我正在我的Dockerfile中创建一个文件夹,我想给它一个写权限.但是当我尝试这样做时,我得到了许可被拒绝的错误
FROM python:2.7
RUN pip install Flask==0.11.1
RUN useradd -ms /bin/bash admin
USER admin
COPY app /app
WORKDIR /app
RUN chmod 777 /app
CMD ["python","app.py"]
我的错误是
PS C:\Users\Shivanand\Documents\Notes\Praneeth's work\Flask> docker build -t
shivanand3939/test .

如何为Docker容器中的app文件夹授予写入权限
最佳答案
我猜你正在切换到用户“admin”,它没有更改/ app目录权限的所有权.使用“root”用户更改所有权. Dockerfile下面为我工作 –

RUN pip install Flask==0.11.1
RUN useradd -ms /bin/bash admin
COPY app /app
WORKDIR /app
RUN chown -R admin:admin /app
RUN chmod 755 /app
USER admin
CMD ["python","app.py"]
PS – 尽量摆脱“777”的许可.我暂时试图在Dockerfile上面做这件事.
