# Volumes

In Kubernetes, a volume is an abstraction of a file system made available to applications. In Portainer, you can manage the volumes deployed by your applications within your cluster.

Volumes and storage classes can be added [using a manifest](/sts/user/kubernetes/applications/manifest/create.md) or a [helm chart](/sts/user/kubernetes/applications/manifest/helm.md) by clicking **Create from code.**

## Persistent volume claims
