Не удалось разрешить имя изображения: краткое имя "caddy:2-alpine"

Я получаю эту ошибку при запуске docker-compose up:

ERROR: failed to resolve image name: short-name "caddy:2-alpine" did not resolve to an alias and no unqualified-search registries are defined in "/etc/containers/registries.conf"

Вот мой файл docker-compose.yaml:
