+# como borrar tags
+
+
+
+While accepted answer is a good end solution, there is a simpler way to achieve this, without using the API: just delete the tag dirs manually from registry storage and then run the garbage-collect.
+
+First identify where your registry stores the data. By default it goes to /var/lib/registry dir inside the container, but its probably binded to your host one way or the other. I am using docker-compose with data volume so in my case its located at: /var/lib/docker/volumes/registry_data/_data/registry.
+
+You'll find dirs named as your project tags in there, relative to above path: v2/repositories/<repo_name>/_manifests/tags
+
+Just delete the dirs which tag you dont want anymore. For example:
+
+rm -rf /var/lib/docker/volumes/registry_data/_data/registry/v2/repositories/I5/_manifests/tags/T12
+
+Once you are done with that, run the garbage-collect:
+
+docker exec <registry_container_name> registry garbage-collect /etc/docker/registry/config.yml --delete-untagged
+
+Your registry config file may be in some other path, but this is the default. Read more about the garbage collector from docs, but the gist is: the registry binary inside the container includes a garbage-collect command, but you have to run it yourself. Of course you can always let the crontab run it for you.
