[сергей кузьмин]

не копировать несуществующие директории (app)
я попробовал на убунту хосте и тоже (хотя и чуть более разумно):

COPY failed: stat /var/lib/docker/tmp/docker-builder598052483/app: no such file or directory

если помогло - я положу в ответы вы отметите решением

[Crowthero]

сергей кузьмин, Да, помогло, спасибо

сообщение об этой ошибке

- нечеткое - на убунту хосте тоже

COPY failed: stat /var/lib/docker/tmp/docker-builder598052483/app: no such file or directory
