Create Ceph Object Store User

We allows creation and customization of object store users through the custom resource definitions (CRDs).

TOC

Prerequisites

  • The object storage pool has been created

Procedure

Create User

Execute commands on the control node of the cluster.

cat << EOF | kubectl apply -f -
apiVersion: ceph.rook.io/v1
kind: CephObjectStoreUser
metadata:
  name: <name>
  namespace: <namespace>
spec:
  store: <ObjectStore>
  displayName: <displayName>
  clusterNamespace: <clusterNamespace>
  quotas:
    maxBuckets: 100
    maxSize: -1
    maxObjects: -1
  capabilities:
    user: "*"
    bucket: "*"
EOF

Parameters

ParametersDescription
nameThe name of the object store user to create.
namespaceThe namespace of the object store user is created.
displayNameThe display name.
clusterNamespaceThe namespace where the parent CephCluster and CephObjectStore are found. If not specified, the user must be in the same namespace as the cluster and object store. To enable this feature, the CephObjectStore allowUsersInNamespaces must include the namespace of this user.
ObjectStoreThe object store in which the user will be created. This matches the name of the object storage pool.
quotasoptional
This represents quota limitation can be set on the user.
  • maxBuckets: The maximum bucket limit for the user. Defaults to 100.
  • maxSize: Maximum size limit of all objects across all the user's buckets. Set to -1 indicates no restriction.
  • maxObjects: Maximum number of objects across all the user's buckets. Set to -1 indicates no restriction.
    • capabilitiesoptional
    Ceph allows users to be given additional permissions. 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. We supports adding read, write, read,write, or * permissions for the following resources:
  • user
  • buckets
  • usage
  • metadata
  • zone
  • roles
  • info
  • amz-cache
  • bilog
  • mdlog
  • datalog
  • user-policy
  • odic-provider
  • ratelimit

    • Allow create user in other namespaces

    If a CephObjectStoreUser is created in a namespace other than the Rook cluster namespace, the namespace must be added to this list of allowed namespaces, or specify "*" to allow all namespaces. This is useful for applications that need object store credentials to be created in their own namespace.

    Execute commands on the control node of the cluster.

    kubectl -n rook-ceph patch cephobjectstore <ObjectStore> --type merge -p '{"spec":{"allowUsersInNamespaces":["*"]}}'

    Get user information

    Execute commands on the control node of the cluster.

    user_secret=$(kubectl -n <namespace> get cephobjectstoreuser <user-name> -o jsonpath='{.status.info.secretName}')

# ACCESS_KEY
kubectl -n <namespace> get secret $user_secret -o jsonpath='{.data.AccessKey}' | base64 --decode

# SECRET_KEY
kubectl -n <namespace> get secret $user_secret -o jsonpath='{.data.SecretKey}' | base64 --decode
