Types ¶
type HealthHandler ¶
type HealthHandler struct {
// contains filtered or unexported fields
}
HealthHandler is a http.Handler that is used for the lifeness probe.
func (HealthHandler) ServeHTTP ¶
func (h HealthHandler) ServeHTTP(w http.ResponseWriter, r *http.Request)
ServeHTTP reponds 200, when all services are healhy. Otherwise it responds with 503.
type Healthier ¶
type Healthier interface {
Healthy() bool
}
Healthier is a simple interface, that can easily be implemented by all critical services. It is used to indicate their health statuses.
type MainLoop ¶
type MainLoop struct {
// contains filtered or unexported fields
}
MainLoop does the actual node-drainer actions. When any client cache changes, it starts a new update loop and checks whether an action is required.
func NewMainLoop ¶
func NewMainLoop(collectors collectors.Collectors) *MainLoop
NewMainLoop initializes a MainLoop.
