VitrualBox, Ubuntu, Docker, Nginx, 13: Permission denied

General
1

Hello!

  1. I installed Ubuntu 22 in Windows via VirtualBox
  2. I installed Docker in Ubuntu
  3. I shared a folder from Windows to Ubuntu via the path (/home/das/work)
  4. I created a small project in Windows to run via Docker

docker-compose.yml

services:
  nginx:
    container_name: nginx
    build: ./docker/nginx
    volumes:
      - ./:/work/www
      - ./docker/_data/nginx:/var/log/nginx
    ports:
      - "80:80"

/docker/nginx/Dockerfile

FROM nginx:1.18

ADD default.conf /etc/nginx/conf.d/default.conf

WORKDIR /work/www

RUN groupadd --gid 999 vboxsf

RUN usermod -aG vboxsf root

RUN chown -R root:vboxsf .

USER root

/docker/nginx/default.conf

server {
    index index.html;
    server_name demo;
    listen 80;
    access_log /var/log/nginx/access.log;
    error_log /var/log/nginx/error.log;
    root /work/www/public;
}

/public/index.html

<h1>Test</h1>

When I run docker I get the following error:
2025/03/17 06:45:51 [crit] 28#28: *2 stat() “/work/www/public/index.html” failed (13: Permission denied), client: 172.18.0.1, server: demo, request: “GET /index.html HTTP/1.1”, host: “demo”

How did you check if the file is readable and it is indeed whete you expect it?
