gofabric8 doesn't respect docker-registry switch

[gaord]

I try to deploy platform in kubernetes cluster with a private docker registry as below:
gofabric8 deploy -y -n fabric8 --pv=false --ingress=false --http=true --package platform --docker-registry https://registry.local/fabric8

During installing it picks up the switch anyway. However, pods are deployed with the public docker registry.
Loading fabric8 docker images from docker registry: https://registry.local/fabric8

gofabric8 version info:
gofabric8, version 0.4.176 (branch: 'master', revision: '22de39d49')

Hope it could be fixed anyway. Thanks
