Remove a builder instance
### Options
| Name | Description |
| --- | --- |
| `--builder string` | Override the configured builder instance |
| [`--keep-state`](#keep-state) | Keep BuildKit state |
<!---MARKER_GEN_END-->
@ -14,3 +21,10 @@ Remove a builder instance
Removes the specified or current builder. It is a no-op attempting to remove the
default builder.
## Examples
### <a name="keep-state"></a> Keep BuildKit state (--keep-state)
Keep BuildKit state, so it can be reused by a new builder with the same name.
Currently, only supported by the [`docker-container` driver](buildx_create.md#driver).
