Dockerfile不会完全复制本地目录中的所有文件。 我不明白他为什么要从后端复制文件夹,但其中没有所有文件。 感谢您的帮助。

错误:无法打开需求文件:[Errno 2]没有这样的文件或目录:'requirements.txt'
答案 0 :(得分:0)
对于您的 Dockerfile ,您的requirements.txt位于后端目录中,并且不在同一级别,因此添加或复制该文件将使其可见:
因此添加:
ADD ./backend/requirements.txt requirements.txt
或
COPY ./backend/requirements.txt requirements.txt
运行之前
RUN pip3 install -r requirements.txt
只需将后端目录复制为:
COPY ./backend /var/www/alinta/
不允许Docker知道您的 requrements.txt 的上下文。使用ADD
或COPY
将指导Docker如何查找文件。
