remove registry

https://stackoverflow.com/questions/43666910/remove-docker-repository-on-remote-docker-registry

1. enable DELETE API:

   1. by config.yml : storage.delete.enabled:true
   2. by env: -e REGISTRY_STORAGE_DELETE_ENABLED=true

2. get the tag reference via GET /v2//manifests/ (don't forget to have Header Accept: application/vnd.docker.distribution.manifest.v2+json).

in response headers, you have docker-content-digest: sha256:xxx

3. send DELETE /v2//manifests/sha256:xxx

4. run garbage collector: bin/registry garbage-collect /etc/docker/registry/config.yml

5. remove files: rm -r /var/lib/registry/docker/registry/v2/repositories//

registry api

GET	/v2/<name>/tags/list	Tags	Fetch the tags under the repository identified by name.
GET	/v2/<name>/manifests/<reference>	Manifest	Fetch the manifest identified by name and reference where reference can be a tag or digest. A HEAD request can also be issued to this endpoint to obtain resource information without receiving all data.

test delete by http

Deleting an Image
An image may be deleted from the registry via its name and reference. A delete may be issued with the following request format:

DELETE /v2//manifests/
For deletes, reference must be a digest or the delete will fail. If the image exists and has been successfully deleted, the following response will be issued:

202 Accepted
Content-Length: None
If the image had already been deleted or did not exist, a 404 Not Found response will be issued instead.

Note When deleting a manifest from a registry version 2.3 or later, the following header must be used when HEAD or GET-ing the manifest to obtain the correct digest to delete:

简单讲 就是 version 2.3 or later,
必须 根据 digest 才可以 删除 image
