<!---MARKER_GEN_END-->
## Description
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.
## Examples
### <a name="builder"></a> Override the configured builder instance (--builder)
