name: Deploy (dev)

# dev 브랜치 push 시 dev 서버에 자동 배포:
#   서버에서 소스 pull → docker compose 로 dev-api 재빌드/기동
# (jar 빌드는 서버의 Dockerfile 이 수행 — CI 러너는 SSH 트리거만)
#
# 저장소 Settings > Actions > Secrets 에 등록:
#   DEPLOY_HOST     배포 서버 호스트/IP (예: 115.68.231.167)
#   DEPLOY_USER     SSH 계정 (docker 실행 권한 필요 — docker 그룹 또는 sudo)
#   DEPLOY_SSH_KEY  SSH 개인키 (PEM 전체)
#   DEPLOY_PATH     서버의 소스 경로 (예: /opt/dognation_BT) — git 체크아웃 위치
#   COMPOSE_FILE    docker-compose.yml 전체 경로 (선택, 기본 $DEPLOY_PATH/docker-compose.yml)
#   DEPLOY_PORT     SSH 포트 (선택, 기본 22)
