How to use Cyber Duck CLI with a custom end point url

Question

I am trying to use Cyberduck CLI to connect to an S3 compatible S3-compatible CEPH API by UKFast (https://www.ukfast.co.uk/cloud-storage.html). It has the same function as Amazon but uses a different url/ server obviously. The connection is via secret key and pass phrase the same as S3. Cyberduck CLI protocols are listed here: https://trac.cyberduck.io/wiki/help/en/howto/cli

I have tried using the below command the windows command prompt. The problem is that Cyberduck auto adds amazon AWS URL. So how do I use all the S3 options with a custom end point?

C:\> duck --list  s3://< Host >/  -i < AccessKey > -p < Secret Key>

Answer 1

The s3:// scheme is reserved for AWS in Cyberduck CLI. If you want to connect to a third party services compatible with the S3 protocol you will need to create a custom connection profile. A connection is a XML property list .cyberduckprofile file that you install, providing another connection scheme. An example of such a profile is the Rackspace profile shipped within the application bundle in Profiles/Rackspace US.cyberduckprofile adding the rackspace:// scheme to connect to OpenStack Swift compatible Rackspace Cloud. You can download one of the other S3 profiles available and use it as a template. Make sure to change at least the Vendor key to the protocol scheme you want to use such as ukfast and put in the service endpoint of UKFast as the value for the Default Hostname key (Which corresponds to s3.amazonaws.com; I cannot find any documentation for the S3 endpoint of UKFast.

When done, verify the new protocol is listed in duck --help. You can then use the command

duck --list ukfast://bucket/ --username <AccessKey> --password <Secret Key>

to list files in a bucket.

You might also want to request UKFast to provide such a profile file for you and other users to make setup simpler. The same connection profile can also be used with Cyberduck.
