Delete Tag: The operation is unsupported.

[pcace]

HI there, waht can be the reason not to be able to delete images via the ui?
whenever i click on delete on a tag, i get this error Message:

{"errors":[{"code":"UNSUPPORTED","message":"The operation is unsupported."}]}
I run the docker-registry-ui with these env variables:

SINGLE_REGISTRY=true
REGISTRY_TITLE=Docker Registry UI
DELETE_IMAGES=true
SHOW_CONTENT_DIGEST=true
NGINX_PROXY_PASS_URL=http://registry:5000
SHOW_CATALOG_NB_TAGS=true
CATALOG_MIN_BRANCHES=1
CATALOG_MAX_BRANCHES=1
TAGLIST_PAGE_SIZE=100
REGISTRY_SECURED=false
CATALOG_ELEMENTS_LIMIT=1000
REGISTRY_STORAGE_DELETE_ENABLED=true

My private docker registry configuration

version: 0.1
log:
  fields:
    service: registry
storage:
  cache:
    blobdescriptor: inmemory
  filesystem:
    rootdirectory: /var/lib/registry

Having the same problem

I found the solution:

The error code 405 indicates that deletion is not enabled for the registry or the registry is configured to be a pull-through cache as stated in the documentation.

So you have to enable deletion on the registry by doing one of the following things:

• If you configure your registry using env variables in the docker-compose.yml set the variable:
  REGISTRY_STORAGE_DELETE_ENABLED: 'true'
• If you use a config.yml (like you do) add the following piece of code to your config.yml which is documented here

delete:
 enabled: true

After that restart the container and it should work.

Please keep in mind: This does not delete the data from the registry as far as I understood see #147 for more information

Thanks a lot! That seems to fix it for me!
