:List of API operations by function

Stack operations

You can define a template for resources in a stack and their dependencies and use the template to create stacks. After the stacks are created, you can query, update, or delete the stacks.

Resource operations

ROS allows you to manage a variety of resources. You can query resource templates by resource type or query details of resource types or resources in a specified stack to obtain the information of resources in ROS.

For more information about the resource types supported by ROS, see List of resource types by service.

Scenario operations

ROS provides the scenario feature to facilitate resource management. You can add resources to a scenario in the console and perform operations such as replication and centralized management on the resources.

Template operations

A template is a JSON or YAML text file that defines resources in a stack and their dependencies and can be used to create stacks. For example, you can call the CreateTemplate operation to create a template that contains the ALIYUN::ECS::VPC resource, and then call the CreateStack operation to create a stack. This way, you can create a virtual private cloud (VPC).

In addition, you can query the template ID, template content, or resource prices defined in the template. You can also share your template with other users. This way, one template can be used by multiple Alibaba Cloud accounts to allow stacks to be efficiently created.

Stack policy operations

A stack policy is a JSON or YAML text file that is used to define the update operations for a specified stack to prevent resources in the stack from being accidentally updated or deleted during the update of the stack. You can configure or query stack policies.

Change set operations

You can create and execute change sets to update running stacks.

Stack group operations

You can use a stack group as a unit to manage stacks in ROS. You can use templates to create stack groups. This way, you can create stacks within multiple Alibaba Cloud accounts across regions. You can also query the information of stack groups and stack group operations.

After you call the CreateStackGroup operation to create a stack group, you can call the CreateStackInstances operation to create a stack instance within a specified account in a specified region.

Drift detection operations

When you change resource configurations by using a service that is beyond the control of ROS, the related stack or stack group may experience drift. You can perform drift detection to correct drift. For example, you can call the DetectStackDrift operation to perform drift detection on a stack. If the stack has drifted, you can call the UpdateStackTemplateByResources operation to modify the stack template to eliminate stack drift.

Tag operations

You can add tags to stacks, stack groups, or templates for classification and management purposes.

Other operations

When you create a stack, stack group, or stack instance, you must specify the RegionId parameter. In this case, you can call the DescribeRegions operation to query the most recent region list.

When you create or update a stack, you can call the SignalResource operation to send signals. Failure signals can cause stack creation or update to fail.

In addition, you can call the GetServiceProvisions operation to query the activation status and the RAM role information of multiple cloud services at the same time, and call the GetFeatureDetails operation to query the details of specific features supported by ROS.
