Docker在Dockerfile中编译python文件不创建py

Question

我会在Dockerfile中编译python文件（.py）以创建pyc文件，然后删除所有*.py。在

我创建了一个类似tisone的Dockerfile：

FROM python:3.6-alpine
EXPOSE 8000
RUN apk update
RUN apk add --no-cache make linux-headers libffi-dev jpeg-dev zlib-dev
RUN apk add postgresql-dev gcc python3-dev musl-dev

VOLUME /var/lib/cathstudio/data
WORKDIR /var/lib/cathstudio/data

COPY ./requirements.txt .

RUN pip install --upgrade pip
RUN pip install -r requirements.txt
ENV PYTHONUNBUFFERED 1
#ENV PYTHONPATH /var/lib/cathstudio/data

COPY . /var/lib/cathstudio/data

RUN python -m compileall ajaxfuncs/

好吧，当我建立我的形象汇编似乎完成了：

但是当我浏览卷中的文件时，没有pyc文件：

如何在docker构建期间编译python文件以获得pycs？在

提前感谢你

它们已编译，您将在__pycache__文件夹中找到已编译的文件。如果您希望文件与原始文件位于同一目录中，则需要使用：compileall -b

从Docs：
