When you create a stack in the Resource Orchestration Service (ROS) console to manage multiple categories of resources, you may need to open multiple consoles to query resource parameters. In the Parameters section of a template, you can specify AssociationProperty for parameters to query the resources in the specified region and specify AssociationPropertyMetadata to add filter conditions for the parameters. This way, you can select parameter configurations based on optional values in the ROS console.
Parameters
You can specify one of the following types of values for parameters in AssociationPropertyMetadata:
A literal value. For example, if you set AssociationPropertyMetadata to
"RegionId": "cn-hangzhou"
, ROS resolves this value as the literal value cn-hangzhou.A variable. Specify a variable in the
${ParameterKey}
format. For example, if you set AssociationPropertyMetadata to"VpcId": "${VpcId}"
, ROS resolves this value as a variable that varies based on the value of the VpcId parameter in the template.NoteIf you want to specify a variable in the
${ParameterKey}
format as a literal value, you can add an exclamation point (!) to ${ParameterKey} to use the ${!ParameterKey} format. For example, if you set a value to${!Literal}
, ROS resolves this value as${Literal}
.If you want to specify a variable for a parameter in a Terraform template, add a dollar sign (
$
) to${ParameterKey}
to use the $${ParameterKey} format. For example, if you set AssociationPropertyMetadata to"VpcId": "$${VpcId}"
, ROS resolves this value as a variable that varies based on the value of the VpcId parameter in the Terraform template.
The supported parameters in AssociationPropertyMetadata vary based on different categories of resources that you specify as AssociationProperty values. The following section describes the mappings between the AssociationProperty values and the parameters in AssociationPropertyMetadata in ROS.
Basic resource
Value of AssociationProperty | Description | Parameter in AssociationPropertyMetadata |
Auto | ROS automatically generates parameters, such as AssociationProperty and AssociationPropertyMetadata, based on the original data structure of Terraform. Note This value takes effect only for the JSON parameters in Terraform templates. | Overwrite: optional. Appends values to or overwrites the declarations of nested parameters in the inner level. The value of Overwrite is of the dictionary data type and consists of key-value pairs. |

TimeTriggerWeekly | The time picker that allows you to specify the interval by weekday. | Example: |
TimeZone | The time zone. | Example: |
Null | The ROS console displays the settings of a parameter only after you click the relevant button. This value takes effect only for JSON parameters.

The following section describes the parameters:
UserName: the username. The value of UserName is of the string data type and must be 6 to 12 characters in length. Valid values:
anonymous (default)
user-one
user-two
PassWord: the password. The value of PassWord is of the string data type. No default value is provided. The value must be 1 to 41 characters in length, and can contain letters and digits.
NoEcho is set to true. A value of true specifies that ROS returns a password masked as asterisks (*) after you query the stack.
ImageId: the image ID. The value of ImageId is of the string data type.
AssociationProperty is set to ALIYUN::ECS::Image::ImageId. This way, the ROS console checks whether the ID of the specified image is available when you create the stack. The ROS console also displays the IDs of other images that are available in the same region as the specified image in a drop-down list.
Example 2: AssociationPropertyMetadata
In this example, AssociationProperty and AssociationPropertyMetadata are specified to query the vSwitch in the specified VPC and zone. For AssociationPropertyMetadata, RegionId is set to the literal value cn-hangzhou, VpcId is set to the variable ${VpcId}, and ZoneId is set to the variable ${EcsZone}. ${VpcId} varies based on the value of ALIYUN::ECS::VPC::VPCId, and ${EcsZone} varies based on the value of ZoneId. This way, the vSwitch is associated with the specified VPC and zone.
The AllowedValues parameter is specified for EcsZone. AutoChangeType is set to false in AssociationPropertyMetadata. This way, the ROS console displays the values of the AllowedValues parameter as a drop-down list.
