This script exploits the error document functionality of S3 static websites to create an Apache-style directory index of your bucket.

1. Copy list.html into the S3 bucket where you want to serve a directory listing.

   • Edit s3Params to reflect the bucket name and appropriate S3 endpoint. (reference)
   • Edit ignoreList to exclude any files from the directory index.

2. Grant Everyone List permissions.

3. Enable Static Website Hosting.

   • Set the Index Document to index.html.
   • Set the Error Document to list.html.
   • Note the endpoint.

4. Add the following CORS policy:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedOrigin>http://{{ endpoint }}</AllowedOrigin>
    </CORSRule>
</CORSConfiguration>
