Is it possible to run Docker in Docker as a service container? | Dagger | Page 1

I saw this article featuring an example that is running docker-in-docker as a service container.

I tried to do the same but it didn't work, probably because the nested container isn't running in privileged mode?

// Docker in docker
func (m *Treasury) Dind() *dagger.Service {
    // https://hub.docker.com/_/docker
    return dag.Container().
        From("docker:dind").
        WithExposedPort(2375).
        AsService()
}
