Fixing File Permissions for Webtop on Synology: A Step-by-Step Guide

Introduction:

Webtop is a Docker container developed by LinuxServer.io that provides a desktop environment accessible via a web browser. It allows users to interact with their server in a graphical interface, offering a convenient way to manage files, run applications, and perform various tasks without needing to use command-line tools.

The Problem:

While running the Webtop container on Synology, you may encounter a situation where a Synology Shared directory, accessible only by administrators, is mounted to the container. Inside the container, the default user 'abc' cannot access this mounted volume. This issue persists even when you try to add the 'abc' user to the root user group. By default, the 'abc' user is in the users group.

The Solution:

After some exploration and troubleshooting, I discovered a workaround that resolved the issue. The solution involved adding the users group to the shared directory in Synology's File Station. Here's how you can do it:

Step-by-Step Guide:

1. Open Synology's DiskStation Manager (DSM) on your web browser.
2. Navigate to 'File Station' from the main menu.
3. Locate the shared directory that is mounted to the Webtop container.
4. Right-click on the shared directory and select 'Properties'.
5. In the Properties window, navigate to the 'Permission' tab.
6. Here, you will see a list of groups and users along with their respective permissions. Click on 'Create' to add a new permission setting.
7. In the 'Name' field, type 'users' to add the users group.
8. Set the permissions for the 'users' group as needed. At the very least, you should grant 'Read/Write' access.
9. Click 'OK' to save the changes.

By granting the 'users' group access to the shared directory, the 'abc' user inside the Webtop container should now be able to access the mounted volume.

Conclusion:

File permissions can often be a stumbling block when working with containers and shared directories. However, with a little bit of knowledge and some troubleshooting, you can effectively manage these permissions to suit your needs. In this case, the solution was to adjust the permissions of the shared directory in Synology's File Station, allowing the 'abc' user to access the mounted volume. Remember, understanding and managing file permissions is crucial to maintaining a secure and efficient system.
