[bug] unexpected 403 error caused by permission setting

[dqhl76]

Thanks for your excellent docker image!

I am trying to use this image to setup a webdav enviroment to test OpenDAL's webdav service.
apache/opendal#2873

However, I face some problems when I want to mount a volume for data like this:

version: '3.8'

services:
  webdav:
    image: dgraziotin/nginx-webdav-nononsense
    ...
     volumes:
      - webdav-data:/data
    ...
volumes:
  webdav-data:

You can check what we actually write this docker compose file in https://github.com/apache/incubator-opendal/pull/2873/files/111e694f7c036cfcc8e92649db9fce28206c8666

The webdav service gave us the 403 Forbidden error. Log: https://github.com/apache/incubator-opendal/actions/runs/5877080995/job/15936499613?pr=2873

Errors may be caused by incorrect permission settings. We try to add a Dockerfile and that solve this problem:

FROM dgraziotin/nginx-webdav-nononsense

RUN chown -R abc:abc /data

We seem need to create the dir and set the permission first before mark it as a volumn.

If you think we need to fix it. I am glad to give a PR.

Hi, thank you for reporting this and providing as many details as possible. This bug has been reported sporadically in the past, and I have been unable to replicate it. Some people have experienced it in certain environments but not in others. There is surely something odd related to permissions. I won't be able to look at this for the next 10 days or so. If you have time to investigate the source of this bug in the meantime, I would really appreciate it!

Todo for me: unscrew this, trigger the image build again.

This should now be fixed and integrated in the (currently building) 1.25.2.

I also opened #96 as a TODO for me to prevent this from happening again. Sorry for the inconvenience. In short, my Dockerfile is generated whenever a new release of nginx comes out (currently manually triggered). Changes to the Dockerfile in main are overwritten whenever an image gets built. Of course, I forgot about it 😥
