Policy Structure

An RBAC policy consists of a Version, a Statement, and Depends.

Policy Syntax

When selecting a policy for a user group, click below the policy to view the details of the policy. The DWS Administrator policy is used as an example to describe the syntax of RBAC policies.

{
        "Version": "1.0",
        "Statement": [
                {
                        "Effect": "Allow",
                        "Action": [
                                "dws:dws:*"
                        ]
                }
        ],
        "Depends": [
                {
                        "catalog": "BASE",
                        "display_name": "Server Administrator"
                },
                {
                        "catalog": "BASE",
                        "display_name": "Tenant Guest"
                }
        ]
}

Parameter		Meaning	Value
Version		Policy version	The value is fixed to 1.0.
Statement	Action	Operations to be performed on GaussDB(DWS)	Format: Service name:Resource type:Operation. dws:dws:*: Permissions for performing all operations on all resource types in GaussDB(DWS).
	Effect	Whether the operation defined in an action is allowed	Allow Deny
Depends	catalog	Name of the service to which dependencies of a policy belong	Service name Example: BASE
	display_name	Name of a dependent policy	Policy name Example: Server Administrator

Note

When using RBAC for authentication, pay attention to the Depends parameter and grant other dependent permissions at the same time.

For example, the DWS Administrator permission depends on the Server Administrator and Tenant Guest permissions. When granting the DWS Administrator permission to users, you also need to grant the two dependent permissions to the users.
