#### Ingress

// For a given StorageClass, this describes the available capacity in a
// particular topology segment.  This can be used when considering where to
// instantiate new PersistentVolumes.
//
// For example this can express things like:
// - StorageClass "standard" has "1234 GiB" available in "topology.kubernetes.io/zone=us-east1"
// - StorageClass "localssd" has "10 GiB" available in "kubernetes.io/hostname=knode-abc123"
//

  // is considered to match if either object matches the selector. A null
  // object (oldObject in the case of create, or newObject in the case of
  // delete) or an object that cannot have labels (like a
  // DeploymentRollback or a PodProxyOptions object) is not considered to
  // match.
  // Use the object selector only if the webhook is opt-in, because end
  // users may skip the admission webhook by setting the labels.

to use the certificates written to disk, assuming the downtime is less than certificate expiration. This is why
the certificates are persisted to disk, rather than kept in memory like in the standard Kubernetes deployment.

## Certificate Rotation

The agent also handles rotating certificates near expiration. It does so by triggering a callback from the `SecretManager` to the SDS server
