How to delete docker images from docker hub using a shell script.
I want to delete all images from docker hub older than past 50 days of a private docker hub account.
Any ideas? Which tools to use while creating and running this shell script from either through Jenkins or bash terminal.
I'm thinking of using curl to achieve my goal.
Below script will delete all images in all repositories of your docker hub account which are older than 50 days.
#!/bin/bash
#Script will delete all images in all repositories of your docker hub account which are older than 50 days
set -e
set username and password
UNAME="YOUR_USERNAME"
UPASS="YOUR_PASSWORD"
get token to be able to talk to Docker Hub
TOKEN=$(curl -s -H "Content-Type: application/json" -X POST -d '{"username": "'${UNAME}'", "password": "'${UPASS}'"}' https://hub.docker.com/v2/users/login/ | jq -r .token)
get list of namespaces accessible by user (not in use right now)
#NAMESPACES=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/namespaces/ | jq -r '.namespaces|.[]')
#echo $TOKEN
echo
get list of repos for that user account
echo "List of Repositories in ${UNAME} Docker Hub account"
sleep 5
REPO_LIST=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${UNAME}/?page_size=10000 | jq -r '.results|.[]|.name')
echo $REPO_LIST
echo
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=10000 | 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 list of all docker images
echo
echo "List of all docker images in ${UNAME} Docker Hub account"
sleep 10
for i in ${FULL_IMAGE_LIST}
do
echo ${i}
done
sleep 10
echo
echo "Identifying and deleting images which are older than 50 days in ${UNAME} docker hub account"

Note!!! Please un-comment below line if you wanna perform operation on all repositories of your Docker Hub account

for i in randomRepo

#for i in mynginx mykibana

My version for a specific repository in a specific organization.
You should tweak the pagination ('?page=2000') to grab the old images you are interested in.
Then run it in a bash loop.
while true; do bash delete_old_images.sh; done
