Failed to compute cache key: «/app» not found: not found ??

Question

[kieko]

Подскажите в чем проблема ??

Может в самом Docker ?

Dockerfile:

FROM python:3.7-alpine3.7


ENV PYTHONUNBUFFERED 1

COPY ./requirements.txt /requirements.txt

RUN pip install -r /requirements.txt

RUN mkdir /app
WORKDIR /app
COPY ./app /app

RUN adduser -D user

USER user
