# Deployment

## Node Agent

Run this on every Incus host:

```bash
cd /opt/incus-backup-ui/backend
cp .env.example .env
npm install
sudo npm start
```

Important `.env` values:

```env
HOST="0.0.0.0"
PORT=3000
API_TOKEN="long-random-token-at-least-32-characters"
HTTPS_ENABLED=true
TLS_CERT_FILE="/etc/incus-backup-agent/tls.crt"
TLS_KEY_FILE="/etc/incus-backup-agent/tls.key"
ALLOWED_MANAGEMENT_IPS="management-server-ip"
```

`API_TOKEN` is required and must be at least 32 characters long. If `ALLOWED_MANAGEMENT_IPS` is set, the agent only accepts requests from those comma-separated IP addresses.

For private networks such as NetBird, the agent can serve HTTPS directly with an internal CA. Create one CA and sign one certificate per agent. The certificate must contain the NetBird IP or internal DNS name as a SAN:

```bash
sudo install -d -m 700 /etc/incus-backup-agent
openssl genrsa -out agent-ca.key 4096
openssl req -x509 -new -nodes -key agent-ca.key -sha256 -days 3650 -out agent-ca.crt -subj "/CN=Incus Backup Agent CA"
openssl genrsa -out tls.key 4096
openssl req -new -key tls.key -out tls.csr -subj "/CN=incus-node-1"
printf "subjectAltName=IP:100.127.0.10,DNS:incus-node-1.netbird\n" > tls.ext
openssl x509 -req -in tls.csr -CA agent-ca.crt -CAkey agent-ca.key -CAcreateserial -out tls.crt -days 825 -sha256 -extfile tls.ext
sudo install -m 600 tls.key /etc/incus-backup-agent/tls.key
sudo install -m 644 tls.crt /etc/incus-backup-agent/tls.crt
```

Copy `agent-ca.crt` to the management server and set `AGENT_CA_FILE` there.

Install systemd service:

```bash
sudo cp deploy/systemd/incus-backup-agent.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now incus-backup-agent
sudo journalctl -u incus-backup-agent -f
```

## Management API

Run this on the management server:

```bash
cd /opt/incus-backup-ui/management
cp .env.example .env
npm install
npm start
```

Important `.env` values:

```env
PORT=3100
SESSION_SECRET="long-random-secret"
AUTH_USERNAME="admin"
AUTH_PASSWORD="initial-password"
DATABASE_PATH="./management.sqlite"
CORS_ORIGINS="https://backup.example.com"
SESSION_COOKIE_SECURE=true
ALLOW_INSECURE_AGENT_HTTP=false
AGENT_CA_FILE="/etc/incus-backup-management/agent-ca.crt"
```

`AUTH_PASSWORD` is required for the first start when the user database is empty. `CORS_ORIGINS` must list the frontend origins that are allowed to use cookie-authenticated API calls. Agent URLs must use `https://`; only set `ALLOW_INSECURE_AGENT_HTTP=true` for local development. `AGENT_CA_FILE` should point to the CA certificate that signed the internal agent certificates.

Reset an existing password:

```bash
npm run reset-password -- admin "new-password"
```

Install systemd service:

```bash
sudo useradd --system --home /opt/incus-backup-ui --shell /usr/sbin/nologin incus-backup
sudo chown -R incus-backup:incus-backup /opt/incus-backup-ui/management
sudo cp deploy/systemd/incus-backup-management.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now incus-backup-management
sudo journalctl -u incus-backup-management -f
```

## Frontend

Point the frontend at the management API:

```bash
cd /opt/incus-backup-ui/frontend
npm install
VITE_API_URL=http://management-server:3100/api npm run build
npm run preview -- --host 0.0.0.0
```

For production, put the frontend and management API behind HTTPS.
