Docker Installation Issue: Failed Copy File using OpenWebUI

Docker is a popular and powerful containerization platform that enables developers and system administrators to package and deploy applications in a consistent and isolated manner. This article focuses on a common issue encountered while using OpenWebUI with an already installed Docker on an Ollama system.

Prerequisites

Before we delve into the main issue, it is essential to understand some key concepts. First, know what Docker is and its importance in modern software development. Second, familiarize yourself with OpenWebUI, the UI for managing and monitoring Docker containers. Lastly, ensure that Docker is properly installed on the Ollama system.

Issue: Failed Copy File using OpenWebUI

Upon trying to run the docker run command, the following error message appears:

The error message indicates that the Docker daemon failed to copy files from the source directory to a container due to a read-only file system. OpenWebUI requires write access to specific directories, but the issue occurs when OpenWebUI encounters a read-only file system.

Solution

To resolve this issue, users must modify the file system's permissions or remount it with write access. Here's a step-by-step procedure to solve the problem:

1. Identify the source directory path in the docker run command.
2. Check the file system permissions for that directory:

3. If the file system is read-only, remount it with write access:

Or, if necessary, remount the entire root file system:

5. Verify the file system's new permissions:

The file system should now have write permission, and attempting the docker run command again should resolve the issue.

Docker and OpenWebUI are valuable tools for developers and administrators, but encountering a read-only file system can cause issues when attempting to copy files. Remember that identifying the problem and understanding how to modify the file system permissions or remounting it with write access are crucial for resolving this issue.
