How to make an AWS S3 bucket accessible over HTTP?

Question

Does AWS S3 provide a way to make bucket's files available over HTTP preferably protected with BASIC_AUTH? I mean listing the files (index) and make it possible to download them over HTTP.

Answer 1

1. Download - yes. Simply set each Object ACL to be publicly readable.

2. List - sort of. If you set the Bucket ACL to publicly readable anyone can list the content. However it's a rather human-unfriendly XML listing.

   You can generate your directory listings to some index.html files through an external process and configure the bucket to serve those.

3. Basic auth - nope. You can look at something like S3 pre-signed URLs to protect the content.

Hope that helps :)

Answer 2

One possibility is mounting the bucket as s3fs and serving the root folder as usually done by Nginx.

Answer 3

In addition to Mlu answer, you can put Cloud front in front of the bucket and implement basic auth and probably listing/sorting with a Lambda@edge function.
