S3 support for other than AWS, but compatible, repositories?

[glemoine62]

I understand leafmap.s3_* functions (in common) are specific to AWS buckets. I would like to integrate data from a non-AWS repository which is fully compatible with the S3 standard. E.g. I can use boto3 to list_objects, etc. Since leafmap uses boto3 for S3 access, it should in principle be possible to use alternative repositories, e.g. by passing endpoint_url to the S3 session. Is this understanding correct?

Yes, it should. It it doesn't work, please feel free to report an issue and provide a code snippet that can reproduce the issue

Do you happen to know how to pass in the endpoint_url? As an os.environ['ENDPOINT_URL'] (does not seem to work) or as one of the **kwargs?

[glemoine62]

Only the S3 functions that allow client_args to be passed work. I can do

endpoint_properties = {}
endpoint_properties['endpoint_url'] = "https://url_of_alt_endpoint"
leafmap.s3_get_object('bucket_name', 'key', client_args=endpoint_properties)

but not leafmap.list_objects() which does not pass on any arguments to boto3.client() internally.

This has been fixed in #734. Will release a new version later this week.
