我有一个Docker dev设置,可以在带有Hyper-V的Mac和Windows上运行良好,但不能在带有WSL2的Windows上运行。当Python试图执行makedirs
命令时,我们得到一个PermissionError: [Errno 13] Permission denied
错误。例如,当尝试制作/code/static
时,我们会得到:
PermissionError: [Errno 13] Permission denied: '/code/static'
类似于Django的makemigrations
命令,它试图在/code/website/migrations
上创建一个迁移目录,我们得到:
PermissionError: [Errno 13] Permission denied: '/code/website/migrations'
但是我们的Dockerfile明确地给了apache
用户访问/code/
文件夹的权限。下面是完整的Dockerfile:
# All Dockerfiles must start with a 'FROM' instruction, which specifies a base image
# See: https://docs.docker.com/engine/reference/builder/#format
# Note, some online sources say that you should put FROM django here (e.g., https://runnable.com/docker/python/dockerize-your-django-application)
# but, in fact, you should NOT do this according to the official docs (as this approach has been deprecated).
# See: https://hub.docker.com/_/django/
FROM python:3.8
# Sometimes we get warnings about old pip, so take care of that here
RUN pip install --upgrade pip
# See: https://www.quora.com/How-does-one-install-pip-in-a-Docker-container-using-a-Dockerfile
RUN apt-get update && apt-get --assume-yes install imagemagick ghostscript sqlite3
# The ENV instruction sets the environment variable <key> to the <value> in ENV <key> <value>.
# See: https://docs.docker.com/engine/reference/builder/#environment-replacement
# In this case, we are setting the stdout/stderr streams in Python to be unbuffered
ENV PYTHONUNBUFFERED 1
#Create a system user which we'll use later.
#We're using the 'apache' user since that's what we're trying to map
#outside the container -- it could be called anything, but apache is convenient
RUN useradd -u 48 apache
RUN groupmod -g 48 apache
# The RUN instruction will execute any commands in a new layer on top of the current image and commit the results.
# The resulting committed image will be used for the next step in the Dockerfile.
# See: https://docs.docker.com/engine/reference/builder/#run
RUN mkdir /code
# The WORKDIR instruction sets the working directory for any RUN, CMD, ENTRYPOINT, COPY and ADD instructions
# that follow it in the Dockerfile. If the WORKDIR doesn’t exist, it will be created even if it’s not used
# in any subsequent Dockerfile instruction.
# See: https://docs.docker.com/engine/reference/builder/#workdir
WORKDIR /code
#COPY the requirements.txt into the docker container
# As an fyi: Layering RUN instructions and generating commits conforms to the core concepts
# of Docker where commits are cheap and containers can be created from any point in an image’s history, much like source control.
# See: https://docs.docker.com/engine/reference/builder/#run
COPY requirements.txt /code/
RUN pip3.8 install -r requirements.txt
## TEMP related to: https://github.com/jonfroehlich/makeabilitylabwebsite/issues/866
#RUN pip install django-ckeditor
# Our local user needs write access to a website and static files
RUN chown -R apache /code/
# Despite the above, still getting permission errors on WSL2
# -- PermissionError: [Errno 13] Permission denied: '/code/static'
# -- PermissionError: [Errno 13] Permission denied: '/code/website/migrations'
# RUN chown apache:apache -R /code/
COPY . /code/
#Run the process as our local user:
USER apache
COPY docker-entrypoint.sh docker-entrypoint.sh
CMD ["/code/docker-entrypoint.sh"]

更新
根据@LiquidDeath的建议,我在RUN mkdir /code
语句后面的Dockerfile文件中添加了以下内容。
RUN mkdir -p /code/static
RUN mkdir -p /code/website/migrations
RUN echo $(ls -al)
RUN echo $(ls -al /code)
RUN chmod -R 777 /code/static/
RUN chmod -R 777 /code/website/migrations/
我检查了这些目录确实是通过运行带有--progress=plain
和--no-cache
标志的docker build命令创建的。
但是,一旦我实际运行docker-compose up
,仍然会遇到相同的PermissionError: [Errno 13] Permission denied

这可能是因为在装有Hyper-V的Mac和Windows中,容器是以root权限运行的。但是WSL2不允许你以超级用户身份运行。作为一种解决方案,您可以对目录/文件授予必要的权限(写入/执行)。
在您的docker文件中添加以下行
RUN chown -R apache /code/
COPY . /code/
RUN chmod -R 777 /code/static/
RUN chmod -R 777 /code/website/migrations/
777赋予所有者、用户和其他人完全权限,请根据您的要求更改此权限(请参阅linux中的权限)
