How to remove an image across all nodes in a Docker swarm? -


on local host, can remove image using either docker image rm or docker rmi.

what if current host manager node in docker swarm , wish cascade operation throughout swarm?

when first created docker service, image pulled down on each node in swarm. removing service did not remove image , nodes retain copy of image.

it feels natural if there's way "push" image out nodes there should equally natural way remove them without having ssh every single machine :'( plus, real problem. sooner or later nodes bound have no more disk space!

afaik there no such option of now. each node responsible of own cleanup. there command docker system prune -f can use clear container data.

but tagged images can deleted using docker rmi only. see below issues

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
