04. Install Chart of kube-prometheus-stack

  • Info

    Operator는 특정 애플리케이션 컨트롤러 인 Kubernetes API를 확장하기 위해 회사에서 개발 한  CoreOS에 의해 생성됩니다 . 

    데이터베이스, 캐싱 및 모니터링 시스템과 같은 복잡한 상태 저장 애플리케이션을 생성, 구성 및 관리하는 데 사용됩니다. 

    Operator는 Kubernetes의 리소스 및 컨트롤러 개념을 기반으로하지만 일부 애플리케이션 별 전문 지식도 포함합니다.

    예를 들어 데이터베이스 운영자를 생성하려면 생성 된 데이터베이스의 다양한 운영 및 유지 관리 방법에 매우 익숙해야합니다. 

    Operator를 만드는 열쇠는 CRD (custom resources)의 디자인입니다.
