如何在Docker命令行的Docker注册表中找到带有特定标签的Docker映像？ [英] How can I find a Docker image with a specific tag in Docker registry on the Docker command line?

问题描述

我尝试为Docker映像找到一个特定的标签。如何在命令行上执行此操作？我要避免下载所有图像，然后删除不需要的图像。

I try to locate one specific tag for a Docker image. How can I do it on the command line? I want to avoid downloading all the images and then removing the unneeded ones.

在Ubuntu官方发行版中， https://registry.hub.docker.com/_/ubuntu/ ，有几个标签（已发布），而当我在命令中搜索它时

In the official Ubuntu release, https://registry.hub.docker.com/_/ubuntu/, there are several tags (release for it), while when I search it on the command line,

user@ubuntu:~$ docker search ubuntu | grep ^ubuntu
ubuntu              Official Ubuntu base image                          354
ubuntu-upstart      Upstart is an event-based replacement for ...   7
ubuntufan/ping                                                0
ubuntu-debootstrap                                                   0

也在命令行 search > https://docs.docker.com/engine/reference/commandline/search/ ，不知道

在 docker search 命令中是否可能？

如果我使用原始命令通过 Docker注册表API 进行搜索，然后可以获取信息：

If I use a raw command to search via the Docker registry API, then the information can be fetched:

   $ curl https://registry.hub.docker.com//v1/repositories/ubuntu/tags | python -mjson.tool
   [
    {
        "layer": "ef83896b",
        "name": "latest"
    },
    .....
    {
        "layer": "463ff6be",
        "name": "raring"
    },
    {
        "layer": "195eb90b",
        "name": "saucy"
    },
    {
        "layer": "ef83896b",
        "name": "trusty"
    }
]

推荐答案

As据我所知，CLI不允许在存储库中搜索/列出标签。

As far as I know, the CLI does not allow searching/listing tags in a repository.

但是，如果您知道要使用哪个标签，可以通过添加一个冒号和映像名称： docker pull ubuntu：saucy

But if you know which tag you want, you can pull that explicitly by adding a colon and the image name: docker pull ubuntu:saucy
