Summary

kube-prometheus-stack collects Kubernetes manifests, Grafana dashboards, and Prometheus rules combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with Prometheus using the Prometheus Operator.
Installs the kube-prometheus stack, a collection of Kubernetes manifests, Grafana dashboards, and Prometheus rules combined with documentation and scripts to provide easy to operate end-to-end Kubernetes cluster monitoring with Prometheus using the Prometheus Operator.

Dependencies

By default this chart installs additional, dependent charts:

03. 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.

ServiceMonitor

ServiceMonitor란 CRD(CustomResourceDefinition) 방식으로 Operator (코어OS 최초 시작)를 이용하여 Metric을 관리하는 방법 입니다.
Metric 추가 작업 시 prometheus.yml 파일에 manual하게 추가하는 것이 아니고 별도의 Kubernetes Object Servicemonitor (마치 configmap, deployment 처럼)를 이용합니다.
