Run from source

Build and run Lyna without Docker. You need Java 25, Node.js 24 and Git.

The backend

Build it:

git clone https://github.com/rainbowdashlabs/lyna.git
cd lyna
./gradlew installDist

That lays out a runnable copy in build/install/lyna/, with the start script bin/lyna. Copy that directory to where Lyna should live.

Lyna reads config/ from its working directory, so start it from the directory that holds config/:

cd /opt/lyna
export JAVA_OPTS="-Dlog4j.configurationFile=config/log4j2.xml"
./bin/lyna

JAVA_OPTS tells Log4j where your logging file is. Give the secrets as environment variables, see secrets. The backend listens on port 8888 on every address; change api.host and api.port if that doesn't suit you.

The frontend

cd frontend
npm ci
NODE_OPTIONS="--max-old-space-size=8192" npm run build

The build ends up in frontend/.output/. Start it with the backend's address:

NUXT_BACKEND_URL=http://127.0.0.1:8888 NITRO_PORT=3000 node .output/server/index.mjs

Then put a reverse proxy in front of port 3000.

Keeping it running

Run both as services of your system, for example with systemd, and restart them after an upgrade. To upgrade, pull the new code, build both again, and restart. See upgrading.
