Resource Orchestration Service:Use elements in ROS templates to configure JSON data

Resource Orchestration Service (ROS) allows you to use the elements of one-dimensional arrays, multidimensional arrays, and jsonSchema in templates to extend JSON data and enhance the verification logic of JSON data.

One-dimensional array

A one-dimensional array is a collection of elements of the same type. The elements in a one-dimensional array support all types of ROS template parameters.

Sample template

ROSTemplateFormatVersion: '2015-09-01'
Parameters:
  listParameter:
    Type: Json
    AssociationProperty: List[Parameter]
    AssociationPropertyMetadata:
      Parameter:
        Type: String
    Default:
      - a
      - b
      - c         

Sample GUI

When you use the sample template to create a stack or stack group in the ROS console, the elements in the one-dimensional array are rendered as parameters and values.

Multidimensional array

A multidimensional array is a collection of elements of different types. The elements in a multidimensional array support all types of ROS template parameters.

Sample template

ROSTemplateFormatVersion: '2015-09-01'
Parameters:
  listParameters:
    Type: Json
    AssociationProperty: List[Parameters]
    AssociationPropertyMetadata:
      Parameters:
        p1:
          Type: String
        p2:
          Type: Boolean
      ListMetadata:
        ShowHeader: true
        ShowRemove: true
        ShowAddition: true
        Order:
          - p2
          - p1
    Default:
      - p1: p10
        p2: true
      - p1: p11
        p2: false

Sample GUI

When you use the sample template to create a stack or stack group in the ROS console, the elements in the multidimensional array are rendered as parameters and values.

jsonSchema

jsonSchema is used to define and render the schema of elements. The elements in jsonSchema support all types of ROS template parameters.

Sample template

ROSTemplateFormatVersion: '2015-09-01'
Parameters:
  jsonSchema:
    Type: Json
    AssociationPropertyMetadata:
      Parameters:
        a:
          Type: String
          Description: a from Json
          Default: '123'
        b:
          Type: Boolean
          Description: b from Json
          Default: true
        c:
          Type: String
          Description: c from Json
          AssociationProperty: ALIYUN::ECS::VSwitch::VSwitchId
        d:
          Type: String
          Description: d from Json
          Default: d

Sample GUI

When you use the sample template to create a stack or stack group in the ROS console, the elements in jsonSchema are rendered as parameters and values.
