Integration with ROS - ApsaraDB RDS - Alibaba Cloud Documentation Center

Resource Orchestration Service (ROS) templates can be used to define cloud resources and dependencies of the resources. The ROS engine automatically creates and configures all resources based on a template to implement automated deployment and O&M. This topic describes how to use ROS to query information about an ApsaraDB RDS instance.

Supported resources

ROS is a service provided by Alibaba Cloud to simplify the management of cloud computing resources. You can create a template to describe the required cloud computing resources such as Elastic Compute Service (ECS) and ApsaraDB RDS instances, as well as the dependencies between the resources. The ROS engine automatically creates and configures all resources based on a template to implement automated deployment and O&M. For more information, see What is ROS?

You can use ROS to call ApsaraDB RDS resources. Resources that can be orchestrated by using ROS include regular resources and data resources.

Regular resources:
- ALIYUN::RDS::Account: creates an account that is used to manage a database.
- ALIYUN::RDS::AccountPrivilege: authorizes an account to access a database.
- ALIYUN::RDS::ADInfo: configures an Active Directory (AD) domain.
- ALIYUN::RDS::Connection: applies for a public endpoint for an RDS instance.
- ALIYUN::RDS::Database: creates a database on an RDS instance.
- ALIYUN::RDS::DBInstance: creates an RDS instance.
- ALIYUN::RDS::DBInstanceParameterGroup: modifies the parameters of an RDS instance.
- ALIYUN::RDS::DBInstanceSecurityIps: modifies the IP address whitelist of an RDS instance.
- ALIYUN::RDS::DBInstanceClone: restores historical data of an RDS instance to a new RDS instance. The new RDS instance is called the cloned instance.
- ALIYUN::RDS::MigrateTask: restores the data of a backup file from an Object Storage Service (OSS) bucket to an ApsaraDB RDS for SQL Server instance.
- ALIYUN::RDS::PrepayDBInstance: creates a subscription RDS instance.
- ALIYUN::RDS::ReadOnlyDBInstance: creates a read-only RDS instance.
Data resources:
- DATASOURCE::RDS::Accounts: queries account information about an RDS instance.
- DATASOURCE::RDS::DBInstance: queries information about an RDS instance.
- DATASOURCE::RDS::Databases: queries database information about an RDS instance.
- DATASOURCE::RDS::DBInstances: queries RDS instances.
- DATASOURCE::RDS::Zones: queries zones.

Configure permissions

To use ROS, you must create an Alibaba Cloud account and obtain the AccessKey pair of the account. To ensure the security of your Alibaba Cloud account and cloud resources, do not use your Alibaba Cloud account to access ApsaraDB RDS instances. We recommend that you create a Resource Access Management (RAM) user, obtain the AccessKey of the user, and grant RDS permissions to the user.

Create a RAM user.
1. Log on to the RAM console, go to the Users page, and then click Create User.
2. Set the Logon Name parameter to rds-test-operator and the Access Method parameter to Using permanent AccessKey to access.
3. Click OK.
Grant permissions to the RAM user.
1. Go to the Users page, find the RAM user that you created, and then click Add Permissions in the Actions column.
2. Attach the following policies to the RAM user:
  - AliyunRDSFullAccess: grants full permissions to query and modify RDS instances.
    Note
    You can also attach the AliyunRDSReadOnlyAccess policy that grants the permissions to query RDS instances or create a custom policy. For more information, see Create custom policies.
  - AliyunROSFullAccess: grants full permissions to manage ROS resources.
3. Click Grant permissions.

Procedure

Log on to the ROS console.
In the top navigation bar, select the region in which your RDS instance resides.
In the left-side navigation pane, click Stacks. On the page that appears, choose Create Stack > Use ROS.

Select a template and click Next.

In this example, a custom template is used to query information about an RDS instance. For more information about how to use a template, see Create a stack.

In the Specify Template section, select Select an Existing Template.
In the Template Import Method section, select Enter Template Content.

In the Template Content section, click the ROS tab and enter the template code.

The following sections show the template code in different formats. You can select a format based on your business requirements. For more information, see DATASOURCE::RDS::DBInstance.
