k8s之安装sonarqube

1.k8s安装sonarqube 记录，三个配置文件搞上来

首先是创建postgre的PV PVC 配置文件，kubectl apply -f  pvc-xxxxxx.yaml  这里的目的是让sonarqube的数据库postgresql 的数据持久化存储，不会因为pod删除而丢失，name 、path 可以自定义，这个type 还不太清楚具体的意义，貌似可有可无啊，后续尝试去掉进行部署

apiVersion: v1
kind: PersistentVolume
metadata:
  name: postgres-data
  labels:
    type: local
spec:
  storageClassName: manual
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/data/postgresql"

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: postgres-data
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi

2.k8s安装postgresql，kubectl apply -f  postgres（文件名称）.yaml   

apiVersion: apps/v1
kind: Deployment
metadata:
  name: postgres-sonar
spec:
  replicas: 1
  selector:
    matchLabels:
      app: postgres-sonar
  template:
    metadata:
      labels:
        app: postgres-sonar
    spec:
      containers:
      - name: postgres-sonar
        image: postgres:latest
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 5432
        env:
        - name: POSTGRES_DB
          value: "sonar"
        - name: POSTGRES_USER
          value: "sonar"
        - name: POSTGRES_PASSWORD
          value: "sonar"
        volumeMounts:
          - name: data
            mountPath: /var/lib/postgresql/data
      volumes:
        - name: data
          persistentVolumeClaim:
            claimName: postgres-data

---
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

3.k8s安装sonarqube，kubectl apply -f  sonarqube（文件名称）.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: sonarqube
spec:
  replicas: 1
  selector:
    matchLabels:
      app: sonarqube
  template:
    metadata:
      labels:
        app: sonarqube
    spec:
      containers:
      - name: sonarqube
        image: sonarqube:k8s
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 9000
        env:
        - name: SONARQUBE_JDBC_USERNAME
          value: "sonar"
        - name: SONARQUBE_JDBC_PASSWORD
          value: "sonar"
        - name: SONARQUBE_JDBC_URL
          value: "jdbc:postgresql://postgres-sonar:5432/sonar"

---
apiVersion: v1
kind: Service
metadata:
  name: sonarqube
  labels:
    app: "sonarqube"
spec:
  type: NodePort
  ports:
  - name: sonarqube
    port: 9000
    targetPort: 9000
    nodePort: 30003
    protocol: TCP
  selector:
    app: sonarqube

  注意：需要注意的地方就是SONARQUBE_JDBC_URL的配置，

jdbc:postgresql://postgres-sonar:5432/sonar postgres-sonar 是pg数据库的service 5432是端口 sonar是db 不要搞错

还有就是如果是半路移过来的镜像容易有问题，比如pg数据库数据丢失，sonarqube无法链接数据库等，建议使用新的镜像进行部署

常用命令

查看现有的node，服务，pod，deployment，PV，pvc，svc，sc等等

kubectl  get node   pod  service   pv   pvc   sc   svc   depyloyment

查看具体的namespace需要加上-n  空间名

kubectl get po -n default

查看pod的详细信息

kubectl describe pod xxxxxpod

通过配置文件进行应用部署

kubectl apply -f XXXXXX.yaml

通过配置文件进行删除部署

kubectl delete -f XXXXXX.yaml
