Hi,
delete_docker_registry_image --image localhost:5000/cs/hello-world:8.0
CRITICAL [2016-03-02 21:26:01,938] No repository 'localhost:5000/cs/hello-world:8.0' found in repositories directory /var/lib/docker/repositories
I can`t find REGISTRY_DATA_DIR,pls help...

[Kevin Burnett]

you want to omit the localhost:5000/ in the image reference. ls
/var/lib/docker/repositories
to get an idea of the structure.

At path of /var/lib/docker/
containers devicemapper graph linkgraph.db repositories-devicemapper tmp trust volumes
no repositories folder...
Any where wrong?

oh, yeah, that's the docker graph location on your host, not your registry data directory. your registry data is wherever you bindmounted it to when you started up your registry. i start my registry with a docker-compose.yml like this:

registry:
  # restart: always
  image: registry:2.1.1
  ports:
    - 5000:5000
  environment:
    REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY: /var/lib/registry
  volumes:
    - /opt/registry_data:/var/lib/registry

i'm tell the registry to put its data in the container at /var/lib/registry (i think this is default now, so you can probably omit the REGISTRY_STORAGE_FILESYSTEM_ROOTDIRECTORY line) and then i mount /opt/registry on the host as the volume which persists /var/lib/registry inside the countainer. perhaps you used another location on the host instead of /opt/registry.

if you're still not sure where you put it, you could try this:

locate v2/repositories

Thanks @burnettk

>docker pull private-registry-server/app/ctcrawler:1.0
show some logs:

Pulling repository private-registry-server/app/ctcrawler

3.Try push client images tags:
>docker pull private-registry-server/app/ctcrawler:1.0
Success

4.delete again:

i think you're experiencing the issue described in #10. if this is true, i
just fixed it, so it would be helpful if you could install the new version,
try again, and confirm that it's working now.
