尝试获取 Docker Hub 目录时范围不足

Question

我正在尝试获取 Docker 中心的目录列表，但到目前为止我只是收到一个错误响应。我的理解是我需要通过目录请求传递不记名令牌，所以我首先获取具有相关范围的令牌：

curl -u "username:password "https://auth.docker.io/token?service=registry.docker.io&scope=registry:catalog:*"

（这是使用我的 Docker Hub 帐户中的 username/password）

然后我将返回的令牌传递给注册表：

curl -vL -H "Authorization: Bearer eyJhbGciOiJFUzI1NiIsInR5cCI6I(...)" https://registry-1.docker.io/v2/_catalog

为了响应该请求，我得到：

{"errors":[{"code":"UNAUTHORIZED","message":"authentication required","detail":[{"Type":"registry","Name":"catalog","Action":"*"}]}]}

...这似乎是要我返回并获得我在上面输入的 URL 的授权。

这应该可行吗？如果是这样，我错过了什么？

Answer 1

我遇到了同样的问题，在 docker 支持下提出了这个问题并得到了以下答案， "The catalog endpoint does not work against Docker Hub because that endpoint actually lists all the repositories on a Registry, and we disabled it as it would list all repositories on Docker Hub."

Answer 2

如果您需要用户名或组织的存储库信息，另一种方法是使用 V1 api。这样做的问题是您需要根据可用的存储库数量进行多次调用。

以下命令将为给定用户名提供可用的存储库：

curl -k -H "Authorization: Basic <encripted username:password>" -H "Accept: application/json" -X GET "https://index.docker.io/v1/search?q=<username>&n=100"

此处 q 是查询，n 是每页要返回的项目数。

通过将 repo 作为参数传递，可以根据您需要的数据进行另一个调用。
