docker image prune -a -f
Using a very old Unix trick:
yes | ./launcher cleanup
Your answer is a typical example of a superficial answer from a mid-level specialist.
In particular, I, and many other users, want to delete only orphaned images and do not want to delete containers that are currently stopped for a reason.
Another superficial specialist of your level will thoughtlessly enter your command and delete images of his customer's stopped containers, which he was not even aware of.
I'm genuinely sorry - I didn't realize you're sniffing your own farts here. I mistook this site for a real discussion forum, and this is merely a ploy to sell your services. My bad.
Sincerely, a low-level specialist.
