Я использовал следующий API:

curl -X POST -H "Content-Type: application/json" --unix-socket /var/run/docker.sock http://v1.27/images/create?fromImage=centos&tag=latest 

Они упомянули, что мне нужно указать tag параметр для предотвращения загрузки всех изображений:

Тег или дайджест. Если при извлечении изображения пусто, это приводит к вытягиванию всех тегов для данного изображения.

Я сделал это и до сих пор он загружает все изображения.
