Blueprint Example

Example 1:

tosca_definitions_version: cloud_tosca_version_1_0
inputs:
  storage-name:
    default: my-evc-storage
node_templates:
  my-storage:
    type: Cloud.CCE.Storage.OBS
    properties:
      name: {get_input: storage-name}

Example 2: Custom K8s Manifest for Orchestration

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

    type: Cloud.CCE.Storage.OBS
    properties:
      apiVersion: v1
      kind: PersistentVolumeClaim
