Run Docker registry in a container

docker run -d -p 5000:5000 \
  -v $(pwd)/config.yml:/etc/docker/registry/config.yml \
  -v $(pwd)/certs:/certs \
  --name=registry registry:2

Tag some image to push to the registry

docker tag alpine:3.5 <docker host ip running registry>:5000/alpine:3.5 docker push <docker host ip running registry>:5000/alpine:3.5

maintenance: uploadpurging: enabled: true age: 168h interval: 24h dryrun: false

is turned on?
