从Docker Registry v2删除图像 [英] delete image from docker registry v2

问题描述

Docker Registry v2具有用于删除映像的API端点

the Docker Registry v2 has an API endpoint to delete an image

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

https://github.com/docker/distribution/blob/master/docs/spec/api.md#deleting-an-image

但是文档说:

对于删除，引用必须是摘要，否则删除将失败.

For deletes, reference must be a digest or the delete will fail.

实际上，使用标记无效，并返回 405不支持的操作

Indeed, using a tag does not work and returns a 405 Operation Not Supported

问题是，似乎没有任何端点可以获取图像的 digest .

The problem is, there doesn't seem to be any endpoint to get the digest of an image.

列出图像的端点，而标签仅列出这些图像.

The endpoints to list images, and tags only list those.

尝试使用

GET /v2/<name>/manifests/<reference>    

使用标记作为< reference> ，我看到 Docker-Content-Digest 标头设置了 digest是文档所说的

using the tag as <reference>I see that a Docker-Content-Digest header is set with a digest which the doc says is

Docker-Content-Digest:目标内容的摘要请求.

Docker-Content-Digest: Digest of the targeted content for the request.

体内包含一堆 blobSum:< digest>

如果我尝试使用标题摘要"值，则使用

If I try using the Header digest value, with

GET /v2/<name>/manifests/<reference>

和 digest 作为< reference> ，我得到 404 .

摘要如下所示: sha256:6367f164d92eb69a7f4bf4cab173e6b21398f94984ea1e1d8addc1863f4ed502

，我尝试使用和不使用 sha256 前缀.但没有运气

and I tried with and without the sha256 prefix. but no luck

那我应该如何获取要删除的图像的摘要，将其删除?

So how am I supposed to get the digest of the image I want to delete, to delete it?

推荐答案

curl -u login:password -H "Accept: application/vnd.docker.distribution.manifest.v2+json" -X GET https://registry.private.com/v2/<name>/manifests/<tag>

json>配置>摘要

json > config > digest
