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.

  • HUB_TOKEN=$(curl -s -H "Content-Type: application/json" -X POST -d '{"username": "'${HUB_USERNAME}'", "password": "'${HUB_PASSWORD}'"}' hub.docker.com/v2/users/login | jq -r .token) echo $HUB_TOKEN Commented Jun 18, 2020 at 6:26
  • curl -i -X DELETE \ -H "Accept: application/json" \ -H "Authorization: JWT $HUB_TOKEN" \ hub.docker.com/v2/repositories/<HUB_USERNAME>/… i have above two commands to delete a image of "myes" repository in my docker hub but that image didn't got deleted from my docker hub and http response was "HTTP/1.1 301 MOVED PERMANENTLY". Is this syntax correct to delete a image or what else needs to be done to get the result. Commented Jun 18, 2020 at 6:33
  • curl -si -L -X DELETE -H "Authorization: JWT ${HUB_TOKEN}" hub.docker.com/v2/repositories/<username>/<repo name>/tags/<tag id> this command did the trick for me Commented Jun 18, 2020 at 16:20
  • We can also used the shell-script in link below and modified it to our purpose. success.docker.com/article/… Commented Jun 21, 2020 at 5:06

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" sleep 10 # Note!!!

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

./delete_old_images.sh

#!/bin/bash #Script will delete all images in all repositories of your docker hub account which are older than 50 days set -e UNAME="user" UPASS="password" ORGANIZATIONNAME="user" REPOSITORY="repo" # 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) echo echo "Identifying and deleting images which are older than 50 days in ${ORGANIZATIONNAME} docker hub account" # get tags for repo echo echo "Looping Through ${REPOSITORY} repository in ${UNAME} account" IMAGE_TAGS=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${ORGANIZATIONNAME}/${REPOSITORY}/tags/?'page=2000' | jq -r '.results|.[]|.name') # build a list of images from tags for j in ${IMAGE_TAGS} do echo # add last_updated_time updated_time=$(curl -s -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${ORGANIZATIONNAME}/${REPOSITORY}/tags/${j}/?page_size=10000 | jq -r '.last_updated') echo $updated_time datetime=$updated_time timeago='50 days ago' dtSec=$(date --date "$datetime" +'%s') taSec=$(date --date "$timeago" +'%s') echo "INFO: dtSec=$dtSec, taSec=$taSec" if [ $dtSec -lt $taSec ]; then echo "This image ${UNAME}/${REPOSITORY}:${j} is older than 50 days, deleting this image" ## Please uncomment below line to delete docker hub images of docker hub repositories # curl -s -X DELETE -H "Authorization: JWT ${TOKEN}" https://hub.docker.com/v2/repositories/${ORGANIZATIONNAME}/${REPOSITORY}/tags/${j}/ else echo "This image ${UNAME}/${REPOSITORY}:${j} is within 50 days time range, keep this image" fi done echo "Script execution ends"
