Installation

Warden is distributed as a Docker image and a Helm chart. It runs as a single binary with no external dependencies.

Docker (Recommended)

Pull and run the Warden image:

docker run -d \
  -p 9090:9090 \
  -v warden_data:/data \
  ghcr.io/projecthelena/warden:latest

Warden is now running at http://localhost:9090.

Docker Compose

With SQLite (Default)

Create a docker-compose.yml:

services:
  warden:
    image: ghcr.io/projecthelena/warden:latest
    ports:
      - "9090:9090"
    volumes:
      - warden_data:/data

volumes:
  warden_data:

docker compose up -d

With PostgreSQL

For larger deployments or high-availability setups:

services:
  warden:
    image: ghcr.io/projecthelena/warden:latest
    ports:
      - "9090:9090"
    environment:
      - DB_URL=postgres://warden:warden@db:5432/warden?sslmode=disable
    depends_on:
      db:
        condition: service_healthy

  db:
    image: postgres:17
    environment:
      - POSTGRES_USER=warden
      - POSTGRES_PASSWORD=warden
      - POSTGRES_DB=warden
    volumes:
      - pg_data:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD", "pg_isready", "-U", "warden"]
      interval: 5s
      retries: 5

volumes:
  pg_data:

docker compose up -d

Kubernetes (Helm Chart)

Warden has an official Helm chart for Kubernetes deployments. The chart supports SQLite, internal PostgreSQL (auto-deployed StatefulSet), or external PostgreSQL.

Source: github.com/projecthelena/helm-charts

Add the Helm Repository

helm repo add projecthelena https://charts.projecthelena.com
helm repo update

Install with SQLite (Default)

helm install warden projecthelena/warden \
  --namespace warden \
  --create-namespace

This deploys Warden with SQLite and a 1Gi PersistentVolumeClaim for data persistence.

Install with PostgreSQL

helm install warden projecthelena/warden \
  --namespace warden \
  --create-namespace \
  --set database.type=postgres \
  --set database.postgres.enabled=true \
  --set database.postgres.auth.password=your-secure-password

This deploys Warden alongside an internal PostgreSQL StatefulSet with 5Gi of persistent storage.

Install with an External PostgreSQL

If you already have a PostgreSQL instance:

helm install warden projecthelena/warden \
  --namespace warden \
  --create-namespace \
  --set database.type=postgres \
  --set database.external.enabled=true \
  --set database.external.url="postgres://user:pass@your-db-host:5432/warden?sslmode=require"

Exposing Warden with Ingress

Standard Kubernetes Ingress:

ingress:
  enabled: true
  className: nginx
  annotations:
    cert-manager.io/cluster-issuer: letsencrypt
  hosts:
    - host: status.example.com
      paths:
        - path: /
          pathType: Prefix
  tls:
    - secretName: warden-tls
      hosts:
        - status.example.com

Traefik IngressRoute:

ingressRoute:
  enabled: true
  entryPoints:
    - websecure
  routes:
    - match: Host(`status.example.com`)
      kind: Rule
  tls:
    certResolver: letsencrypt

Example: ArgoCD with Traefik and PostgreSQL

Here’s a complete ArgoCD Application manifest deploying Warden on Kubernetes with Traefik and an internal PostgreSQL database:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: warden
  namespace: argocd
spec:
  project: default
  source:
    repoURL: https://charts.projecthelena.com
    chart: warden
    targetRevision: 0.2.4
    helm:
      values: |
        database:
          type: postgres
          postgres:
            enabled: true
            auth:
              username: warden
              password: ""   # auto-generated — see ignoreDifferences below
              database: warden
            persistence:
              enabled: true
              size: 10Gi
              accessMode: ReadWriteOnce
              storageClass: your-storage-class
        ingressRoute:
          enabled: true
          entryPoints:
            - websecure
          routes:
            - match: Host(`status.example.com`)
              kind: Rule
          tls:
            certResolver: letsencrypt
  ignoreDifferences:
    - kind: Secret
      name: warden-postgresql
      jsonPointers:
        - /data
  destination:
    server: https://kubernetes.default.svc
    namespace: warden
  syncPolicy:
    automated:
      prune: true
      selfHeal: true
    syncOptions:
      - CreateNamespace=true
      - ServerSideApply=true
      - RespectIgnoreDifferences=true

Note

When using the auto-generated PostgreSQL password, the ignoreDifferences and RespectIgnoreDifferences settings are required. Without them, ArgoCD would overwrite the generated password on every sync.

Build from Source

Requirements: Go 1.25+ and Node.js 22+

git clone https://github.com/projecthelena/warden.git
cd warden
make build
./bin/warden

This builds the React frontend, embeds it into the Go binary, and outputs a single executable at bin/warden.

Environment Variables

Variable	Default	Description
LISTEN_ADDR	:9090	Address and port to listen on
DB_PATH	/data/warden.db	SQLite database file path
DB_URL	—	PostgreSQL connection string (auto-switches from SQLite)
COOKIE_SECURE	false	Set to true when running behind HTTPS
TRUST_PROXY	false	Set to true when behind a reverse proxy for correct IP-based rate limiting

Caution

COOKIE_SECURE should be set to true in production when serving over HTTPS. This prevents session cookies from being sent over unencrypted connections.

Caution

Only enable TRUST_PROXY if Warden is behind a trusted reverse proxy (e.g., Nginx, Caddy, Traefik, Cloudflare). Enabling it when directly exposed to the internet allows IP spoofing.

Database Options

Feature	SQLite (Default)	PostgreSQL
Setup	Zero configuration	Requires running PostgreSQL
Best for	Single instance, low-to-medium traffic	High availability, large-scale
Backups	Copy the database file	pg_dump or existing pipeline
Performance	Great for most workloads	Better under heavy concurrent writes

SQLite is the default and requires no setup. The database file is created automatically at the path specified by DB_PATH.

To use PostgreSQL, set the DB_URL environment variable. Warden auto-detects the database type from the connection string prefix.

Database Migrations

Migrations run automatically on startup. Warden ships with embedded migration files for both SQLite and PostgreSQL — no manual migration steps required.

Verifying the Installation

After starting Warden, open http://localhost:9090 in your browser (or your Ingress hostname for Kubernetes). You should see the setup page where you’ll create your first admin account.

You can also check the health endpoint:

curl http://localhost:9090/healthz
