Granting IAM User Groups Specific Permissions for All OBS Resources

Scenario

This topic describes how to grant multiple IAM users or user groups specified permissions for all OBS resources.

Recommended Configuration

Use an IAM custom policy to configure the permissions.

Precautions

After configuration, IAM user groups can perform allowed operations using APIs or SDKs. If they log in to OBS Console or OBS Browser+ to perform those operations, a message will be displayed indicating that they do not have required permissions.

This is because when they log in to OBS Console or OBS Browser+, APIs (such as ListAllMyBuckets and ListBucket) are called to load the bucket list and object list and some other APIs will also be called on other pages, but their permissions do not cover those APIs. In such case, the message is displayed.

To allow IAM users to operate buckets and objects on OBS Console or OBS Browser+, add at least the obs:bucket:ListAllMyBuckets and obs:bucket:ListBucket permissions to the custom policy.

Procedure

  1. Log in to Huawei Cloud and click Console in the upper right corner.
  2. On the console, hover over the username in the upper right corner, and choose Identity and Access Management from the drop-down list.
  3. In the navigation pane, choose Permissions > Policies/Roles > Create Custom Policy.
  4. Configure a custom policy.

    Parameter

    Description

    Policy Name

    Enter a policy name.

    Policy View

    Select one based on your own habits. Visual editor is used here.

    Policy Content

    Scope

    The default value is Global services.

  5. Click OK.
  6. Create a user group and assign permissions.

    Apply the created custom policy to the user group by following the instructions in the IAM document.

  7. Add the IAM user you want to authorize to the created user group.

    Due to data caching, it takes about 10 to 15 minutes for a custom policy to take effect.
