Resource Orchestration Service:Automatically activate Alibaba Cloud services

Supported services

The ServiceName parameter in ALIYUN::ROS::AutoEnableService accepts a specific set of values. Each value maps to a cloud service. For the full list, see ALIYUN::ROS::AutoEnableService.

Activate a single service

This example activates Simple Log Service (SLS). To activate a different service, change the Default value under ServiceName to the target service code, such as OSS for Object Storage Service.

1. Log on to the ROS console.

2. In the navigation pane on the left, click Stacks.

3. In the top menu bar, select a region for the stack from the region drop-down list. For example, select China (Hangzhou).

4. On the Stacks page, click Create Stack. In the Specify Template section, click Select an Existing Template.

   Note

   • If you select Create a New Template or ROS Infrastructure Composer, you are redirected to the corresponding page.

5. In the Select Template step, select Select an Existing Template in the Specify Template section. Set Template Import Method to Enter Template Content, paste the following YAML template into the Template Content code editor, and then click Next.

   ROSTemplateFormatVersion: '2015-09-01'
   Parameters:
     ServiceName:
       Type: String
       Default: SLS
   Resources:
     AutoEnableService:
       Type: ALIYUN::ROS::AutoEnableService
       Properties:
         ServiceName:
           Ref: ServiceName
   

6. In the Configure Parameters step, specify Stack Name.

7. Click Create.

After the stack is created, log on to the Simple Log Service console and confirm that the service is available.

Activate multiple services

This example activates Simple Log Service and Object Storage Service (OSS). The ServiceName parameter holds a JSON array of service codes. The template iterates over them using built-in functions.

1. Log on to the ROS console.

2. In the navigation pane on the left, click Stacks.

3. In the top menu bar, select a region for the stack from the region drop-down list. For example, select China (Hangzhou).

4. On the Stacks page, click Create Stack. In the Specify Template section, click Select an Existing Template.

   Note

   • If you select Create a New Template or ROS Infrastructure Composer, you are redirected to the corresponding page.

5. In the Select Template step, select Select an Existing Template in the Specify Template section, set Template Import Method to Enter Template Content, paste the following YAML template into the Template Content code editor, and then click Next.

   The following table describes the template functions used in this example.

   Function	Purpose
   Fn::Length	Returns the number of items in the ServiceName array. Count uses this value to create one AutoEnableService resource per service.
   ALIYUN::Index	A pseudo parameter that resolves to the current iteration index (0, 1, 2, ...).
   Fn::Select	Picks the service code at the current index from the ServiceName array.

   For details on all template functions, see Functions.
