更新
在又看了几次文档后，我意识到我找错了摘要的位置。它不在清单中。
如果你在v2/name/manifests/标签上执行HEAD或GET操作，你会得到一个标题(Docker Content Digest(，其中包含摘要：
Server nginx
Date Sat, 02 Nov 2019 19:01:16 GMT
Content-Type application/vnd.docker.distribution.manifest.v1+prettyjws
Content-Length 2839
Connection keep-alive
Docker-Content-Digest sha256:fcb864bea187b2efbf23d1032052461170fcb482e2dd99f9db5f9a8b538e553d
Docker-Distribution-Api-Version registry/2.0
根据注册表的版本(或者可能与此无关(，在发送GET或HEAD时包含特定标头将导致返回不同的摘要。
此标题为：
Accept: application/vnd.docker.distribution.manifest.v2+json
尽管我正在处理的Registry版本是2.0，但包含此标头会导致为Docker-Content-Digest返回不同的值
无论如何，我尝试了两种变体，但每次获得时我仍然无法删除
{
"errors": [
{
"code": "DIGEST_INVALID",
"message": "provided digest did not match uploaded content"
}
]
}

我有以下清单是为我的图像下载的。我试过这里的每一个字符串来代替摘要，但我没能做到。
有人能指出其中哪一个是Delete命令所需的摘要吗？
我使用的DELETE http请求具有以下公式：
https://my_registry.com/v2/demo/derivedimage/manifests/<whatever the digest is supposed to be here>
这是我每次都会遇到的错误：

答案是如何发送摘要。在我的情况下，我必须包括标题：
Accept: application/vnd.docker.distribution.manifest.v2+json
以在传入标头Docker-Content-Digest中获得正确摘要
其次，我必须包括"；sha256："；在传出的摘要中。示例：
curl -vk -X DELETE https://my_registry.com/v2/demo/derivedimage/manifests/sha256:679b1c1058c1f2dc59a3ee70eed986a88811c0205c8ceea57cec5f22d2c3fbb1
答案是：
