k8s部署prometheus

部署pvc

修改nfs-deployment.yaml文件中的信息，然后应用YAML文件

cat > /opt/k8s/prometheus/prometheus-pvc.yaml <<EOF
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: prometheus-data-pvc
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: "nfs-storage"
  resources:
    requests:
      storage: 5Gi
EOF

kubectl apply -f prometheus-pvc.yaml 
kubectl get pvc

部署ConfigMap

上传文件prometheus.yml 、alert.mysql.rules.yml 、alert.node.rules.yml到/opt/k8s/prometheus/file/下

kubectl create configmap prometheus-config \
  --from-file=prometheus.yml=/opt/k8s/prometheus/file/prometheus.yml \
  --from-file=alert.mysql.rules.yml=/opt/k8s/prometheus/file/alert.mysql.rules.yml \
  --from-file=alert.node.rules.yml=/opt/k8s/prometheus/file/alert.node.rules.yml

如需修改可使用kubectl edit 或者以下方式

删除现有的ConfigMap

kubectl delete configmap prometheus-config

使用新的文件重新创建ConfigMap

kubectl create configmap prometheus-config
–from-file=prometheus.yml=/path/to/new/prometheus.yml
–from-file=alert.mysql.rules.yml=/path/to/new/alert.mysql.rules.yml
–from-file=alert.node.rules.yml=/path/to/new/alert.node.rules.yml

部署Deployment

修改prometheus-Deployment.yaml文件中的信息，然后应用YAML文件

cat > /opt/k8s/prometheus/prometheus-Deployment.yaml <<EOF
apiVersion: apps/v1
kind: Deployment
metadata:
  name: prometheus-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: prometheus

        ports:
        -Port: 9090
        volumeMounts:
        - name: prometheus-config-volume
          mountPath: /etc/prometheus
          readOnly: true
        - name: prometheus-data
          mountPath: /prometheus
      volumes:
      - name: prometheus-config-volume
        configMap:
          name: prometheus-config
      - name: prometheus-data
        persistentVolumeClaim:
          claimName: prometheus-data-pvc
EOF

kubectl apply -f prometheus-Deployment.yaml 
kubectl get Deployment

部署Service

修改prometheus-Service.yaml文件中的信息，然后应用YAML文件

cat > /opt/k8s/prometheus/prometheus-Service.yaml <<EOF
apiVersion: v1
kind: Service
metadata:
  name: prometheus-service
spec:
  type: NodePort
  ports:
  - port: 9090
    targetPort: 9090
    nodePort: 30090
  selector:
    app: prometheus
EOF

kubectl apply -f prometheus-Service.yaml 
kubectl get Service
