Improve Discovery

Improve discovery of your node by publushing your node's IP address. Resolve IP address and set it int .env file for EXTERNAL_IP=:

curl https://ipinfo.io/ip # prints your IP address
nano .env

Monitoring

Enable monitoring by setting up your password to grafana and secure access. Set password in .env file for GRAFANA_PASSWORD=:

nano .env

Setup secure access:

cd grafana/etc
sudo openssl genrsa -out grafana.key 2048
sudo openssl req -new -key grafana.key -out grafana.csr
sudo openssl x509 -req -days 365 -in grafana.csr -signkey grafana.key -out grafana.crt
sudo chmod 400 grafana.key grafana.crt

Start

sudo docker compose up -d

to stop run:

sudo docker compose down

Monitor

Replace IP address with your node's IP and navigate to https://IP:46321. Select advance settings and proceed to an unsafe connection if prompted by a web browser. It may take some time to fully sync the chain, but some metrics should be populated within few minutes.
