**Table 1** Property Description
Property	Required	Descripiton
k8sManifest	No	K8s-native manifest object of the OBS, based on which you can create OBS resources to replace other configuration items Type: dict Value Constraint: The value must meet the Kubernetes specifications. Suggestion: For details, see the sample or CCE documentation.
name	No	PVC name Type: string Value Description: Supports customization. Value Constraint: Each PVC name must be unique in a namespace. The value must contain 1 to 24 characters and meet the following requirement: (^$) \| (^[a-z] ([-a-z0-9][a-z0-9])?$). Suggestion:* Customize the value.
clusterId	No	ID of the cluster to which the resource belongs Type: HuaweiCloud.CCE.Cluster.Id Value Description: Indicates the ID of an existing or new container cluster. Value Constraint: The value must satisfy the UUID rule and support a maximum of 64 characters. Suggestion: Enter the cluster ID. Specifically, log in to the CCE console, and choose Resource Management > Clusters. Click the target cluster, and you can then obtain its cluster ID. Connect to the cluster object and use the get_reference function to obtain the cluster ID. Leave it blank, and specify the ID on the AOS console when creating a stack.
namespace	No	Namespace of the cluster to which the resource belongs Type: string Value Description: Must be a valid namespace in the cluster, for example, default. Value Constraint: The value must start with a letter. Only lowercase letters, digits, and hyphens (-) are allowed.

Blueprint Example

Example 1:

tosca_definitions_version: huaweicloud_tosca_version_1_0
inputs:
  storage-name:
    default: my-evc-storage
node_templates:
  my-storage:
    type: HuaweiCloud.CCE.Storage.OBS
    properties:
      name: {get_input: storage-name}

Example 2: Custom K8s Manifest for Orchestration

For clusters of version 1.15, the example configuration of the YAML file is as follows:

tosca_definitions_version: huaweicloud_tosca_version_1_0
node_templates:
  my-storage:
    type: HuaweiCloud.CCE.Storage.OBS
    properties:
      apiVersion: v1
      kind: PersistentVolumeClaim
      metadata:
        annotations:
          everest.io/obs-volume-type: STANDARD
        name: cce-obs-k7yhr36u-iuu9
        namespace: default
      spec:
        accessModes:
        - ReadWriteMany
        resources:
          requests:
            storage: 1Gi
        storageClassName: csi-obs

For clusters of version 1.13 or earlier, the example configuration of the YAML file is as follows:

tosca_definitions_version: huaweicloud_tosca_version_1_0
node_templates:
  my-storage:
    type: HuaweiCloud.CCE.Storage.OBS
    properties:
      apiVersion: v1
      kind: PersistentVolumeClaim
      metadata:
        annotations:
          volume.beta.kubernetes.io/storage-class: obs-standard
          volume.beta.kubernetes.io/storage-provisioner: flexvolume-huawei.com/fuxiobs
        name: cce-obs-k7yhr36u-iuu9
        namespace: default
      spec:
        accessModes:
        - ReadWriteMany
        resources:
          requests:
            storage: 10Gi
