**Mounted Secrets are updated automatically**
When a secret being already consumed in a volume is updated, projected keys are eventually updated as well.
The update time depends on the kubelet syncing period.
Kubelet is checking whether the mounted secret is fresh on every periodic sync.
However, it is using its local ttl-based cache for getting the current value of the secret.
As a result, the total delay from the moment when the secret is updated to the moment when new keys are
projected to the pod can be as long as kubelet sync period + ttl of secrets cache in kubelet.
