CloudOps Orchestration Service:Template parameters

Parameters:
  parameter-name-1: # The name of the parameter. The name can contain letters, digits, backslashes (\), underscores (_), and hyphens (-). Spaces are not allowed. We recommend that you use the lower camel case for a parameter name. Example: instanceId. 
    Type: String # Optional. The type of the parameter. Valid values: List, Number, String, Boolean, and Json. Default value: String.
    Description: description # Optional. The description of the parameter, such as the usage of the parameter.
    AssociationProperty: DateTime # Optional. The property of a parameter. This facilitates parameter setting when you use the template to create an execution. After you specify a property for a parameter, you can specify the parameter in the CloudOps Orchestration Service (OOS) console more easily than entering the value in a text box. For example, you can select a value from a drop-down list, specify time on a tab, or enter commands in a code editor. If you want a parameter to specify the type of Elastic Compute Service (ECS) instances, you can specify ALIYUN::ECS::Instance::InstanceType for the AssociationProperty parameter. Then, when you specify the parameter-name-1 parameter, a drop-down list with all available instance types is provided for you to select. If you want the parameter to specify shell commands, you can specify the Code property for the AssociationProperty parameter. Then, a code editor is provided for you to enter commands. This is more user-friendly than entering commands in a small input box. The following properties are available: ALIYUN::ECS::Instance::InstanceType, ALIYUN::ECS::SecurityGroup::SecurityGroupId, ALIYUN::VPC::VSwitch::VSwitchId, ALIYUN::ECS::Image::ImageId, Targets, RateControl, Code, DateTime, Cron, and TimeZone. You can also use the AssociationPropertyMetadata parameter to define a parameter property in a fine-grained manner. For example, if you specify the DateTime property for the AssociationProperty parameter, you can set the time format of the parameter value by using the AssociationPropertyMetadata parameter. 
    AssociationPropertyMetadata:
      Format: 'YYYY-MM-DDThh:mm:ssZ'   # The fine-grained definition of the property that you specify by using the AssociationProperty parameter. The AssociationPropertyMetadata parameter determines how the value of the parameter-name-1 parameter is displayed. For example, if you set the Format parameter to YYYY-MM-DDThh:mm:ssZ, you can specify the date and time on a tab. If you set the Format parameter to hh:mm:ssZ, you can specify only the time on a tab. 
    Default: default-value # Optional. The default value of the parameter.
    AllowedValues: # Optional. Valid values of the parameter. 
      - value1
      - value2
    AllowedPattern: regular-expression # Optional. The regular expression that the parameter value must match. This attribute is valid only if the parameter value is of the String type.
    MinLength: 1 # Optional. The minimum length of the parameter value. This parameter is valid only if the parameter value is of the String type.
    MaxLength: 10 # Optional. The maximum length of the parameter value. This parameter is valid only if the parameter value is of the String type.
