Bounded code example (external data; do not execute automatically):
```text
When you have a ConfigMap that is mapped into a running Pod using either a
`configMap` volume or a `projected` volume, and you update that ConfigMap,
the running Pod sees the update almost immediately.
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.

{{&lt; alert color="info" title="Note" &gt;}}
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.
Also check [Mounted ConfigMaps are updated automatically](/docs/tasks/configure-pod-container/configure-pod-configmap/#mounted-configmaps-are-updated-automatically).
{{&lt; /alert &gt;}}
