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

Question

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

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

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'
