ArangoLocalStorage Custom Resource

The ArangoDB Storage Operator creates and maintains ArangoDBstorage resources in a Kubernetes cluster, given a storage specification.This storage specification is a CustomResource followinga CustomResourceDefinition created by the operator.

Example minimal storage definition:

apiVersion: "storage.arangodb.com/v1alpha"
kind: "ArangoLocalStorage"
metadata:
  name: "example-arangodb-storage"
spec:
  storageClass:
    name: my-local-ssd
  localPath:
  - /mnt/big-ssd-disk

This definition results in:

• a StorageClass called my-local-ssd
• the dynamic provisioning of PersistentVolume’s witha local volume on a node where the local volume startsin a sub-directory of /mnt/big-ssd-disk.
• the dynamic cleanup of PersistentVolume’s (created bythe operator) after one is released.

The provisioned volumes will have a capacity that matchesthe requested capacity of volume claims.
