# 02 - Deployment

OxiCloud is deployed as a containerized application with PostgreSQL.

---

## Docker Setup

### Quick Start

1. **Copy the example environment file and customize it:**
   ```bash
   cp example.env .env
   # Edit .env with your settings
   ```

2. **Start the services:**
   ```bash
   docker compose up -d
   ```

3. **Access OxiCloud:**
   Open `http://localhost:8086` in your browser.

### Docker Compose

```yaml
# docker-compose.yml
services:
  postgres:
    image: postgres:17.4-alpine
    environment:
      POSTGRES_DB: oxicloud
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
    volumes:
      - pg_data:/var/lib/postgresql/data
      - ./db/schema.sql:/docker-entrypoint-initdb.d/schema.sql
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5

  oxicloud:
    image: oxicloud:latest
    ports:
      - "8086:8086"
    env_file:
      - .env
    volumes:
      - storage_data:/app/storage
    depends_on:
      postgres:
        condition: service_healthy

volumes:
  pg_data:
  storage_data:
```

### Dockerfile

3-stage Alpine-based build:
1. **Cacher** -- pre-builds dependency layer
2. **Builder** -- compiles OxiCloud (`rust:1.93.0-alpine3.23`)
3. **Runtime** -- minimal Alpine image (`alpine:3.23.3`) with `libgcc`, `ca-certificates`, `libpq`, `tzdata`, `su-exec`

Non-root user: `oxicloud` (UID/GID 1001). Exposed port: `8086`. Entrypoint: `entrypoint.sh` (chown storage + drop privileges via `su-exec`).

# Kubernetes Setup

## 01 - Dependencies
- K8S Cluster
- Default StorageClass
- Ingress Controller
- Helm

## 02 - Deployment
Change the `charts/oxicloud/values.yaml` to match your setup.

To install the Chart run:
```bash
helm upgrade --install oxicloud charts/oxicloud -f charts/oxicloud/values.yaml
```

## 03 - Verification

To verify your deployment run:
```bash
kubectl get pods -n oxicloud
kubectl logs statefulset/oxicloud -n oxicloud
```

If you have collabora enabled you want to check the logs:
```bash
kubectl logs statefulset/oxicloud -n oxicloud | grep "WOPI discovery loaded"
```
