deployment

Quick Start

  1. Create a working directory named after the service.
  2. Copy the compose file and generated `.env` into that directory.
  3. Review the variables and replace placeholders with real values.
  4. Run `docker compose up -d`.
mkdir grafana-prometheus-loki-node-exporter-stack
cd grafana-prometheus-loki-node-exporter-stack
# create docker-compose.yml
# create .env
docker compose up -d
