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