Get the list of images and tags for a Docker Hub user account.

dockerhub-v2-api-user.sh

#!/bin/bash

# Example for the Docker Hub V2 API
# Returns all imagas and tags associated with a Docker Hub user account.
# Requires 'jq': https://stedolan.github.io/jq/

# set username and password
UNAME=""
UPASS=""

# -------

set -e
echo

# aquire token
TOKEN=$(curl -s -H "Content-Type: application/json" -X POST -d '{"username": "'${UNAME}'", "password": "'${UPASS}'"}' https://hub.docker.com/v2/users/login/ | jq -r .token)

# get list of repositories for the user account
REPO_LIST=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${UNAME}/?page_size=100 | jq -r '.results|.[]|.name')

# build a list of all images & tags
for i in ${REPO_LIST}
do
  # get tags for repo
  IMAGE_TAGS=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${UNAME}/${i}/tags/?page_size=100 | jq -r '.results|.[]|.name')

  # build a list of images from tags
  for j in ${IMAGE_TAGS}
  do
    # add each tag to list
    FULL_IMAGE_LIST="${FULL_IMAGE_LIST} ${UNAME}/${i}:${j}"
  done
done

# output
for i in ${FULL_IMAGE_LIST}
do
  echo ${i}
done

In case anyone here has trouble. In the above example the variable ${i} was saving with a new line \r at the end. So the second curl to get tags was not returning anything. Here is the fix:

# build a list of all images & tags
for i in ${REPO_LIST}
do
  cr=$'\r'
  i="${i%$cr}"
  # get tags for repo
  IMAGE_TAGS=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${UNAME}/${i}/tags/?page_size=100 | jq -r '.results|.[]|.name')

👍 Thanks!
I would sort the output this way:

for i in ${FULL_IMAGE_LIST}
do
  echo ${i} >> temp.txt
done

cat temp.txt | sort -n

rm temp.txt

Not perfect but it's a bit more readable for huge repos like library/mongo

Anyone have any luck getting image manifests from hub.docker.com API ?

Documented here:
https://docs.docker.com/registry/spec/api/#manifest

Tried this:

https://hub.docker.com/v2/repositories/${UNAME}/${i}/manifests/${tag}

like could be deduced from the working gist above, but unable to get it to work.

I had to use Docker Hub API v2 for private repo in order to get list of all tags, example is here if anyone needs it:

@Jack-qing. you need jq. you can install one from brew (brew install jq). let's see if there is any problem after you have jq

Where can I find the official documentation for this docker hub v2 api?

Just to add here: This will fetch any user's public repos irrespective of the authorised user.

Worked like wonders, for my naive repos <3

There is a page_size parameter specified in the REST API call which means only 100 images at a time will get listed down. What if I want to list down all images?

thanks for the script
