IAM

Updated on 2024-01-09 GMT+08:00

This section describes the IAM permission configurations for all ModelArts functions.

IAM Permissions

If you need to assign different permissions to employees in your enterprise to access your ModelArts resources, Identity and Access Management (IAM) is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you securely access Huawei Cloudcloud resources. If your Huawei accountaccount can meet your requirements and you do not need an IAM account to manage user permissions, skip this chapter.

IAM is a free service. You only pay for the resources in your account.

With IAM, you can control access to specific Huawei Cloudcloud resources. For example, if the software developers in your enterprise need to own permissions to use ModelArts, yet you do not want them to own high-risk operation permissions such as deleting ModelArts, you can grant permissions using IAM to limit their permission on ModelArts.

For details about IAM, see What is IAM?What is IAM?.

Role/Policy-based Authorization

ModelArts supports role/policy-based authorization. By default, new IAM users do not have any permissions. You need to add a user to one or more groups, and assign permissions policies or roles to these groups. Users inherit permissions of the groups to which they are added. This process is called authorization. The users then inherit permissions from the groups and can perform specified operations on cloud services.

ModelArts is a project-level service deployed for specific regions. When you set Scope to Region-specific projects and select the specified projects (for example, ap-southeast-2) in the specified regions (for example, AP-Bangkok), the users only have permissions for APIG resources in the selected projects. If you set Scope to All resources, the users have permissions for APIG resources in all region-specific projects. When accessing ModelArts, the users need to switch to a region where they have been authorized to use cloud services.

Table 1 lists all system-defined policies supported by ModelArts. If preset ModelArts permissions cannot meet your requirements, create a custom policy by referring to Policy Fields in JSON Format.

If system-defined policies cannot meet your requirements, you can create a custom policy. For details about the actions supported by custom policies, see ModelArts Resource Permissions.

You can create custom policies in either of the following ways:

  • Visual editor: Select cloud services, actions, resources, and request conditions without the need to know policy syntax.
  • JSON: Create a JSON policy or edit an existing one.

For details, see Creating a Custom Policy. The following lists examples of common ModelArts custom policies.

  • Example 1: Grant permission to manage images.
    {
        "Version": "1.1",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "modelarts:image:register",
                    "modelarts:image:listGroup"
                ]
            }
        ]
    }
  • Example 2: Grant permission to deny creating, updating, and deleting a dedicated resource pool.

    A policy with only "Deny" permissions must be used together with other policies. If the permissions granted to an IAM user contain both "Allow" and "Deny", the "Deny" permissions take precedence over the "Allow" permissions.

    {
        "Version": "1.1",
        "Statement": [
            {
                "Action": [
                    "modelarts:*:*"
                ],
                "Effect": "Allow"
            },
            {
                "Action": [
                    "swr:*:*"
                ],
                "Effect": "Allow"
            },
            {
                "Action": [
                    "smn:*:*"
                ],
                "Effect": "Allow"
            },
            {
                "Action": [
                    "modelarts:pool:create",
                    "modelarts:pool:update",
                    "modelarts:pool:delete"
                ],
                "Effect": "Deny"
            }
        ]
    }
  • Example 3: Create a custom policy containing multiple actions.

    A custom policy can contain actions of multiple services that are of the global or project-level type. The following is an example policy containing actions of multiple services:

    {
        "Version": "1.1",
        "Statement": [
            {
                "Effect": "Allow",
                "Action": [
                    "modelarts:service:*"
                ]
            },
            {
                "Effect": "Allow",
                "Action": [
                    "lts:logs:list"
                ]
            }
        ]
    }

Policy Fields in JSON Format

Policy Structure

A policy consists of a version and one or more statements (indicating different actions).

Figure 1 Policy structure

Policy Parameters

The following describes policy parameters. You can create custom policies by specifying the parameters. For details, see Custom Policy Use Cases.

Table 3 Policy parameters

Parameter

Description

Value

Version

Policy version

1.1: indicates policy-based access control.

Statement: authorization statement of a policy

Effect

Whether to allow or deny the operations defined in the action

  • Allow: indicates the operation is allowed.
  • Deny: indicates the operation is not allowed.
    NOTE:

    If the policy used to grant user permissions contains both Allow and Deny for the same action, Deny takes precedence.

Action

Operation to be performed on the service

Format: "Service name:Resource type:Action". Wildcard characters (*) are supported, indicating all options.

Example:

modelarts:notebook:list: indicates the permission to view a notebook instance list. modelarts indicates the service name, notebook indicates the resource type, and list indicates the operation.

View all actions of a service in its API Reference.

Condition

Condition for a policy to take effect, including condition keys and operators

Format: "Condition operator:{Condition key:[Value 1,Value 2]}"

If you set multiple conditions, the policy takes effect only when all the conditions are met.

Example:

StringEndWithIfExists":{"g:UserName":["specialCharacter"]}: The statement is valid for users whose names end with specialCharacter.

Resource

Resources on which a policy takes effect

Format: Service name:<Region>:<Account ID>:Resource type:Resource path. Asterisks (*) are supported for resource type, indicating all resources.

NOTE:

ModelArts authorization does not allow you to specify a resource path.

ModelArts Resource Types

Administrators can specify the scope based on ModelArts resource types. The following table lists the resource types supported by ModelArts:
