• 先看下官方文档:

• 
  我自己启动registry
  

  docker run -d -p 5000:5000 --name registry --restart=always -v `pwd`/data:/var/lib/registry registry:2
  
  

• 
  push两个镜像
  

  curl -X GET localhost:5000/v2/busybox/tags/list
  
  {"name":"busybox","tags":}
  
  

• 
  删除restful
  

  DELETE /v2/<name>/manifests/<reference>
  
  

For deletes, reference must be a digest or the delete will fail. If the image exists and has been successfully deleted,

• busybox的digest
  {{{
  docker pull localhost:5000/busybox
  Using default tag: latest
  latest: Pulling from busybox

• 我的删除操作

curl -v -X DELETE http://localhost:5000/v2/busybox/manifests/sha256:0fc02bc170932a0d727de2201c65bfe3fe31448dfed6f6bcbc1b37c2668927f5
