Rados store driver

Hi,

I want to configure a registry with “Ceph rados storage driver”, but after start the registry with “docker run -d -p 5000:5000 --restart=always --name registry -v pwd/config.yml:/etc/docker/registry/config.yml registry:2”

I got this error in the dockers logs:

“panic: StorageDriver not registered: rados”

Someone know why I got that error o whats mean?

This is my configuration file for the registry:

version: 0.1
log:
level: debug
formatter: text
fields:
service: registry
storage:
cache:
blobdescriptor: inmemory
rados:
poolname: docker_rep

http:
addr: :5000
headers:

health:
storagedriver:

interval: 10s

Regards.
Pedro.
