What do you need to set when you configure a bucket as a public static website?

A
  • disable block public access settings for the bucket
  • write a bucket policy that grants public read access.
  • If your bucket contains objects that are not owned by the bucket owner, you might also need to add an object access control list (ACL) that grants everyone read access.
