docker-buildx-prune - Remove build cache

docker buildx prune

Clears the build cache of the selected builder.

You can finely control what cache data is kept using:

•
The --filter=until=<duration> flag to keep images that have been used in the last <duration> time.

<duration> is a duration string, e.g. 24h or 2h30m, with allowable
units of (h)ours, (m)inutes and (s)econds.

•
The --keep-storage=<size> flag to keep <size> bytes of data in the cache.

<size> is a human-readable memory string, e.g. 128mb, 2gb, etc. Units
are case-insensitive.

•
The --all flag to allow clearing internal helper images and frontend images set using the #syntax= directive or the BUILDKIT_SYNTAX build argument.

-a, --all[=false] Include internal/frontend images

--filter= Provide filter values (e.g., "until=24h")

-f, --force[=false] Do not prompt for confirmation

-h, --help[=false] help for prune

--keep-storage=0 Amount of disk space to keep for cache

--verbose[=false] Provide a more verbose output

--builder="" Override the configured builder instance

### Override the configured builder instance (--builder) {#builder}
Same as [`buildx --builder`](/reference/cli/docker/buildx/#builder).
