ArangoLocalStorage Custom Resource
The ArangoDB Storage Operator creates and maintains ArangoDB
storage resources in a Kubernetes cluster, given a storage specification.
This storage specification is a CustomResource
following
a 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
calledmy-local-ssd
- the dynamic provisioning of PersistentVolume’s with
a local volume on a node where the local volume starts
in a sub-directory of
/mnt/big-ssd-disk
. - the dynamic cleanup of PersistentVolume’s (created by the operator) after one is released.
The provisioned volumes will have a capacity that matches the requested capacity of volume claims.

This setting specifies if the created StorageClass
will
be marked as default storage class. (default is false
