如何获取 docker registry v2 上的图像列表 [英] How to get a list of images on docker registry v2

问题描述

我正在使用 docker registry v1，并且我有兴趣迁移到较新的版本 v2.但是我需要一些方法来获取注册表中存在的图像列表；例如使用注册表 v1，我可以对 http://myregistry:5000/v1/search? 执行 GET 请求，结果是:

I'm using docker registry v1 and I'm interested in migrating to the newer version, v2. But I need some way to get a list of images present on registry; for example with registry v1 I can execute a GET request to http://myregistry:5000/v1/search? and the result is:

{
  "num_results": 2,
  "query": "",
  "results": [
    {
      "description": "",
      "name": "deis/router"
    },
    {
      "description": "",
      "name": "deis/database"
    }
  ]
}

但我在官方文档上找不到类似的东西来获取列表注册表上的图像.有人知道在新版本 v2 上的方法吗?

But I can't find on official documentation something similar to get a list of image on registry. Anybody knows a way to do it on new version v2?

推荐答案

对于最新(截至 2015-07-31)版本的 Registry V2，您可以获取 此图像 来自 DockerHub:

For the latest (as of 2015-07-31) version of Registry V2, you can get this image from DockerHub:

docker pull distribution/registry:master

列出所有存储库(有效图像):

List all repositories (effectively images):

curl -X GET https://myregistry:5000/v2/_catalog
> {"repositories":["redis","ubuntu"]}

列出仓库的所有标签:

curl -X GET https://myregistry:5000/v2/ubuntu/tags/list
> {"name":"ubuntu","tags":["14.04"]}

如果注册表需要身份验证，您必须在curl 命令中指定用户名和密码

If the registry needs authentication you have to specify username and password in the curl command

curl -X GET -u <user>:<pass> https://myregistry:5000/v2/_catalog
curl -X GET -u <user>:<pass> https://myregistry:5000/v2/ubuntu/tags/list
