This topic describes how to use Outputs in a template to display descriptions in Chinese and sort parameters in a specific order in Resource Orchestration Service (ROS).

Sample templates

  • ROS template

    Outputs:
  TiDB:
    Label: TiDB
    Value:
      Fn::Sub:
        - mysql://${ServerAddress}:4000
        - ServerAddress:
            Fn::GetAtt:
              - SlbTiDB
              - IpAddress
  TiDB Dashboard:
    Label:
      en: Specifications-EN
      zh-cn: Specifications-cn
    Value:
      Fn::Sub:
        - http://${ServerAddress}:2379
        - ServerAddress:
            Fn::GetAtt:
              - ControlServerEip
              - EipAddress
  Grafana:
    Label:
      en: Grafana-EN
      zh-cn: Grafana-cn
    Value:
      Fn::Sub:
        - http://${ServerAddress}:3000
        - ServerAddress:
            Fn::GetAtt:
              - ControlServerEip
              - EipAddress
    ErrorData:
      Description: JSON serialized dict containing data associated with wait condition error signals sent to the handle.
      Value:
        Fn::GetAtt:
          - InvocationWaitCondition
          - ErrorData
Metadata:
  ALIYUN::ROS::Interface:
    Outputs:
      - TiDB
      - TiDB Dashboard
      - Grafana
      - ErrorData
    Parameters:
    • Outputs: defines the order in which parameters are sorted. You can specify Outputs in the Metadata section to define the order.
    • Label: defines parameters in English and Chinese.

  • Terraform template

    output "graph_private_ip" {
  description = <<EOT
  {
    "Label": "The private ip",
    "Description": "The private ip of the graph nodes."
  }
  EOT
  value       = join("\n", module.graph-nodes.this_private_ip)
}

Sample GUI

After the stack is created, you can view the descriptions in Chinese and the order in which the parameters are sorted on the Stack Information tab.
