# Ubuntu 22.04 + Docker로 운영 배포 (prompt.ncue.net)

목표: `https://prompt.ncue.net` → Caddy(자동 HTTPS) → `web`(Next.js) → PostgreSQL(`ncue.net/all_prompt`)

## 1) 서버 사전 준비

### 1.1 DNS

- `prompt.ncue.net` A 레코드가 서버 공인 IP를 가리키도록 설정

### 1.2 방화벽

- TCP 80, 443 오픈

### 1.3 Docker 설치

```bash
sudo apt-get update
sudo apt-get install -y ca-certificates curl gnupg

sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo $VERSION_CODENAME) stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update
sudo apt-get install -y docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo systemctl enable --now docker
```

## 2) 배포

```bash
sudo mkdir -p /opt/all-prompt
sudo chown -R $USER:$USER /opt/all-prompt

cd /opt/all-prompt
git clone <YOUR_REPO_URL> .

cp .env.example .env
nano .env
```

`.env` 필수:

- `DATABASE_URL`: `postgresql://ncue:<PASSWORD>@ncue.net:5432/all_prompt?schema=public`
- `CADDY_EMAIL`: 인증서 발급용 이메일

실행:

```bash
docker compose up -d --build
docker compose ps
```

확인:

- `https://prompt.ncue.net/api/health`
- `https://prompt.ncue.net/entities`
- `https://prompt.ncue.net/prompts`

## 3) 초기 스키마/시드(필요할 때만 1회)

> 원격 DB에 테이블이 없다면 실행.

```bash
docker compose --profile init run --rm db_init
docker compose --profile init run --rm db_seed
```

## 4) 운영 팁

### 로그

```bash
docker compose logs -f --tail=200 web
docker compose logs -f --tail=200 caddy
```

### 업데이트

```bash
git pull
docker compose up -d --build
```

### 인증서/설정 데이터

- Caddy 데이터는 도커 볼륨(`caddy_data`, `caddy_config`)에 유지됨
