Introduction to Gradio Share Server (FRP)

The Gradio Share Server, an adaptation of the Fast Reverse Proxy (FRP) project, is crafted to operate within Gradio's Share Server framework. This setup focuses primarily on facilitating the sharing of Gradio app links via customizable URLs, thereby enhancing accessibility and customizability for users who wish to share their work with others over the internet.

Background

Gradio, a popular framework for creating machine learning demos, allows users to generate shareable links for their apps. When the user creates a Gradio application and executes it with the share=True parameter, the application becomes accessible on the internet through a special link that typically looks like this: https://07ff8706ab.gradio.live. However, this accessibility is infused with some time constraints—limited to 72 hours.

The enhancement in accessibility is achieved using FRP, which stands as the medium to connect a local server (where the Gradio app is running) to the broader internet. FRP operates with two main components:

• FRP Client: This is downloaded to the user's local machine, enabling the Gradio app to get exposed to the internet.
• FRP Server: Hosted on Gradio's platforms or can be set up on a user-defined server to allow even more customizations.

This connection allows external users to reach the localized Gradio server via the public URL generated by the FRP Server.

Benefits of Hosting Your Own Share Server

Opting to run a personal share server has several advantages:

• Custom Domain Usage: Instead of the default Gradio domain, users can leverage their domains for the links.
• Extended Link Validity: By managing your server, the restrictive 72-hour link expiration can be bypassed.
• Enhanced Security: Hosting on a virtual private cloud ensures data privacy, satisfying stringent security requirements.

Transitioning to a personal server involves a change in how the Gradio application is launched. The new server's address is simply passed as the share_server_address parameter during the launch.

Steps to Set Up Your Share Server

Prerequisites:

• A Linux-based server with at least 2 GB RAM and 8 GB disk space, internet connectivity, and SSH access. A static IP and registered domain are crucial for the setup.
• A wildcard DNS setup to redirect all subdomains to this server is necessary.

Installation Process

1. Install Docker: Ensure Docker v. 20.10 or later is set up on the server using a sequence of commands available for Ubuntu distributions.

2. Clone the Repository: Clone the FRP repository from GitHub and navigate to the project directory.

3. Configuration File Editing: Modify the scripts/frps.ini file by setting the subdomain_host to reflect your custom domain and make any necessary adjustments to ports or page settings.

4. Launching Docker Container: Build and run the FRP Server Docker container, which requires root privileges in some environments.

5. Network Traffic Setup: Configure security and firewall settings to allow TCP and HTTP traffic on appropriate ports, assuring connectivity to the Share Server.

Conclusion

Once these steps are complete, your personalized Share Server is operational, capable of customizing app links to suit specific needs and enhancing security protocols. Use the server by implementing its address in the share_server_address parameter whenever launching a Gradio app. For HTTPS security, additional protocol configurations may be needed. This setup provides users with comprehensive control over their shared Gradio applications.
