Functions

func KubeDecoratorProvider

func KubeDecoratorProvider(_ context.Context, cfg KubernetesDecorator) (node.MiddleFunc[[]request.Span, []request.Span], error)

func RoutesProvider

func RoutesProvider(_ context.Context, rc *RoutesConfig) (node.MiddleFunc[[]request.Span, []request.Span], error)

Types

type KubeEnableFlag

type KubeEnableFlag string

type KubernetesDecorator

type KubernetesDecorator struct {
	Enable KubeEnableFlag `yaml:"enable" env:"KUBE_METADATA_ENABLE"`
	// KubeconfigPath is optional. If unset, it will look in the usual location.
	KubeconfigPath string `yaml:"kubeconfig_path" env:"KUBE_METADATA_KUBECONFIG_PATH"`

	InformersSyncTimeout time.Duration `yaml:"informers_sync_timeout" env:"KUBE_INFORMERS_SYNC_TIMEOUT"`
}

func (KubernetesDecorator) Enabled

func (d KubernetesDecorator) Enabled() bool

type RoutesConfig

type RoutesConfig struct {
	// Unmatch specifies what to do when a route pattern is not matched
	Unmatch UnmatchType `yaml:"unmatch"`
	// Patterns of the paths that will match to a route
	Patterns []string `yaml:"patterns"`
}

RoutesConfig allows grouping URLs sharing a given pattern.

type UnmatchType

type UnmatchType string

UnmatchType defines which actions to do when a route pattern is not recognized
