I'm using minio in Kubernets and it works great. However, I can't seem to to change the domain and protocol for a pre-signed URL. Minio keeps giving me http://minio.test.svc:9000/delivery/ where as I want https://example.com/delivery. I've tried setting MINIO_DOMIN in the pod but it seems to have not effect; I think I'm misusing this var anyway.
