# Certificate Rotation
By default, certificates in K3s expire in 12 months.
If the certificates are expired or have fewer than 90 days remaining before they expire, the certificates are rotated when K3s is restarted.
# Auto-Deploying Manifests
Any file found in `/var/lib/rancher/k3s/server/manifests` will automatically be deployed to Kubernetes in a manner similar to `kubectl apply`.
