+# crossword
+
+러시아 문학 가로세로 낱말풀이 — 정적 단일 페이지 사이트.
+
+- 공개 주소: https://crossword.plpark.ectech.co.kr
+- 내부 주소: http://192.168.0.216:31380 (NodePort)
+
+## 구성
+
+| 경로 | 설명 |
+|---|---|
+| `site/index.html` | 게임 본체 (원본: `프로젝트/02_crossword/russian-lit-crossword.html`) |
+| `nginx/default.conf` | nginx 설정 (8080 리슨, `/healthz` 헬스체크) |
+| `Dockerfile` | nginx:1.27-alpine 정적 서빙 이미지 |
+| `k8s/deployment.yaml` | Deployment + NodePort Service (31380) |
+| `Jenkinsfile` | Checkout → 이미지 빌드/푸시 → kubectl apply |
+
+Spring Boot 등 런타임은 없음. HTML/CSS/JS 만으로 동작하는 완전 정적 페이지라
+nginx 로 파일만 내려주면 끝.
+
+## 배포
+
+Jenkins 잡(`crossword`)을 돌리면 아래가 순서대로 진행된다.
+
+1. gitea `plpark/crossword` main 브랜치 체크아웃
+2. `gitea.plpark.ectech.co.kr/plpark/crossword:<BUILD_NUMBER>` 빌드 & 푸시
+3. `plpark-int-ns` 네임스페이스에 apply, rollout 대기
+
+Jenkins credentials 는 기존 loggen/pilot1 과 동일하게
+`gitea-registry`(usernamePassword), `rancher-kubeconfig`(file) 를 사용한다.
+
+## 프록시 (NPM)
+
+`https://npm.ectech.co.kr` 에서 Proxy Host 추가:
+
+- Domain Names: `crossword.plpark.ectech.co.kr`
+- Scheme: `http`
+- Forward Hostname / IP: `192.168.0.216`
+- Forward Port: `31380`
+- Block Common Exploits / Websockets Support: ON
+- SSL: Let's Encrypt 발급 + Force SSL + HTTP/2
+
+## 콘텐츠 수정
+
+`site/index.html` 만 고치고 커밋 → Jenkins 빌드. 그 외 변경 필요 없음.
