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.SFS
    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:

tosca_definitions_version: cloud_tosca_version_1_0
node_templates:
  my-storage:
    type: Cloud.CCE.Storage.SFS
    properties:
      apiVersion: v1
      kind: PersistentVolumeClaim
      metadata:
        annotations:
          volume.beta.kubernetes.io/storage-class: nfs-rw
          volume.beta.kubernetes.io/storage-provisioner: flexvolume.com/fs
        name: cce-sfs-k7yimkqa-p66e
