GaussDB

Updated on 2025-02-25 GMT+08:00

The Organizations service provides Service Control Policies (SCPs) to set access control policies.

SCPs do not actually grant any permissions to a principal. They only set the permissions boundary for the principal. When SCPs are attached to a member account or an organizational unit (OU), they do not directly grant permissions to that member account or OU. Instead, the SCPs just determine what permissions are available for that member account or the member accounts under that OU.

This section describes the elements used by Organizations SCPs. The elements include actions, resources, and conditions.

For details about how to use these elements to create a custom SCP, see Creating an SCP.

Actions

Actions are specific operations that are allowed or denied in an SCP.

  • The Access Level column describes how the action is classified (List, Read, or Write). This classification helps you understand the level of access that an action grants when you use it in an SCP.
  • The Resource Type column indicates whether the action supports resource-level permissions.
    • You can use a wildcard (*) to indicate all resource types. If this column is empty (-), the action does not support resource-level permissions, and you must specify all resources ("*") in your SCP statements.
    • If this column includes a resource type, you must specify the URN in the Resource element of your statements.
    • Required resources are marked with asterisks (*) in the table. If you specify a resource in a statement using this action, then it must be of this type.

    For details about the resource types defined by GaussDB, see Resources.

  • The Condition Key column contains keys that you can specify in the Condition element of an SCP statement.
    • If the Resource Type column has values for an action, the condition key takes effect only for the listed resource types.
    • If the Resource Type column is empty (-) for an action, the condition key takes effect for all resources that action supports.
    • If the Condition Key column is empty (-) for an action, the action does not support any condition keys.

    For details about the condition keys defined by GaussDB, see Conditions.

The following table lists the actions that you can define in SCP statements for GaussDB.

Resources

A resource type indicates the resources that an SCP applies to. If you specify a resource type for any action in Table 12, the resource URN must be specified in the SCP statements using that action, and the SCP applies only to resources of this type. If no resource type is specified, the Resource element is marked with an asterisk (*) and the SCP applies to all resources. You can also set condition keys in an SCP to define resource types.

The following table lists the resource types that you can define in SCP statements for GaussDB.

Table 12 Resource types supported by GaussDB

Resource Type

URN

instance

gaussdb:<region>:<account-id>:instance:<instance-id>

Conditions

A Condition element lets you specify conditions for when an SCP is in effect. It contains condition keys and operators.

  • The condition key that you specify can be a global condition key or a service-specific condition key.
    • Global condition keys (with the g: prefix) apply to all actions. Cloud services do not need to provide user identity information. Instead, the system automatically obtains such information and authenticates users. For details, see Global Condition Keys.
    • Service-specific condition keys (with the abbreviation of a service name plus a colon as the prefix, for example, gaussdb:) apply only to operations of the GaussDB service. For details, see Table 13.
    • The number of values associated with a condition key in the request context of an API call makes the condition key single-valued or multivalued. Single-valued condition keys have at most one value in the request context of an API call. Multivalued condition keys can have multiple values in the request context of an API call. For example, a request can originate from at most one VPC endpoint, so g:SourceVpce is a single-valued condition key. You can tag resources and include multiple tag key-value pairs in a request, so g:TagKeys is a multivalued condition key.
  • A condition operator, condition key, and a condition value together constitute a complete condition statement. An SCP can be applied only when its request conditions are met. For supported condition operators, see Condition operators.

The following table lists the condition keys that you can define in SCPs for GaussDB. You can include these condition keys to specify conditions for when your SCP is in effect.

Table 13 Service-specific condition keys supported by GaussDB

Service-specific Condition Key
