Authorizing a Sub-User

1. Log in to the CAM Console with the root account, select the target sub-user in the user list, and click Authorize.

2. In the pop-up dialog box, select a preset policy and click OK to complete the authorization.

• QcloudDMCFullAccess: full access to Database Management Console (DMC). It grants you permissions to use all DMC features, including adding or removing a TencentDB instance, logging in to a database, and so on.
• QcloudDMCReadOnlyAccess: read-only access to DMC. It grants you permissions to view DMC pages but not to create any tasks.

Policy Syntax

CAM policy:

{     
       "version":"2.0", 
       "statement": 
       [ 
          { 
             "effect":"effect", 
             "action":["action"], 
             "resource":["resource"], 
              "condition": {"key":{"value"}} 
          } 
      ] 
} 

• version is required. Currently, only the value "2.0" is allowed.
• statement describes the details of one or more permissions, and therefore contains the permission(s) of other elements such as effect, action, resource, and condition. One policy has only one statement.
• effect is required. It describes the result of a statement. The result can be an "allow" or an explicit "deny".
• action is required. It describes the allowed or denied operation. An operation can be an API (prefixed with "dmc:").
• resource is required. It describes the details of authorization. A resource is described in a six-segment format. Detailed resource definitions vary by product.
• condition is required. It describes the condition for the policy to take effect. Conditions consist of operators, operation keys, and operation values. A condition value may contain information such as time and IP address. Some services allow you to specify additional values in a condition.

DMC Operations

You can use DMC policy statements to authorize any API operations for any services that support DMC. To authorize DMC operations, please specify the APIs prefixed with "dmc:", such as "dmc:DescribeSlowLogTopSqls" and "dmc:DescribeSlowLogTimeSeriesStats".

To specify multiple operations in a single statement, separate them with commas as shown below:

"action":["dmc:action1","dmc:action2"]

You can also specify multiple operations using a wildcard. For example, you can specify all operations whose names begin with "Describe" as shown below:

"action":["dmc:Describe*"]

To specify all DMC operations, use the wildcard (*) as shown below:

"action":["dmc:*"]

Resources That Can Be Manipulated by DMC

Each CAM policy statement for DMC is resource-specific. DMC allows you to operate TencentDB resources added to DMC.
The format is shown below:

qcs:project_id:service_type:region:account:resource

• project_id: describes the project information and is only used to enable compatibility with legacy CAM logic. It can be left empty.
• service_type: product abbreviation, such as "dmc".
• region: region information, such as "ap-guangzhou".
• account: the root account information of the resource owner, such as "uin/65xxx763".
• resource: detailed resource information of each product, such as "instance/instance_id1" or "instance/*".

For example, you can specify an instance (dmc-k05xdcta) in the statement as shown below:

"resource":[ "qcs::dmc:ap-guangzhou:uin/65xxx763:instance/dmc-k05xdcta"]

You can also use the wildcard (*) to specify all instances that belong to a specific account as shown below:

"resource":[ "qcs::dmc:ap-guangzhou:uin/65xxx763:instance/*"]

If you want to specify all resources or if a specific API operation does not support resource-level permission control, you can use the wildcard (*) in the resource element as shown below:

"resource": ["*"]

To specify multiple resources in a single statement, separate them with commas. In the following example, we specified two resources:

"resource":["resource1","resource2"]

The table below describes the resources that can be used by TencentDB and the corresponding resource description methods, where words prefixed with "$" are placeholders, "region" refers to a region, and "account" refers to an account ID.
