+### Что можно добавить ?
+### - версионирование тегов
+### - возможность откатываться назад на версию (на нужную версию через ввод переменной)
+### - тестирование кода линтером перед деплоем
+### - возможность деплоя на два окружения (сценарий, когда сначала на стейдж, потом в ручную по тригеру на прод)
