Hello,

we have a similar issue with the 'until' filter.

It was working before the recent 18.09 engine release.

Steps to reproduce the issue:

root@host:~# docker system prune --all --force --filter 'until=2h'  
Error response from daemon: failed to prune build cache: Invalid filter 'until'

[ArmaneS]

Hi,
the same issue appears to be when try running with the following commands:

docker system prune --force --filter 'label!=key=value'
Error response from daemon: Invalid filter 'label!'

Also, when try to prune with the filter like "until=2018-10-10" it does not remove old images.

This should be resolved by moby/moby#38238, which will be included in 18.09.1 through docker-archive/engine#122

[bradwilson]

The 'until' filter does not appear to be fixed in 18.09.1.

[thaJeztah]

@bradwilson what are you seeing on 18.09.1? I just tried reproducing the issue, but it succeeded on 18.09.1;

docker system prune --filter 'until=2h'
WARNING! This will remove:
        - all stopped containers
        - all networks not used by at least one container
        - all dangling images
        - all dangling build cache
        - Elements to be pruned will be filtered with:
        - label={"until":{"2h":true}}

Ah, I realize now that it works in prune, but not in docker images, which is a shame since testing a filter in list before using it to delete makes the operation safer.

[thaJeztah]

Ah, yes docker image ls does not have a filter based on time yet. Feel free to open a new ticket for that though, so that it can be discussed.

There a separate issue for adding a --dry-run option on docker system prune; moby/moby#30623 #763

[thaJeztah]

Closing this ticket, because the issue originally reported here is fixed 👍

[michaelschem]

This seems to either be not fixed or broken again.

docker system prune --filter "label=foobar" --all --force

does not work
