# 참고:
# 1. KIND 클러스터 자체는 docker-compose로 직접 제어되지 않습니다
# 2. 이 파일은 KIND 클러스터 관리를 위한 헬퍼 컨테이너들을 제공합니다
# 3. 실제 클러스터 생성/삭제는 kind CLI를 사용해야 합니다
#
# KIND 클러스터 라이프사이클:
#   생성: kind create cluster --config k8s/kind-dev-cluster.yaml
#   삭제: kind delete cluster --name site11-dev
#   목록: kind get clusters
#
# docker-compose 명령어:
#   헬퍼 시작: docker-compose -f docker-compose.kubernetes.yml up -d
#   헬퍼 중지: docker-compose -f docker-compose.kubernetes.yml down
#   로그 확인: docker-compose -f docker-compose.kubernetes.yml logs -f kind-monitor
