Object Store User CRD

Rook allows creation and customization of object store users through the custom resource definitions (CRDs). The following settings are available for Ceph object store users.


kind: CephObjectStoreUser
  name: my-user
  namespace: rook-ceph
  store: my-store
  displayName: my-display-name
    maxBuckets: 100
    maxSize: 10G
    maxObjects: 10000
    user: "*"
    bucket: "*"

Object Store User Settings


  • name: The name of the object store user to create, which will be reflected in the secret and other resource names.
  • namespace: The namespace of the Rook cluster where the object store user is created.


  • store: The object store in which the user will be created. This matches the name of the objectstore CRD.
  • displayName: The display name which will be passed to the radosgw-admin user create command.
  • quotas: This represents quota limitation can be set on the user (support added in Rook v1.7.3 and up). Please refer here for details.
  • maxBuckets: The maximum bucket limit for the user.
  • maxSize: Maximum size limit of all objects across all the user's buckets.
  • maxObjects: Maximum number of objects across all the user's buckets.
  • capabilities: Ceph allows users to be given additional permissions (support added in Rook v1.7.3 and up). Due to missing APIs in go-ceph for updating the user capabilities, this setting can currently only be used during the creation of the object store user. If a user's capabilities need modified, the user must be deleted and re-created. See the Ceph docs for more info. Rook supports adding read, write, read, write, or * permissions for the following resources:
  • users
  • buckets
  • usage
  • metadata
  • zone
