Creating a Bucket Policy with a Template

OBS Console provides bucket policy templates for multiple typical scenarios. You can use these templates to quickly configure bucket policies.

Ways to Configure Bucket Policies

You can use OBS Console, APIs, SDKs, OBS Browser+, or obsutil to configure bucket policies.

Using OBS Console

In the navigation pane of OBS Console, choose Object Storage.
In the bucket list, click the bucket you want to operate. The Objects page is displayed.
In the navigation pane, choose Permissions > Bucket Policies.
Click Create.

Choose a policy template. For details about the parameters, see Bucket Policies.
