Installation

Install on a Linux LAN Server

Run QuoteNode on an internal Linux server for an office or VPN-only team.

Install on a Linux LAN Server

Use this path when QuoteNode should run on an internal Linux server, VM, or mini-PC reachable by the office network or VPN.

When to use it

Several internal users need a stable shared instance.
Public customer access is not required.
You prefer a Linux host over Docker Desktop.

What will not work

Public offer links work only for users who can reach the server address.
Email delivery can work with SMTP, but recipients outside the LAN cannot open internal links.
Self-signed internal HTTPS may show browser warnings unless your organization trusts the certificate authority.

Prerequisites

Ubuntu, Debian, or another maintained Linux distribution.
Docker Engine 24.0+ and Docker Compose v2.
A static IP or DHCP reservation for the server.
SSH access for operators.
At least 2 GB RAM and 10 GB free disk space.
Backup storage outside the main Docker volume.
A 64-bit x86 host (linux/amd64). ARM devices, including ARM-based NAS models, are not supported.

Verify your setup:

docker --version        # Should show 24.0+
docker compose version  # Should show v2.x

Step 1 — Create a project directory

mkdir quotenode && cd quotenode
curl -fsSLO https://quotenode.dev/releases/v0.9.8-alpha/quotenode-deploy-v0.9.8-alpha.tar.gz
tar -xzf quotenode-deploy-v0.9.8-alpha.tar.gz --strip-components=1

This downloads the deployment package of release v0.9.8-alpha: docker-compose.yml with every image pinned by digest, env.example, release.json (the release identity) and operator/ (backup and restore tools).

Known issue in v0.9.5-alpha: its env.example contains an active sample line, BACKUP_RCLONE_REMOTE=s3:mybucket/backups, that makes every backup fail. The settings in this guide do not contain it; if you copy settings from env.example, leave that line out (details).

Step 2 — Create the configuration file

Create a file named .env. Replace 192.168.1.20 with your server’s actual LAN IP or internal DNS name (e.g. crm.internal). The secret values below are filled with fresh random values in your browser on each page load — use the ↻ New secrets button on the block to regenerate them, then copy the result. (Prefer to generate them yourself? See Deployment environment variables.)

# Database
DB_URL=jdbc:postgresql://postgres:5432/quotenode
DB_USERNAME=quotenode
DB_PASSWORD=change-me-to-something-random-32-chars
DB_NAME=quotenode

# ============================================================
# SECURITY SECRETS — UNIQUE to this installation.
# SAVE THIS FILE and keep a secure backup.
# ============================================================
DB_ENCRYPTION_KEY=0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef
TIMING_TOKEN_SECRET=change-me-timing-secret-min-32-chars
PUBLIC_LINK_PASSWORD_SESSION_SECRET=change-me-session-secret-min-32

# LAN URL — replace with your server IP or internal DNS name
CORS_ALLOWED_ORIGINS=http://192.168.1.20
DOMAIN=http://192.168.1.20

# Client IP is auto-detected behind internal proxies and CDNs (Cloudflare included) — leave empty.
# Set only for an unusual proxy whose transport peer is a PUBLIC address to trust (IP/CIDR or hostname).
SECURITY_TRUSTED_PROXIES=

# Application
LOG_LEVEL=INFO
SPRING_PROFILES_ACTIVE=prod

Behind your own reverse proxy that terminates HTTPS (here at 192.168.1.5), use the HTTPS origin, serve plain HTTP behind the proxy and trust only that proxy:

CORS_ALLOWED_ORIGINS=https://crm.internal.example
DOMAIN=:80
EDGE_TRUSTED_PROXIES=192.168.1.5

Save your .env file immediately. Store a copy outside this server. If you lose DB_ENCRYPTION_KEY, encrypted fields become permanently unreadable.

Step 3 — Review the Docker Compose file

The package’s docker-compose.yml runs release v0.9.8-alpha with every image pinned by digest. Do not edit it: all settings go into .env, and an upgrade replaces this file with the next release’s version. For reference:

x-json-file-logging: &json-file-logging
  driver: json-file
  options:
    max-size: "${DOCKER_LOG_MAX_SIZE:-10m}"
    max-file: "${DOCKER_LOG_MAX_FILE:-5}"

DOMAIN selects how the caddy entry point serves QuoteNode: a public host name (crm.example.com) gets an automatic HTTPS certificate; http://<address> or :80 serves plain HTTP on a trusted network. If ports 80/443 are already in use, set HTTP_PORT / HTTPS_PORT in .env. Behind your own reverse proxy, set DOMAIN=:80 and list the proxy address in EDGE_TRUSTED_PROXIES.

Step 4 — Start QuoteNode

docker compose up -d

Docker will download the container images on the first run. Watch the startup:

docker compose logs -f backend

Wait until you see Started QuoteNodeApplication.

Step 5 — Open QuoteNode

Navigate to http://192.168.1.20 (or your server address) from any device on the LAN.

Default login credentials:

Field	Value
Email	`[email protected]`
Password	`Admin123!`

Change the default password immediately after logging in.

What is running?

Container	What it does	RAM usage
`postgres`	Stores all your data	~256 MB
`backend`	Java API server, business logic	~512 MB – 1.5 GB
`gotenberg`	Converts HTML to PDF (Chromium-based)	~200 MB
`frontend`	Serves the web interface	~20 MB
`backup-worker`	Runs scheduled backups (same image as the backend)	~300 MB
`caddy`	Entry point: HTTPS certificates, routing, security headers	~20 MB

Total: approximately 1.5 – 2.5 GB RAM.

Common commands

# Check service status
docker compose ps

# View logs
docker compose logs -f backend

# Stop QuoteNode
docker compose down

# Upgrade: replace docker-compose.yml with the next release package (see the upgrade guide)

Keeping your secrets safe

Secret	What it protects	If lost
`DB_PASSWORD`	Database access	Recoverable — reset via PostgreSQL admin tools
`DB_ENCRYPTION_KEY`	MFA codes, SMTP password, FX API key, PII fields	Permanently unreadable
`TIMING_TOKEN_SECRET`	Anti-timing-attack tokens	Regenerate — users re-authenticate
`PUBLIC_LINK_PASSWORD_SESSION_SECRET`	Public link sessions	Regenerate — active sessions expire

The critical secret is DB_ENCRYPTION_KEY. Store .env backups outside this server. See Installation troubleshooting for recovery steps.

Recommended next steps

Configure scheduled backups and test a restore.
Test PDF generation after first deployment.
Use Ubuntu public server or Coolify when public offer links must work for customers.
