  Syncthing in Docker is a popular way to keep your file synchronization environment isolated and easily deployable. Here’s a quick guide on how to get started:

1. Pull the Official Syncthing Docker Image

You can pull the latest official image from Docker Hub with:

bash

docker pull syncthing/syncthing:latest

2. Prepare Your Host Directories

Create directories on your host machine to persist your Syncthing configuration and data:

bash

mkdir -p ~/syncthing/config
mkdir -p ~/syncthing/data

3. Run the Syncthing Container

Here’s a sample command to start the Syncthing container:

bash

docker run -d \
  --name=syncthing \
  -e PUID=1000 \            # (Optional) set user id if needed
  -e PGID=1000 \            # (Optional) set group id if needed
  -e TZ=America/New_York \  # (Optional) set your timezone
  -p 8384:8384 \            # Web GUI port
  -p 22000:22000 \          # Sync protocol port
  -p 21027:21027/udp \       # Local discovery port (UDP)
  -v ~/syncthing/config:/var/syncthing/config \
  -v ~/syncthing/data:/var/syncthing/data \
  syncthing/syncthing:latest

• Ports Explained:
  • 8384: Access Syncthing’s web GUI.
  • 22000: The port Syncthing uses for syncing.
  • 21027 (UDP): Used for local discovery of other Syncthing devices.
• Volumes Explained:
  • Configuration (~/syncthing/config): Stores your Syncthing settings.
  • Data (~/syncthing/data): The directory where your synchronized files are stored.

4. Access the Web GUI

Once the container is running, you can access the Syncthing web interface by navigating to:

arduino

http://localhost:8384

From there, you can configure devices, folders, and other settings.

5. Additional Configuration

• User and Group IDs (PUID and PGID): If you're running on a system with specific user permissions, setting these environment variables ensures proper file permissions.
• Timezone (TZ): Adjust the timezone to match your local setting.

6. Managing the Container

• Stop the Container:

  bash
  
  docker stop syncthing
  

• Restart the Container:

  bash
  
  docker restart syncthing
  

• View Logs:

  bash
  docker logs syncthing
