Set bucket policies

The ECS Portal provides a Bucket Policy Editor to enable you to create a bucket policy for an existing bucket.

For each bucket, you can define ACLs for an object user. Bucket policies provide greater flexibility than ACLs and allow fine grained control over permissions for bucket operations and for operations on objects within the bucket. Policy conditions are used to assign permissions for a range of objects that match the condition and are used to automatically assign permissions to newly uploaded objects.

Policy conditions are used to assign permissions for a range of objects that match the condition and are used to automatically assign permissions to newly uploaded objects. The typical scenarios in which you would use bucket policies are described here.

Policies are defined in JSON format and the syntax used for policies is the same as that used for Amazon AWS. The operations for which permissions can be assigned are limited to those operations supported by ECS. For more information, see the ECS Data Access Guide, available from https://www.dell.com/support/.

The bucket policy editor has a code view and a tree view. The code view, shown in the following screenshot, enables you to enter JSON policies from scratch or to paste existing policies into the editor and modified. For example, if you have existing policies in JSON format, you can paste them into the code view and modify them.

The tree view, shown in the following screenshot, provides a mechanism for navigating a policy and is useful where you have a large number of statements in a policy. You can expand and contract the statements and search them.
