我正在使用 docker 容器来执行位于我的主机上的 python 脚本。该脚本应在目标位置创建一个新目录。

当目标位置位于 $HOME 或 $HOME/* 下时，一切正常。但是，当我想在 /media/my_name/external_drive 创建一个目录时，终端说 PermissionError： [errno 13] 权限被拒绝： '/media/my_name'

这是我运行的代码

sudo docker-compose run --rm --user=“$（id -u）：$（id -g）” main process_all.py

这是docker-compose.yml：

version: '2.3'
services:
  main:
    build: .
    volumes:
      - .:/app
      - /etc/localtime:/etc/localtime:ro
    environment:
      - PYTHONIOENCODING=utf_8
    init: true
    network_mode: host
