[Kubernets][Rancher] Pod Metrics 보기

 

Rancher on Kubernetes (쿠버네티스 클러스터에 Rancher 설치)

 

Rancher on Kubernetes - 2 (Existing cluster import)

이전에 kubernetes에 Rancher 설치 및 연동 이후 Rancher에서 Pod Metrics 를 볼수 있도록 설정 해보자.

Rancher에서 Workload들의 Metrics을 보기 위해서는 kube-prometheus 설치가 필요하다. 설치는 Rancher 페이지에서 간단하게 설치가 가능하니 아래와 같이 따라하면 손쉽게 설치가 가능하다.

먼저 구성해놓은 Rancher로 접속하여 설정 후 Metrics 셋업이 필요한 Project로 접속한다.

이후 Cluster Tools 버튼을 클릭.

이후 여러 Cluster tools 중에 Monitoring 을 클릭한다.

설치 될 버전을 확인할 수 있으며 특정 namespace를 지정해서 설치도 가능하다.

Next 버튼을 누르면 Cluster type을 선택할 수 있다. On-premise 환경에 구성이 되어있어 Other를 선택. 그리고 Prometheus, Alerting, Grafana 의 설정등을 변경 할 수 있다. 특별히 변경 할 것이 없다면 Install 버튼을 누르자.

아래와 같이 터미널이 자동적으로 팝업되고 helm 을 통해서 설치가 진행되며 완료될 때 까지 대기한다.
