Tanzu Community Edition


Local Path Storage - v0.0.20

This package provides local path node storage and primarily supports RWO AccessMode. It utilizes the Kubernetes Local Persistent Volume feature and in Tanzu Community Edition, it is primarily intended for use with Docker, although it will work with any infrastructure provider or package where persistent storage is needed.

This package also provides a StorageClass. If there is no StorageClass already installed on the cluster, then the StorageClass provided in this package will automatically be made the default. Otherwise, the storageclass.kubernetes.io/is-default-class may need to be modified.


The local-path-storage binds to a single host node and is not intended to dynamically change hosts. Therefore, a PVC can only be used by the node that creates it. This can lead to unintended data loss when scaling or when pods roll from one node to another. Further, it can make scheduling difficult since applications are “tied” to the node that created it’s PV.

Further, local-path-storage does not enforce capacity limitations and may, possibly overwhelm the local node’s disc capacity.

See the local-path-storage GitHub for further documentation and configuration options.

Note: The local path storage provides a config map that may be modified after installation. This includes a config.json that can be used to further configure the storage provider. Additionally, setup and teardown scripts are defined in the config map and are used in the lifecycle of persistent volumes. The local-path-storage pods will dynamically reload the config map upon configuration without need to reapply the deployment.

Usage Examples

A StorageClass is required in order to use PVCs and store data (which is necessary for services like Prometheus). The local-path-storage provider enables local Docker clusters to store data locally. Using a local PVC with Docker lets a developer work quickly on their own workstation with Docker.

A local storage provider may also be used in special cases for caching, sharding data in distributed datastores, and other node failure tolerant storage models. Note that local storage providers are generally not suitable for most production use cases.
