## Examples

### <a name="builder"></a> Override the configured builder instance (--builder)

You can also use the `BUILDX_BUILDER` environment variable.

### Enable the default policy

Set `BUILDX_DEFAULT_POLICY=1` to enable Buildx's built-in source policy. The
policy verifies signed tags for images managed by Docker, including BuildKit
builder images and Dockerfile frontends. Untagged digest references and images
outside the managed repositories are allowed unchanged. Tagged references
that also contain a digest still have their release identity verified.
