Types

type ConfigAccessor

type ConfigAccessor interface {
	ToEnvVars() []corev1.EnvVar
	LoggingConfig() *logging.Config
	MetricsConfig() *metrics.ExporterOptions
	TracingConfig() *tracingconfig.Config
}

type ConfigWatcher

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

ConfigWatcher keeps track of logging, metrics and tracing configurations by watching corresponding ConfigMaps.

func WatchConfigurations

func WatchConfigurations(loggingCtx context.Context, component string,
	cmw configmap.Watcher, opts ...configWatcherOption) *ConfigWatcher

WatchConfigurations returns a ConfigWatcher initialized with the given options. If no option is passed, the ConfigWatcher observes ConfigMaps for logging, metrics and tracing.

LoggingConfig returns the logging configuration from the ConfigWatcher.

func (*ConfigWatcher) MetricsConfig

func (cw *ConfigWatcher) MetricsConfig() *metrics.ExporterOptions

MetricsConfig returns the metrics configuration from the ConfigWatcher.

func (*ConfigWatcher) ToEnvVars

func (cw *ConfigWatcher) ToEnvVars() []corev1.EnvVar

ToEnvVars serializes the contents of the ConfigWatcher to individual environment variables.

func (*ConfigWatcher) TracingConfig

func (cw *ConfigWatcher) TracingConfig() *tracingconfig.Config

TracingConfig returns the tracing configuration from the ConfigWatcher.

type EmptyVarsGenerator

type EmptyVarsGenerator struct {
	ConfigAccessor
}

EmptyVarsGenerator generates empty env vars. Intended to be used in tests.

func (*EmptyVarsGenerator) ToEnvVars

func (g *EmptyVarsGenerator) ToEnvVars() []corev1.EnvVar
