nginx - Docker 私有注册表 /v2/_catalog 不提取 repos 但 /v2/repo/tags/ 有效？

问题描述

我正在尝试在我的私人注册表中列出存储库，但由于未知原因，轮询/v2/_catalog不会返回任何结果，但指定存储库确实会返回结果。

我也可以毫无问题地推拉到这个仓库，所以我很困惑。

// Doesn't work =>
curl -kv -X GET https://registry.example.com/v2/_catalog  --user user:pass

// Does Work =>
curl -kv -X GET https://registry.example.com/v2/nginx/tags/list  --user user:pass

失败的 curl 请求的输出是：

解决方案

我也在寻找这个问题的答案，


   I am trying to get list of repository on jfrog Docker local repository through v2/_catalog. 
   let say repository name: devops and image:mongo:3.6
   jfrog registry url : http://192.168.19.99:8081

   GET API is : curl -k -u test:123test123 -X GET http://192.168.19.99:8081/v2/_catalog

   **Response returns empty** 

   However if put repository name after **v2/reponame/_catalog** then getting correct list of image 
  belongs to given repository.
  e.g: curl -k -u test:123test123 -X GET http://192.168.19.99:8081/v2/devops/_catalog

  {
    "repositories" : [ "mongo" ]
  }

  But i am looking to get through **v2/_catalog** 
  If there any way to make it work using **v2/_catalog**
  However i also tried with Nginx configuration but  **v2/_catalog** returns empty ONLY

  Thanks ```
