In docker composer container raise error : Carbon 1 is deprecated

I tried to run under docker my laravel 5.5 / postgres 9 app and in composer container I got error :

Carbon 1 is deprecated, see how to migrate to Carbon 2. https://carbon.nesbot.com/docs/#api-carbon-2 You can run './vendor/bin/upgrade-carbon' to get help in updating carbon and other frameworks and libraries that depend on it.

    && a2enmod rewrite

    COPY virtualhost.conf /etc/apache2/sites-enabled/000-default.conf

I am not sure which steps have I to take? To add command

RUN ./vendor/bin/upgrade-carbon

In the end of web/Dockerfile.yml file ?

Thanks!
