Public access to the bucket.

Object Storage incorporates several access management mechanisms. To learn how these mechanisms interact, see Access management methods in Object Storage: Overview.

By default, bucket access is restricted, as specified in the IAM settings. You can enable public access:

  • To read objects in a bucket.
  • To view the list of objects in a bucket.
  • To read settings:
    • CORS
    • Static website hosting
    • Object lifecycles

Public access to each operation is granted separately. This means, if you have granted only read access to your objects, anonymous users cannot get the list of objects and bucket settings.

Warning

Public access is granted to an unlimited number of anonymous users. Use it only when other access grant mechanisms are not available.

If required, you can configure permissions to the buckets and objects they contain using ACLs or the access policy.
