PLEASE NOTE: This document applies to an unreleased version of Rook. It is strongly recommended that you only use official releases of Rook, as unreleased versions are subject to changes and incompatibilities that will not be supported in the official releases.
If you are using an official release version of Rook, you should refer to the documentation for your specific version.Documentation for other releases can be found by using the version selector in the bottom left of any doc page.
Minio Object Store CRD
Minio object stores can be created and configured using the
objectstores.minio.rook.io custom resource definition (CRD). Complete instructions can be found in the Rook Minio Documentation.

Minio Specific Settings
The settings below are specific to Minio object stores:
credentials: This accepts the
namespacestrings of an existing Secret to specify the access credentials for the object store.
storageAmount: The size of the volume that will be mounted at the data directory.
clusterDomain: The local cluster domain for this cluster. This should be set if an alternative cluster domain is in use. If not set, then the default of cluster.local will be assumed. This field is needed to workaround https://github.com/minio/minio/issues/6775, and is expected to be removed in the future.
scope field, a
StorageScopeSpec can be specified to influence the scope or boundaries of storage that the cluster will use for its underlying storage. These properties are currently supported:
nodeCount: The number of Minio instances to create. Some of these instances may be scheduled on the same nodes, but exactly this many instances will be created and included in the cluster.
volumeClaimTemplates: A list of one or more PersistentVolumeClaim templates to use for each Minio repliace. For an example of how the list should look like, please look at the above sample.
