Description

## Syncthing by cloudimg

Syncthing is the popular open source, continuous file synchronization program - it synchronizes files between two or more devices peer-to-peer over an encrypted, authenticated connection, with no central server. A privacy-respecting alternative to hosted file sync, run here as an always-on sync node you control. This Amazon Machine Image delivers Syncthing fully installed and configured, so a private sync node is running within minutes of launch. The current release available is Syncthing 2.1.

## Application Stack

The Syncthing GUI and REST API - served by a single Go binary - run behind nginx as a reverse proxy; the sync protocol listens on port 22000. The GUI binds to the loopback interface.

## Secure First Boot

The GUI requires a username and password and the REST API requires an API key. On the first boot of every instance a one shot service regenerates the device certificate (a fresh Device ID), the API key and the administrator GUI password - all unique to that instance - and writes the login to a root only file. No shared or default credentials or device identity ship in the image.

## Ready To Use

Sign in to the GUI, add a folder to share and the Device IDs of the devices you want to sync with, and Syncthing keeps them in sync automatically. Install the Syncthing app on your other machines and pair them with this node.
