# Norish Helm Chart

A Helm chart for deploying [Norish](https://github.com/norishapp/norish), a recipe management and meal planning application, on Kubernetes.

## Introduction

This chart deploys Norish on a Kubernetes cluster. Norish requires an external PostgreSQL database, a Redis server, and includes a Chrome headless sidecar for recipe parsing. It supports multiple authentication methods including password auth, OIDC, GitHub OAuth, and Google OAuth.

Source code: https://github.com/rtomik/helm-charts/tree/main/charts/norish

## Prerequisites

- Kubernetes 1.19+
- Helm 3.0+
- **PostgreSQL database** (required)
- **Redis server** (required)
- PV provisioner support (if persistence is enabled)

## Installing the Chart

```bash
helm repo add rtomik https://rtomik.github.io/helm-charts
helm install norish rtomik/norish
```

## Uninstalling the Chart

```bash
helm uninstall norish
```

## Configuration Examples

### Minimal Installation (Password Authentication)

```yaml
database:
  host: "postgresql.default.svc.cluster.local"
  port: 5432
  name: norish
  username: norish
  password: "secure-password"

redis:
  host: "redis.default.svc.cluster.local"
  port: 6379
  database: 0

config:
  authUrl: "https://norish.example.com"
  masterKey:
    value: "<your-32-byte-base64-key>"  # Generate: openssl rand -base64 32

ingress:
  enabled: true
  hosts:
    - host: norish.example.com
      paths:
        - path: /
          pathType: Prefix
  tls:
    - hosts:
        - norish.example.com
```

### Production with Existing Secrets

```yaml
database:
  host: "postgresql.default.svc.cluster.local"
  existingSecret: "norish-db-secret"
  usernameKey: "username"
  passwordKey: "password"

redis:
  existingSecret: "norish-redis-secret"
  urlKey: "redis-url"

config:
  authUrl: "https://norish.example.com"
  masterKey:
    existingSecret: "norish-master-key"
    secretKey: "master-key"
```

Create the required secrets:

```bash
kubectl create secret generic norish-db-secret \
  --from-literal=username="norish" \
  --from-literal=password="secure-db-password"

kubectl create secret generic norish-redis-secret \
  --from-literal=redis-url="redis://username:password@redis.default.svc.cluster.local:6379/0"

kubectl create secret generic norish-master-key \
  --from-literal=master-key="$(openssl rand -base64 32)"
```

### OIDC Authentication

```yaml
config:
  auth:
    oidc:
      enabled: true
      name: "Authentik"
      issuer: "https://auth.example.com/application/o/norish/"
      clientId: "<your-client-id>"
      clientSecret: "<your-client-secret>"
  # Optional: allow password auth alongside OIDC
  passwordAuthEnabled: "true"
```

### GitHub OAuth

1. Create a GitHub OAuth App at https://github.com/settings/developers
2. Set Authorization callback URL to: `https://norish.example.com/api/auth/callback/github`

```yaml
config:
  auth:
    github:
      enabled: true
      clientId: "<your-github-client-id>"
      clientSecret: "<your-github-client-secret>"
```

### Google OAuth

1. Create OAuth credentials at https://console.cloud.google.com/apis/credentials
2. Set Authorized redirect URI to: `https://norish.example.com/api/auth/callback/google`

```yaml
config:
  auth:
    google:
      enabled: true
      clientId: "<your-google-client-id>"
      clientSecret: "<your-google-client-secret>"
```

## Upgrading

### From v0.13.x to v0.14.x

**Breaking change**: Redis is now required. Configure Redis before upgrading (see [Redis Configuration](#redis-configuration-required)).

### From v0.14.x to v0.15.x

No configuration changes required. Redis, PostgreSQL, and Chrome headless are already configured. Back up your database before upgrading as a precaution.

## Troubleshooting

- **Master Key Not Set**: Generate with `openssl rand -base64 32`
- **Login Failures**: Password auth is enabled by default when no OAuth/OIDC is configured. Verify callback URLs match your ingress hostname.
- **Database Connection Failed**: Verify host, credentials, and that the database exists.
- **Chrome Headless Issues**: Chrome requires `SYS_ADMIN` capability and 256Mi-512Mi memory. Check logs with `kubectl logs -l app.kubernetes.io/name=norish -c chrome-headless`
- **Recipe Parsing Failures**: Ensure Chrome is running. `CHROME_WS_ENDPOINT` is automatically configured by the chart.

```bash
kubectl get pods -l app.kubernetes.io/name=norish
kubectl logs -l app.kubernetes.io/name=norish
```
