Instructions to build and run htlc-watchtower natively

git clone https://github.com/hypercore-one/htlc-watchtower.git
cd htlc-watchtower
dart pub get
dart run build_runner build --delete-conflicting-outputs
mkdir build
dart compile exe src/main.dart -o build/htlc-watchtower
cp example.config.json build/config.json

Setup htlc-watchtower as a service

sudo nano /etc/systemd/system/htlc-watchtower.service

Paste the following content into the terminal. Make sure the ExecStart= path is correct.

[Unit]
Description=HTLC-Watchtower Service
After=network.target

[Service]
User=root
Group=root
ExecStart=/home/$USER/htlc-watchtower/build/htlc-watchtower
ExecStop=/usr/bin/pkill -9 htlc-watchtower
Restart=on-failure
TimeoutStopSec=10s
TimeoutStartSec=10s
StandardOutput=syslog
StandardError=syslog
SyslogIdentifier=htlc-watchtower

[Install]
WantedBy=multi-user.target

Activate and start the htlc-watchtower service

systemctl daemon-reload
sudo systemctl enable htlc-watchtower
sudo systemctl start htlc-watchtower

Once the service is running check the status and note the ZTS address that requires fused QSR. Fuse 120 QSR to that address. Once fused the service will start working as expected.

 systemctl status htlc-watchtower

Instructions to build a docker image and run it as a container

Clone the repo and move into that folder

git clone https://github.com/hypercore-one/htlc-watchtower.git
cd htlc-watchtower

Create a config file from the template

cp example.config.yaml config.yaml

Ensure the url of the ZNN node in the config.yaml is accurate. Change the following URL if necessary.

node_url_ws: 'ws://127.0.0.1:35998'

Build an image and create a container to run the watchtower as a service

docker compose up -d

Check the ZTS address of the watchtower

docker compose logs --follow

Note the ZTS address and fuse 120 QSR to that address. Once the QSR is fused the watchtower will see the change and become live.
