	GetAllRoutes() ([]LogRoute, error)
	EmitNewRoute(route LogRoute) error
	EmitRemoveRoute(route LogRoute) error
	Writable() bool
	Close() error
}

Datasource describes an interface for querying and listening for routes

func FindDataSources added in v0.0.64 

func FindDataSources(useKubernetes bool, kubeConfig string, usePostgres bool, databaseURL string) ([]DataSource, error)

FindDataSources finds what datasources may be availabl and returns instantiated objects

type KubernetesDataSource 

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

KubernetesDataSource uses kubernetes as a datasource for routes by listening to annotations

func CreateKubernetesDataSource 

func CreateKubernetesDataSource(kube kubernetes.Interface, checkPermissions bool) (*KubernetesDataSource, error)

CreateKubernetesDataSource creates a new kubernetes data source from a kube client

func (*KubernetesDataSource) AddRoute 

func (kds *KubernetesDataSource) AddRoute() chan LogRoute

AddRoute returns a channel where new routes are published to

func (*KubernetesDataSource) Close 

func (kds *KubernetesDataSource) Close() error

Close closes the data sources

func (*KubernetesDataSource) EmitNewRoute added in v0.0.64 

func (kds *KubernetesDataSource) EmitNewRoute(route LogRoute) error

EmitNewRoute always returns an error as this datasource is not currently writable.

func (*KubernetesDataSource) EmitRemoveRoute added in v0.0.64 

func (kds *KubernetesDataSource) EmitRemoveRoute(route LogRoute) error

EmitRemoveRoute always returns an error as this datasource is not currently writable.

type Listener 

type Listener interface {
	Close() error
	Listen(string) error
	NotificationChannel() <-chan *pq.Notification
	Ping() error
}

This normally isnt needed but in order to pass in a fake listener for testing we need this.

type LogRoute 

type LogRoute struct {
	Endpoint string
	Hostname string
	Tag      string
	// contains filtered or unexported fields
}

LogRoute describes a structure for routes from Hostname -> Endpoint
