How can I list all tags for a Docker image on a remote registry?

by

Update: sadly this solution will no longer work because Docker has deprecated the v1 API.

I got the answer from here . Thanks a lot! 🙂

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 '}' '\n'  | awk -F: '{print $3}'

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 '}' '\n'  | awk -F: '{print $3}'`

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

echo "${tags}"

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).

Usage:

dockertags ubuntu —> list all tags of ubuntu

dockertags php apache —> list all php tags php containing ‘apache’
