func EqualRemoteConfigSources

func EqualRemoteConfigSources(a, b RemoteConfigSource) bool

EqualRemoteConfigSources is a helper for comparing remote config sources by comparing the underlying API objects for semantic equality.


type Payload added in v1.11.0

type Payload interface {
	// UID returns a globally unique (space and time) identifier for the payload.
	// The return value is guaranteed non-empty.
	UID() string

	// ResourceVersion returns a resource version for the payload.
	// The return value is guaranteed non-empty.
	ResourceVersion() string

	// Files returns a map of filenames to file contents.
	Files() map[string]string
	// contains filtered or unexported methods

Payload represents a local copy of a config source (payload) object

func NewConfigMapPayload added in v1.11.0

func NewConfigMapPayload(cm *apiv1.ConfigMap) (Payload, error)

NewConfigMapPayload constructs a Payload backed by a ConfigMap, which must have a non-empty UID

type RemoteConfigSource

type RemoteConfigSource interface {
	// KubeletFilename returns the name of the Kubelet config file as it should appear in the keys of Payload.Files()
	KubeletFilename() string

	// APIPath returns the API path to the remote resource.
	APIPath() string

	// UID returns the globally unique identifier for the most recently downloaded payload targeted by the source.
	UID() string

	// ResourceVersion returns the resource version of the most recently downloaded payload targeted by the source.
	ResourceVersion() string

	// Download downloads the remote config source's target object and returns a Payload backed by the object,
	// or a sanitized failure reason and error if the download fails.
	// Download takes an optional store as an argument. If provided, Download will check this store for the
	// target object prior to contacting the API server.
	// Download updates the local UID and ResourceVersion tracked by this source, based on the downloaded payload.
	Download(client clientset.Interface, store cache.Store) (Payload, string, error)

	// Informer returns an informer that can be used to detect changes to the remote config source
	Informer(client clientset.Interface, handler cache.ResourceEventHandlerFuncs) cache.SharedInformer

	// Encode returns a []byte representation of the object behind the RemoteConfigSource
	Encode() ([]byte, error)

	// NodeConfigSource returns a copy of the underlying apiv1.NodeConfigSource object.
	// All RemoteConfigSources are expected to be backed by a NodeConfigSource,
	// though the convenience methods on the interface will target the source
	// type that was detected in a call to NewRemoteConfigSource.
	NodeConfigSource() *apiv1.NodeConfigSource

RemoteConfigSource represents a remote config source object that can be downloaded as a Checkpoint

func DecodeRemoteConfigSource

func DecodeRemoteConfigSource(data []byte) (RemoteConfigSource, error)

DecodeRemoteConfigSource is a helper for using the apimachinery to decode serialized RemoteConfigSources; e.g. the metadata stored by checkpoint/store/fsstore.go

func NewRemoteConfigSource

func NewRemoteConfigSource(source *apiv1.NodeConfigSource) (RemoteConfigSource, string, error)

NewRemoteConfigSource constructs a RemoteConfigSource from a v1/NodeConfigSource object You should only call this with a non-nil config source. Note that the API server validates Node.Spec.ConfigSource.
