This Docker Compose configuration sets up Pingvin Share with Tailscale as a sidecar container to securely share files over a private Tailscale network. By using Tailscale in a sidecar configuration, you can ensure your file-sharing instance is accessible only within your Tailscale network, providing enhanced security and privacy.

Pingvin Share is a simple, open-source file-sharing application designed to make sharing files quick, easy, and efficient. It supports drag-and-drop uploads, expiring links, and a user-friendly web interface. With this setup, Tailscale ensures that your Pingvin Share instance remains secure and private, limiting access to only authorized devices on your Tailscale network.

In this setup, the tailscale-pingvin service runs Tailscale, which manages secure networking for the Pingvin Share service. The pingvin-share service uses the Tailscale network stack via Docker's network_mode: service: configuration. This ensures that Pingvin Share’s web interface and file-sharing capabilities are only accessible through the Tailscale network (or locally, if preferred), providing an extra layer of security and privacy for your self-hosted file-sharing needs.
