基于k8s安装部署sonarqube

SonarQube需要依赖数据库存储数据，且SonarQube7.9及其以后版本将不再支持Mysql，所以这里推荐设置PostgreSQL作为SonarQube的数据库。

一，安装PGSql

apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgres-sonar
  labels:
    app: postgres-sonar
spec:
  replicas: 1
  selector:
    matchLabels:
      app: postgres-sonar
  template:
    metadata:
      labels:
        app: postgres-sonar
    spec:
      containers:
      - name: postgres-sonar
        image: postgres:11.4
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 5432
        env:
        - name: POSTGRES_DB
          value: "sonarDB"
        - name: POSTGRES_USER
          value: "sonarUser"
        - name: POSTGRES_PASSWORD 
          value: "123456"
        resources:
          limits:
            cpu: 1000m
            memory: 2048Mi
          requests:
            cpu: 500m
            memory: 1024Mi
        volumeMounts:
          - name: data
            mountPath: /var/lib/postgresql/data
      volumes:
        - name: data
          persistentVolumeClaim:
            claimName: postgres-data

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: postgres-data 
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: "gluster-heketi"
  resources:
    requests:
      storage: 1Gi

---
apiVersion: v1
kind: Service
metadata:
  name: postgres-sonar
  labels:
    app: postgres-sonar
spec:
  clusterIP: None
  ports:
  - port: 5432
    protocol: TCP
    targetPort: 5432
  selector:
    app: postgres-sonar

二，部署SonarQube

apiVersion: apps/v1
kind: Deployment
metadata:
  name: sonarqube
  labels:
    app: sonarqube
spec:
  replicas: 1
  selector:
    matchLabels:
      app: sonarqube
  template:
    metadata:
      labels:
        app: sonarqube
    spec:
      initContainers:
      - name: init-sysctl
        image: busybox
        imagePullPolicy: IfNotPresent
        command: ["sysctl", "-w", "vm.max_map_count=262144"]
        securityContext:
          privileged: true
      containers:
      - name: sonarqube
        image: sonarqube:lts
        ports:
        - containerPort: 9000
        env:
        - name: SONARQUBE_JDBC_USERNAME
          value: "sonarUser"
        - name: SONARQUBE_JDBC_PASSWORD
          value: "123456"
        - name: SONARQUBE_JDBC_URL
          value: "jdbc:postgresql://postgres-sonar:5432/sonarDB"
        livenessProbe:
          httpGet:

          initialDelaySeconds: 60
          periodSeconds: 30
          failureThreshold: 6
        resources:

          name: data
          subPath: extensions
      volumes:
      - name: data
        persistentVolumeClaim:
          claimName: sonarqube-data
