### Mounted ConfigMaps are updated automatically
When a mounted ConfigMap is updated, the projected content is eventually updated too.
This applies in the case where an optionally referenced ConfigMap comes into existence after
a pod has started.
The kubelet checks whether the mounted ConfigMap is fresh on every periodic sync. However, it
uses its local TTL-based cache for getting the current value of the ConfigMap. As a result,
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 (1 minute by default) + TTL of
ConfigMaps cache (1 minute by default) in kubelet.
{{< note >}}
A container using a ConfigMap as a [subPath](/docs/concepts/storage/volumes/#using-subpath)
volume will not receive ConfigMap updates.
