Hi, Docker changed the old docker-registry project to docker-distribution and its API to v2. It now uses librados instead of radosgw to save data. In some ceph installations it is easier to get access to radosgw than to the cluster, so I've made a pull request to add radosgw support, it would be great if you test it. https://hub.docker.com/r/lorieri/docker-distribution-generic-s3/ Note: if you already use the old docker-registry you must create another bucket and push the images again, the API changed to v2. There is a shellscript to help https://github.com/docker/migrator How I tested it: docker run -d -p 5000:5000 -e "REGISTRY_STORAGE=s3" \ -e "REGISTRY_STORAGE_S3_REGION=generic" \ -e "REGISTRY_STORAGE_S3_REGIONENDPOINT=http://myradosgw.mydomain.com" \ -e "REGISTRY_STORAGE_S3_BUCKET=registry" \ -e "REGISTRY_STORAGE_S3_ACCESSKEY=XXXXXXX" \ -e "REGISTRY_STORAGE_S3_SECRETKEY=XXXXXXX" \ -e "REGISTRY_STORAGE_S3_SECURE=false" \ -e "REGISTRY_STORAGE_S3_ENCRYPT=false" \ -e "REGISTRY_STORAGE_S3_REGIONSUPPORTSHEAD=false" \ lorieri/docker-distribution-generic-s3 thanks, -lorieri _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
