如何在docker命令行的docker注册表中找到具有特定标签的docker image？ [英] how can I find docker image with specific tag in docker registry in docker command line?

问题描述

我尝试找到一个特定的码头码头码头图像，我该怎么做在命令行？我尝试避免下载所有内容并删除不需要的图像。

在官方Ubuntu版本 https://registry.hub.docker.com/_/ubuntu/ 有几个标签（为其释放），而当我在命令行中搜索

 用户@ ubuntu：〜$ docker搜索ubuntu | grep ^ ubuntu 
 ubuntu官方Ubuntu基本图像354 
 ubuntu-upstart Upstart是一个基于事件的替代... 7 
 ubuntufan / ping 0 
 ubuntu-debootstrap 0 
  

同样在命令行的帮助下 search https://docs.docker.com/engine/reference/commandline/search/ ，不知道如何工作？

是否可以在 docker search 命令？

如果我使用raw命令通过 docker注册表API ，那么可以获取信息

  $ 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
} 
] 
  

解决方案

如我所知，CLI不允许在存储库中搜索/列出标签。

但是，如果你知道你想要哪个标签，你可以通过添加一个冒号和图像名称： docker pull ubuntu：saucy

I try to locate one specific tag for docker image, how can I do it in command line ? I try to avoid to download all and remove unneeded images.

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

Also in the help of command line search https://docs.docker.com/engine/reference/commandline/search/, no clue how it can work ?

Is it possible in docker search command ?

If I use raw command to search via 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"
    }
]

解决方案

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

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
