docker image prune/rm removes in-use image tags #36295
Description
BUG REPORT INFORMATION
Describe the results you received:
Running docker image prune --all --force removes IN-USE images causing locally created images to get lost.
Describe the results you expected:
If a service is running via locally-create-image:1, running docker image prune --all --force SHOULD NOT remove locally-create-image:1
Steps to reproduce the issue:
docker swarm init# simply create a swarmmkdir /test-bugcd /test-bugecho "FROM nginx:1.13.8" > Dockerfile# this is an example, it can be anythingdocker build -t myimage:1 .docker service create --name my-service myimage:1- wait and make sure that your container is running. Check using
docker ps -a, you will see image is listed asmyimage:1 docker image prune --all --force# this is supposed to remove all "unused" imagesdocker service update my-service --force# this can be an update of environmental variables or anything else that causes a container restart.- You will see that the service does not get restarted as there is no
myimage:1image!
