Functions ¶
func RegisterConverterInitializer ¶ added in v0.2.0
func RegisterConverterInitializer(gvk metav1.GroupVersionKind, initFunc ConverterInitFunc)
RegisterConverterInitializer registers a converter initializer function for a specific gvk, the function will be called when the reporter manager is created. The function should return a converter for the gvk. If the function is called multiple times for the same gvk, the last one will be used.
func RegisterReporterInitializer ¶
func RegisterReporterInitializer(gvk metav1.GroupVersionKind, initFunc InitFunc)
Types ¶
type Converter ¶ added in v0.2.0
type Converter interface {
Convert(ctx context.Context, reportFields []*v1alpha1.ReportField) (*v1alpha1.ReportContent, error)
}
Converter converts the report fields to the format the reporter expects, for example, if the target crd version needs to be changed from v1alpha1 to v1, the converter can convert the v1alpha1's plugin report fields to v1 fields and report to the v1 reporter
type ConverterInitFunc ¶ added in v0.2.0
type ConverterInitFunc func(*client.GenericClientSet, *metaserver.MetaServer, metrics.MetricEmitter, *config.Configuration) (Converter, error)
ConverterInitFunc is the function to initialize a converter
type InitFunc ¶
type InitFunc func(*client.GenericClientSet, *metaserver.MetaServer, metrics.MetricEmitter, *config.Configuration) (Reporter, error)
InitFunc is used to initialize a particular reporter.
type Manager ¶
type Manager interface {
// PushContents gets ReportField list from report manager, the reporter implementation
// should be responsible for assembling and updating the specific object.
PushContents(ctx context.Context, responses map[string]*v1alpha1.GetReportContentResponse) error
// Run starts all the updaters registered in this Manager.
Run(ctx context.Context)
}
Manager indicates the way that resources are updated, and it is also responsible for other
func NewReporterManager ¶
func NewReporterManager(genericClient *client.GenericClientSet, metaServer *metaserver.MetaServer, emitter metrics.MetricEmitter, conf *config.Configuration, ) (Manager, error)
NewReporterManager is to create a reporter manager
type ManagerStub ¶
type ManagerStub struct {
// contains filtered or unexported fields
}
ManagerStub a reporter manager stub
func NewReporterManagerStub ¶
func NewReporterManagerStub() *ManagerStub
NewReporterManagerStub new a reporter stub
func (*ManagerStub) GetReportContentResponse ¶
func (s *ManagerStub) GetReportContentResponse(pluginName string) *v1alpha1.GetReportContentResponse
GetReportContentResponse get reporter content from local cache
func (*ManagerStub) PushContents ¶
func (s *ManagerStub) PushContents(_ context.Context, responses map[string]*v1alpha1.GetReportContentResponse) error
PushContents store response to local cache
func (*ManagerStub) Run ¶
func (s *ManagerStub) Run(context.Context)
Run start the reporter manager stub
type Reporter ¶
type Reporter interface {
// Update receives ReportField list from report manager, the reporter implementation
// should be responsible for assembling and updating the specific object
// todo: consider whether we should perform real update actions asynchronously
Update(ctx context.Context, fields []*v1alpha1.ReportField) error
// Run starts the syncing logic of reporter
Run(ctx context.Context)
}
Reporter use to update specific kind crd
type Stub ¶
type Stub struct {
// contains filtered or unexported fields
}
func NewReporterStub ¶
func NewReporterStub() *Stub
func (*Stub) GetReportedFields ¶
func (s *Stub) GetReportedFields() []*v1alpha1.ReportField
GetReportedFields get current fields just for test
