Cloudfront: setting s3 path difference from Origin

Cache behaviour setting, i use

s3/*

to redirect request to s3 folder, but i don't want to place my images under a folder named s3 but right under s3 bucket to redirect like this:

xxxx.cloudfront.com/s3/images/1.png  -> bucket_name/images/1.png

not 

xxxx.cloudfront.com/s3/images/1.png  -> bucket_name/s3/images/1.png

Please help to show me how to config like this.

You can do this with lambdas here's the relevant lambda snippet.

exports.handler = (event, context, callback) => {
    // this is the request we want to re-map
    var request = event.Records[0].cf.request;

    // the request has a 'uri' property which is the value we want to overwrite
    // rewrite the url applying your custom logic
    request.uri = 'some custom logic here to rewrite the url';    

    // quit the lambda and let the request chain continue
    callback( null, request );    
};

I don't think this is possible. An Origin Path can redirect to a subdirectory, (eg index.htm -> production/index.htm) but CloudFront can't strip out path portions.

See documentation: Origin Path

Some options:

  • Use a separate distribution instead of prefixing paths with s3
  • Just put s3/ at the front of your filenames (and actually use the full path)

Unfortunately this is not possible. Cloudfront will map the exact request path back to the origin. The only option it provides for manipulating the origin path is to add a prefix - it does not permit removing anything from the path.

Origin Path has details on the Origin path setting - but you'll see from that page there is no option to remove any part of the Request Path.
