Package config provides decoupling between various configuration sources (etcd, files,...) and the pieces that actually care about them (loadbalancer, proxy). Config takes 1 or more configuration sources and allows for incremental (add/remove) and full replace (set) changes from each of the sources, then creates a union of the configuration and provides a unified view for both service handlers as well as endpoint handlers. There is no attempt to resolve conflicts of any sort. Basic idea is that each configuration source gets a channel from the Config service and pushes updates to it via that channel. Config then keeps track of incremental & replace changes and distributes them to listeners as appropriate.

Types

type EndpointSliceConfig

type EndpointSliceConfig struct {
	// contains filtered or unexported fields
}

EndpointSliceConfig tracks a set of endpoints configurations.

func NewEndpointSliceConfig

func NewEndpointSliceConfig(endpointSliceInformer discoveryinformers.EndpointSliceInformer, resyncPeriod time.Duration) *EndpointSliceConfig

NewEndpointSliceConfig creates a new EndpointSliceConfig.

func (*EndpointSliceConfig) RegisterEventHandler

func (c *EndpointSliceConfig) RegisterEventHandler(handler EndpointSliceHandler)

RegisterEventHandler registers a handler which is called on every endpoint slice change.

func (*EndpointSliceConfig) Run

func (c *EndpointSliceConfig) Run(stopCh <-chan struct{})

Run waits for cache synced and invokes handlers after syncing.

type EndpointSliceHandler

type EndpointSliceHandler interface {
	// OnEndpointSliceAdd is called whenever creation of new endpoint slice
	// object is observed.
	OnEndpointSliceAdd(endpointSlice *discovery.EndpointSlice)
	// OnEndpointSliceUpdate is called whenever modification of an existing
	// endpoint slice object is observed.
	OnEndpointSliceUpdate(oldEndpointSlice, newEndpointSlice *discovery.EndpointSlice)
	// OnEndpointSliceDelete is called whenever deletion of an existing
	// endpoint slice object is observed.
	OnEndpointSliceDelete(endpointSlice *discovery.EndpointSlice)
	// OnEndpointSlicesSynced is called once all the initial event handlers were
	// called and the state is fully propagated to local cache.
	OnEndpointSlicesSynced()
}

EndpointSliceHandler is an abstract interface of objects which receive notifications about endpoint slice object changes.

type EndpointsConfig

type EndpointsConfig struct {
	// contains filtered or unexported fields
}

EndpointsConfig tracks a set of endpoints configurations.

func NewEndpointsConfig

func NewEndpointsConfig(endpointsInformer coreinformers.EndpointsInformer, resyncPeriod time.Duration) *EndpointsConfig

NewEndpointsConfig creates a new EndpointsConfig.

func (*EndpointsConfig) RegisterEventHandler

func (c *EndpointsConfig) RegisterEventHandler(handler EndpointsHandler)

RegisterEventHandler registers a handler which is called on every endpoints change.

func (*EndpointsConfig) Run

func (c *EndpointsConfig) Run(stopCh <-chan struct{})

Run waits for cache synced and invokes handlers after syncing.

type EndpointsHandler

type EndpointsHandler interface {
	// OnEndpointsAdd is called whenever creation of new endpoints object
	// is observed.
	OnEndpointsAdd(endpoints *v1.Endpoints)
	// OnEndpointsUpdate is called whenever modification of an existing
	// endpoints object is observed.
	OnEndpointsUpdate(oldEndpoints, endpoints *v1.Endpoints)
	// OnEndpointsDelete is called whenever deletion of an existing endpoints
	// object is observed.
	OnEndpointsDelete(endpoints *v1.Endpoints)
	// OnEndpointsSynced is called once all the initial event handlers were
	// called and the state is fully propagated to local cache.
	OnEndpointsSynced()
}

EndpointsHandler is an abstract interface of objects which receive notifications about endpoints object changes.

type ServiceConfig

type ServiceConfig struct {
	// contains filtered or unexported fields
}

ServiceConfig tracks a set of service configurations.

func NewServiceConfig

func NewServiceConfig(serviceInformer coreinformers.ServiceInformer, resyncPeriod time.Duration) *ServiceConfig

NewServiceConfig creates a new ServiceConfig.

func (*ServiceConfig) RegisterEventHandler

func (c *ServiceConfig) RegisterEventHandler(handler ServiceHandler)

RegisterEventHandler registers a handler which is called on every service change.

func (*ServiceConfig) Run

func (c *ServiceConfig) Run(stopCh <-chan struct{})

Run waits for cache synced and invokes handlers after syncing.

type ServiceHandler

type ServiceHandler interface {
	// OnServiceAdd is called whenever creation of new service object
	// is observed.
	OnServiceAdd(service *v1.Service)
	// OnServiceUpdate is called whenever modification of an existing
	// service object is observed.
	OnServiceUpdate(oldService, service *v1.Service)
	// OnServiceDelete is called whenever deletion of an existing service
	// object is observed.
	OnServiceDelete(service *v1.Service)
	// OnServiceSynced is called once all the initial event handlers were
	// called and the state is fully propagated to local cache.
	OnServiceSynced()
}

ServiceHandler is an abstract interface of objects which receive notifications about service object changes.
