如何在远程注册表上列出 Docker 映像的所有标签? [英] How can I list all tags for a Docker image on a remote registry?

问题描述

如何使用 CLI(首选)或 curl 在远程 Docker 注册表中列出 Docker 镜像的所有标签?

How can I list all tags of a Docker image on a remote Docker registry using the CLI (preferred) or curl?

最好不要从远程注册表中提取所有版本.我只想列出标签.

Preferably without pulling all versions from the remote registry. I just want to list the tags.

推荐答案

我从 此处.非常感谢！:)

I got the answer from here . Thanks a lot! :)

单行脚本:(找到debian的所有标签)

Just one-line-script:(find all the tags of debian)

wget -q https://registry.hub.docker.com/v1/repositories/debian/tags -O -  | sed -e 's/[][]//g' -e 's/"//g' -e 's/ //g' | tr '}' '
'  | awk -F: '{print $3}'

更新感谢@degelf 的建议.这是shell脚本.

UPDATE Thanks for @degelf's advice. Here is the shell script.

#!/bin/bash

if [ $# -lt 1 ]
then
cat << HELP

dockertags  --  list all tags for a Docker image on a remote registry.

EXAMPLE: 
    - list all tags for ubuntu:
       dockertags ubuntu

    - list all php tags containing apache:
       dockertags php apache

HELP
fi

image="$1"
tags=`wget -q https://registry.hub.docker.com/v1/repositories/${image}/tags -O -  | sed -e 's/[][]//g' -e 's/"//g' -e 's/ //g' | tr '}' '
'  | awk -F: '{print $3}'`

if [ -n "$2" ]
then
    tags=` echo "${tags}" | grep "$2" `
fi

echo "${tags}"

您可以在/usr/local/bin 下创建一个新文件名 dockertags(或将 PATH env 添加到您的 .bashrc/.zshrc)，然后将代码放入其中.然后添加可执行权限(chmod +x dockertags).

You can just create a new file name, dockertags, under /usr/local/bin (or add a PATH env to your .bashrc/.zshrc), and put that code in it. Then add the executable permissions(chmod +x dockertags).

用法:

dockertags ubuntu ---> 列出ubuntu的所有标签

dockertags ubuntu ---> list all tags of ubuntu

dockertags php apache ---> 列出所有包含'apache'的php标签

dockertags php apache ---> list all php tags php containing 'apache'
