Types

type Adapter

type Adapter interface {
	Start(stopCh <-chan struct{}) error
}

type AdapterConstructor

type AdapterConstructor func(ctx context.Context, env EnvConfigAccessor, client cloudevents.Client, reporter source.StatsReporter) Adapter

type EnvConfig

type EnvConfig struct {
	// SinkURI is the URI messages will be forwarded to.
	// DEPRECATED: use K_SINK
	SinkURI string `envconfig:"SINK_URI"`

	// Sink is the URI messages will be sent.
	Sink string `envconfig:"K_SINK"`

	// Environment variable containing the namespace of the adapter.
	Namespace string `envconfig:"NAMESPACE" required:"true"`

	// MetricsConfigJson is a json string of metrics.ExporterOptions.
	// This is used to configure the metrics exporter options,
	// the config is stored in a config map inside the controllers
	// namespace and copied here.
	MetricsConfigJson string `envconfig:"K_METRICS_CONFIG" required:"true"`

	// LoggingConfigJson is a json string of logging.Config.
	// This is used to configure the logging config, the config is stored in
	// a config map inside the controllers namespace and copied here.
	LoggingConfigJson string `envconfig:"K_LOGGING_CONFIG" required:"true"`
}

EnvConfig is the minimal set of configuration parameters source adapters should support.
