问题描述
我正在为docker编写API客户端，因此很难使用注册表API。我正在尝试从注册表中删除图片，但是我一直收到此错误
I'm writing an API client for docker and the registry API is difficult to work with. I'm trying to delete an image from the registry however I keep getting this error
[ { code: 'UNSUPPORTED', message: 'The operation is unsupported.' } ]
获取此文件的步骤如下，
My steps to get this are as follows,
> GET http://localhost:5000/v2/
> registry/2.0
> registry/2.0
> GET http://localhost:5000/v2/_catalog/
> { repositories: [ 'alpine' ] }
> GET http://localhost:5000/v2/alpine/tags/list
> { name: 'alpine', tags: [ 'latest' ] }
> HEAD http://localhost:5000/v2/alpine/manifests/latest
> sha256:df73ed0973f15f40496c148330f9b559f0a5583c03f6ac8d26adadf6f4690aff
> DELETE http://localhost:5000/v2/alpine/manifests/sha256:df73ed0973f15f40496c148330f9b559f0a5583c03f6ac8d26adadf6f4690aff
[ { code: 'UNSUPPORTED', message: 'The operation is unsupported.' } ]
编辑
由于我发现 REGISTRY_STORAGE_DELETE_ENABLED 变量。
我现在像这样运行注册表容器，
I now run the registry container like so,
docker run -d -p 5000:5000 -e REGISTRY_STORAGE_DELETE_ENABLED=true --name registry2 registry
这会产生新错误，
[ { code: 'MANIFEST_UNKNOWN', message: 'manifest unknown' } ]
显然是 UNSUPPORTED 错误，确实意味着该特定功能已被禁用。
Clearly the UNSUPPORTED error, really meant that the particular feature was disabled.
但是我读到的所有内容都表明删除清单的实体引用（来自HEAD请求的摘要）应删除存储库。我只是想使私有注册表中的存储库无法访问，我认为已将其删除。
However everything I read says that deleting the manifest's entity reference (the digest from the HEAD request) should remove the repository. I just want to make a repository in my private registry unreachable, I consider that deleted.
推荐答案
即使这是一个老问题：解决方案也很简单。
Even if this is an old question: The solution is simple.
DELETE http://localhost:5000/v2/alpine/manifests/sha256:df73ed0973f15f40496c148330f9b559f0a5583c03f6ac8d26adadf6f4690aff
是错误的，因为摘要以 sha256：为前缀。简单地删除前缀，然后可以删除：
is wrong because the digest is prefixed with sha256:. Simple remove the prefix and then a delete is possible:
DELETE http://localhost:5000/v2/alpine/manifests/df73ed0973f15f40496c148330f9b559f0a5583c03f6ac8d26adadf6f4690aff
