceDefinitionFromManifest

func CreateCustomResourceDefinitionFromManifest(ctx context.Context, embedFiles embed.FS, fileName string) error

CreateCustomResourceDefinitionFromManifest creates custom resource definition spec from manifest file.

func CreateCustomResourceDefinitionFromSpec

func CreateCustomResourceDefinitionFromSpec(ctx context.Context, crdName string, crdSingular string, crdPlural string,
	crdKind string, crdGroup string, crdVersion string, crdScope apiextensionsv1.ResourceScope) error

CreateCustomResourceDefinitionFromSpec creates the custom resource definition from given spec. If there is error, function will do the clean up.

func CreateKubernetesClientFromConfig

func CreateKubernetesClientFromConfig(kubeConfigPath string) (clientset.Interface, error)

CreateKubernetesClientFromConfig creaates a newk8s client from given kubeConfig file.

func GetDynamicInformer

func GetDynamicInformer(ctx context.Context, crdGroup, crdVersion, crdName, namespace string,
	cfg *restclient.Config, isInCluster bool) (informers.GenericInformer, error)

GetDynamicInformer returns informer for specified CRD group, version, name and namespace.

isInCluster should be set to true if the resource is present in the same cluster, otherwise set false if the resource is present in the supervisor cluster in TKG flavor.

Takes an input configuration to create a client for the dynamic informer. If isInCluster is set to true, the config contains credentials to the in cluster API server. If isInCluster is set to false, config contains credentials to the supervisor cluster.

func GetKubeConfig

func GetKubeConfig(ctx context.Context) (*restclient.Config, error)

GetKubeConfig helps retrieve Kubernetes Config.

func GetNodeVMUUID

func GetNodeVMUUID(ctx context.Context, k8sclient clientset.Interface, nodeName string) (string, error)

GetNodeVMUUID returns vSphere VM UUID set by CCM on the Kubernetes Node.

func GetRestClientConfigForSupervisor

func GetRestClientConfigForSupervisor(ctx context.Context, endpoint string, port string) *restclient.Config

GetRestClientConfigForSupervisor returns restclient config for given endpoint, port, certificate and token.

func NewCSINodeTopologyWatcher

func NewCSINodeTopologyWatcher(ctx context.Context, config *restclient.Config) (*cache.ListWatch, error)

NewCSINodeTopologyWatcher creates a new ListWatch for CSINodeTopology objects given rest client config.

func NewClient

func NewClient(ctx context.Context) (clientset.Interface, error)

NewClient creates a newk8s client based on a service account.

func NewClientForGroup

func NewClientForGroup(ctx context.Context, config *restclient.Config, groupName string) (client.Client, error)

NewClientForGroup creates a new controller-runtime client for a new scheme. The input Group is added to this scheme.

func NewCnsFileAccessConfigWatcher

func NewCnsFileAccessConfigWatcher(ctx context.Context, config *restclient.Config,
	namespace string) (*cache.ListWatch, error)

NewCnsFileAccessConfigWatcher creates a new ListWatch for VirtualMachines given rest client config.

func NewSnapshotterClient

func NewSnapshotterClient(ctx context.Context) (snapshotterClientSet.Interface, error)

NewSnapshotterClient creates a new external-snapshotter client based on a service account.

func NewSupervisorClient

func NewSupervisorClient(ctx context.Context, config *restclient.Config) (clientset.Interface, error)

NewSupervisorClient creates a new supervisor client for given restClient config.

func NewVirtualMachineWatcher

func NewVirtualMachineWatcher(ctx context.Context, config *restclient.Config,
	namespace string) (*cache.ListWatch, error)

NewVirtualMachineWatcher creates a new ListWatch for VirtualMachines given rest client config.
