Connection to an S3-Compatible storage?

Hi!

We currently use different S3-Compatible storage on the campus: ECS and Ceph.

From the MATLAB doc you can connect to Amazon S3 (or other cloud providers):

setenv('AWS_ACCESS_KEY_ID', 'YOUR_AWS_ACCESS_KEY_ID'); 
setenv('AWS_SECRET_ACCESS_KEY', 'YOUR_AWS_SECRET_ACCESS_KEY');
ds = imageDatastore('s3://bucketname/image_datastore/jpegfiles', ...
'IncludeSubfolders', true, 'LabelSource', 'foldernames'); 
img = ds.readimage(1);
imshow(img)

Is there a way to use our S3 storage by specifying different endpoints, like it's done in the Boto library for example ( Boto Ref ) with the endpoint_url parameter?

Thanks!
