В зависимости от ваших требований можно включить ssl-passthrough, не забыв при этом поменять listen port в приложении и поправить раздел rules у ingress, однако я столкнулся с проблемой, что при такой конфигурации не работает > 1 пода - трафик round-robin отправляется на поды и возможны потери сессии.

При желании можно применить и другие CRD console<type> из репозитория. Консоль подхватит и их.
