Docker hub autobuild在子目录中

Question

我正在尝试使用以下文件夹结构从子目录'app'构建我的Django应用程序的图像。但是，在docker-hub上指定我的构建规则后，请执行以下操作：

• 建立位置：app/Dockerfile
• 建立背景：/

自动构建仍然无法找到requirements.txt

/
├── app/
│   ├── Dockerfile
│   ├── requirements.txt
│   └── (Django files...)
├── nginx/
│   ├── Dockerfile
│   └── (nginx files...)
└── docker-compose.yml

应用程序/ Dockerfile：

FROM python:3.7

ENV PYTHONDONTWRITEBYTECODE 1
ENV PYTHONUNBUFFERED 1

RUN pip install --upgrade pip

RUN mkdir /app
WORKDIR /app
COPY . /app/
RUN pip install -r requirements.txt


# copy entrypoint.sh
COPY ./entrypoint.sh /app/entrypoint.sh

# run entrypoint.sh
ENTRYPOINT ["/app/entrypoint.sh"]

我已经尝试将所有文​​件从app/提取到另一个存储库，并且dockerhub成功构建了映像，没有错误。

如果有人有任何想法，将深表感谢！

试试这个：

• 建立位置：Dockerfile
• 建立背景：app
