However, your application only sees the change if it is written to either poll for changes, or watch for file updates. An application that loads its configuration once at startup will not notice a change. {{< alert color="info" title="Note" >}} The total delay from the moment when the ConfigMap is updated to the moment when new keys are projected to the Pod can be as long as kubelet sync period.
