docker image prune -a

[FDiskas]

I would like to reclaim more space. In my case it was like 4GB after couple month of daily deploys
More info apocas/dockerode#429

docker system df

TYPE                TOTAL               ACTIVE              SIZE                RECLAIMABLE
Images              18                  6                   5.501GB             4.639GB (84%)

Local Volumes       3                   3                   50.92MB             0B (0%)

And after pruning with flag -a

TYPE                TOTAL               ACTIVE              SIZE                RECLAIMABLE

Coverage remained the same at 87.462% when pulling 6f85cac on FDiskas:patch-1 into 5725c91 on exoframejs:master.

This changes the behavior quite a bit. It should be behind a flag IMO 🤔

[FDiskas]

This is what I'm thinking:
exoframe is not going to mimic/forward docker commands with all his additional params.
the same as exoframe rm container - impossible to remove multiple containers at once - just because it's not going to replace docker functionality - but rather then a helper to do some common stuff without actually connecting to the server. Lets allow exoframe do its job (cleanup as much as possible) - on dedicated server size is matter. But in other cases like if end user is very delicate - he can cleanup connected to the server and using docker with all params or without params as he wants.

[yamalight]

I'm not saying exoframe should mimic all docker commands, I'm just saying this particular one should be behind an opt-in flag.
Removing all dangling images has quite a severe impact (on docker builds, starting services, etc) - so IMO it shouldn't be default, it needs a flag.

[FDiskas]

This flag should look the same -a?

[yamalight]

@FDiskas yeah, --all (short -a) would be perfect
