我正在Dockerfile中创建一个文件夹,我想给它一个写许可权。但是我尝试执行此操作时遇到权限拒绝错误
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

Sending build context to Docker daemon 209.9kB Step 1/8 : FROM python:2.7 ---> 8a90a66b719a Step 2/8 : RUN pip install Flask==0.11.1 ---> Using cache ---> 6dc114bd7cf1 Step 3/8 : RUN useradd -ms /bin/bash admin ---> Using cache ---> 1cfdb6eea7dc Step 4/8 : USER admin ---> Using cache ---> 27c5e8b09f15 Step 5/8 : COPY app /app ---> Using cache ---> 5d628573b24f Step 6/8 : WORKDIR /app ---> Using cache ---> 351e19a5a007 Step 7/8 : RUN chmod 777 /app ---> Running in aaad3c79e0f4 **chmod: changing permissions of ‘/app’: Operation not permitted The command '/bin/sh -c chmod 777 /app' returned a non-zero code: 1**
如何授予对Docker容器内的app文件夹的写权限
我猜您正在切换到没有所有权来更改/ app目录权限的用户“ admin”。使用“ root”用户更改所有权。在Dockerfile下面为我工作-
FROM python:2.7 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-尝试摆脱“ 777”权限。我暂时尝试在Dockerfile上面做到这一点。
