Docker: 使用 --volume 绑定挂载进行文件权限

我正在遵循这篇文章的指导：https://denibertovic.com/posts/handling-permissions-with-docker-volumes/，在容器中设置一个--volume绑定挂载，并创建一个与主机用户相同UID的客户容器用户 - 理论上，我的容器用户应该能够访问该挂载点。但对我来说并没有起作用，我正在寻找一些下一步尝试的指导。\n更多背景细节：\n我的Dockerfile从一个alpine基础开始，然后添加python开发包。根据denibertovic的指导，它复制了一个entrypoint.sh脚本。然后跳转到entrpoint.sh脚本。\n

FROM alpine
RUN apk update
RUN apk add bash
RUN apk add python3
RUN apk add python3-dev
RUN apk add su-exec
COPY entrypoint.sh /usr/local/bin/entrypoint.sh
RUN chmod +x /usr/local/bin/entrypoint.sh
ENTRYPOINT ["/usr/local/bin/entrypoint.sh"]

\nentrpoint.sh脚本使用作为环境变量传递的UID向容器添加一个用户。\n

#!/bin/bash
# 添加本地用户
# 使用LOCAL_USER_ID（如果在运行时传入）或者回退到默认值
USER_ID=${LOCAL_USER_ID:-9001}
echo "Starting with UID : $USER_ID"
adduser -s /bin/bash -u $USER_ID -H -D user
export HOME=/home/user
su-exec user "$@"

\n容器无问题地构建。\n然后我用以下命令行运行它：\n

sudo docker run -it -e LOCAL_USER_ID=`id -u` -v `realpath ../..`:/ws django-runtime /bin/bash

\n你会看到我传入了我的主机UID以映射到容器用户的UID，并且我要求从我的本地工作目录到容器中的/ws挂载点进行挂载。\n从容器内的bash shell中，我可以看到/ws的所有者是\'user\'的UID，与我的\'id\'相匹配。然而，当我尝试列出/ws的内容时，我遇到了权限被拒绝的错误，如下所示：\n

[dleclair@localhost runtime]$ sudo docker run -it -e LOCAL_USER_ID=`id -u` -v `realpath ../..`:/ws django-runtime /bin/bash
[sudo] password for dleclair:
