Using Systemd to Auto Start the Docker Container

Here's the quick start guide for setting up a systemd service that will listen on the defualt ports and start at boot time. It will also attempt to pull down image updates each time the service starts and automatically restart after 10 seconds if the process exits. This Docker container preserves no state across starts.

cd /etc/systemd/system
sudo curl -O
sudo systemctl daemon-reload
sudo systemctl enable --now docker-syncthing-relay.service
sudo systemctl status docker-syncthing-relay.service
Docker Pull Command
