상세 작업 내용

 

 

1. prometheus-operator-crd 설치

• Thanos 사용을 위한 prometheus-operator 설치

#chart : prometheus-operator-crds
git clone https://github.com/prometheus-community/helm-charts

경로 : helm-charts/charts/prometheus-operator-crds

helm install -f prometheus-operator-crds values.yaml ./

 

2. kube-prometheus-stack 설치

#chart: kube-prometheus-stack
git clone https://github.com/prometheus-community/helm-charts
경로 : helm-charts/charts/kube-prometheus-stack

 

• chart.yaml 에서 dependencies 수정

#Chart.yaml 에서 아래와 같이 dependencies 를 주석처리
#
dependencies:
  #  - name: crds
  #  version: "0.0.0"
  #  condition: crds.enabled
      #  - name: kube-state-metrics
      #version: "5.14.*"

      #  - name: grafana
      #version: "6.60.*"
      #repository: https://grafana.github.io/helm-charts
      #condition: grafana.enabled
      #- name: prometheus-windows-exporter
      #repository: https://prometheus-community.github.io/helm-charts
      #version: "0.1.*"

• 시크릿 생성

kubectl create secret generic objstore-secret \
  --from-file=objstore.yaml \
  --namespace default

• values.yaml 수정

사용하지않는 컴포넌트 미사용으로 설정
사용하는경우 개인적으로 수정해서 사용하면 됨

EX)
		#239 alertmanager false
		#900 grafana false
		#1866 kubestatemetrics false
        
        3442 thanos secret setting <아래 사진참고>

 

• helm install

helm install kube-prometheus-stack -f values.yaml ./
