推荐第二种方法 （简单粗暴），第一种凑字数（头晕眼花）
如果需要删除已经上传的镜像，现有两种方法
1.官方推荐版重点内容
1) 更改registry容器内/etc/docker/registry/config.yml文件
storage: delete: enabled: true2) 找出你想要的镜像名称的tag
$ curl -I -X GET <protocol>://<registry_host>/v2/<镜像名>/tags/list3) 拿到digest_hash参数
$ curl --header "Accept: application/vnd.docker.distribution.manifest.v2+json" -I -X GET https://<仓库地址>/v2/<镜像名>/manifests/<tag>如：
$ curl --header "Accept: application/vnd.docker.distribution.manifest.v2+json" -I -X GET https://10.109.252.221:5000/v2/wordpress/manifests/latest4) 复制digest_hash
Docker-Content-Digest: <digest_hash>5) 删除清单
$ curl -I -X DELETE <protocol>://<registry_host>/v2/<repo_name>/manifests/<digest_hash>如：
$ curl -I -X DELETE https://10.109.252.221:5000/v2/wordpress/manifests/sha256:b3a15ef1a1fffb8066d0f0f6d259dc7f646367c0432e3a90062b6064f874f57c6) 删除文件系统内的镜像文件，注意2.4版本以上的registry才有此功能
$ docker exec -it <registry_container_id> bin/registry garbage-collect <path_to_registry_config>如：
$ docker exec registry bin/registry garbage-collect /etc/docker/registry/config.yml2.简易版（推荐）
1.打开镜像的存储目录，如有-V操作打开挂载目录也可以，删除镜像文件夹
$ docker exec <容器名> rm -rf /var/lib/registry/docker/registry/v2/repositories/<镜像名>2.执行垃圾回收操作，注意2.4版本以上的registry才有此功能
