File Permission Error Using WebDAV Docker Mounted Volumes

Here is a step-by-step guide to help you set up a WebDAV server using Docker and provide user access to store data.

1. Install Docker on your system: Follow the official Docker installation guide for your operating system: https://docs.docker.com/get-docker/

2. Pull the WebDAV server image: Use the following command to pull the WebDAV server image from Docker Hub:

   docker pull nextcloud:latest
   

3. Run the WebDAV server container: Use the following command to run the WebDAV server container, replacing <data-directory> with the desired directory path for your data:

   docker run -d -p 80:80 -p 443:443 -v <data-directory>:/var/www/html nextcloud
   

4. Configure Nginx to proxy requests to the WebDAV server: Install Nginx on your system if you haven't already:

   sudo apt-get install nginx
   

   Create a new Nginx configuration file at /etc/nginx/sites-available/webdav:

   server {
       listen 80;
       server_name your_domain_or_IP;
   
       location / {
           proxy_pass http://localhost:80;
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       }
   }
   

   Enable the new configuration file and disable the default Nginx configuration:

   sudo ln -s /etc/nginx/sites-available/webdav /etc/nginx/sites-enabled/
   sudo systemctl reload nginx
   

5. Set up a user for WebDAV access: Add a new user and group for WebDAV access:

   sudo useradd -r webdav
   sudo groupadd webdav
   

   Change the ownership of the data directory to the new user and group:

   sudo chown -R webdav:webdav <data-directory>
   

6. Modify the Nextcloud configuration to use the new user and group: Access the WebDAV server container using the following command:

   docker exec -it <container-id> php /var/www/html/occ config:system:trust_host_verification false
   docker exec -it <container-id> php /var/www/html/occ config:system:verify_peer false
   docker exec -it <container-id> php /var/www/html/occ config:app:set --setting=overwrite_local_config --value=true
   docker exec -it <container-id> php /var/www/html/occ config:system:set trusted_domains --value="your_domain_or_IP"
   docker exec -it <container-id> php /var/www/html/occ config:system:set file_scan_chunk_size --value=10485760
   docker exec -it <container-id> php /var/www/html/occ user:create webdav --password=<password> [email protected] --name=WebDAV --uid=33 --gid=33
   docker exec -it <container-id> php /var/www/html/occ db:user:setadmin webdav
   

   Replace <container-id> with the ID of your WebDAV server container and <password> with a secure password for the WebDAV user.

7. Test the WebDAV server: Access your WebDAV server using a WebDAV client, such as Cyberduck, and use the webdav user and password you created.
