kubernetes 部署prometheus筆記 (三)

1.  部署 node-exporter.yaml:

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: node-exporter
  namespace: kube-system
spec:
  #updateStrategy:
  #  rollingUpdate:
  #    maxUnavailable: 1
  #  type: RollingUpdate
  selector:
    matchLabels:
      app: node-exporter
  template:
    metadata:
      labels:
        app: node-exporter
      name: node-exporter
    spec:
      #serviceAccountName: node-exporter
      securityContext:
        runAsNonRoot: true
        runAsUser: 65534
      hostNetwork: true
      hostPID: true
      containers:
      - image: quay.io/prometheus/node-exporter:v0.15.2
        args:
        - "--web.listen-address=127.0.0.1:9101"
        - "--path.procfs=/host/proc"
        - "--path.sysfs=/host/sys"
        name: node-exporter
        resources:
          requests:
            memory: 30Mi
            cpu: 100m
          limits:
            memory: 50Mi
            cpu: 200m
        volumeMounts:
        - name: proc
          readOnly:  true
          mountPath: /host/proc
        - name: sys
          readOnly: true
          mountPath: /host/sys
      - name: kube-rbac-proxy
        image: quay.io/brancz/kube-rbac-proxy:v0.2.0
        args:
        - "--secure-listen-address=:9100"
        - "--upstream=http://127.0.0.1:9101/"
        ports:
        - containerPort: 9100
          hostPort: 9100
          name: https
        resources:
          requests:
            memory: 20Mi
            cpu: 10m
          limits:
            memory: 40Mi
            cpu: 20m
      tolerations:
        - effect: NoSchedule
          operator: Exists
      volumes:
      - name: proc
        hostPath:
          path: /proc
      - name: sys
        hostPath:
          path: /sys

2. 部署kube-state-metric:

    git clone https://github.com/kubernetes/kube-state-metrics.git

    cd kube-state-metrics

    kubectl create -f kubernetes/
