Jenkins POD 重启如何持久化 Jenkins 配置和插件

Question

我已经将我的 Jenkins 部署为 kubernetes yaml 文件的一部分，并且还启用了 Persist volume claim，当我的 Jenkins pod 重新启动时，我丢失了所有的作业和配置，这意味着我需要重新安装所有 Jenkins suggest 插件，配置 kubernetes 云，配置 git 存储库，并创建新的管道作业。

cloud你帮我看看如何避免上述情况。

vi jenkins-deployment.yaml

kind: Deployment
apiVersion: apps/v1
metadata:
  name: jenkins-master
  namespace: jenkins
  labels:
    app: jenkins-master
spec:
  replicas: 1
  selector:
    matchLabels:
      app: jenkins-master
  template:
    metadata:
      labels:
        app: jenkins-master
    spec:
      securityContext:
        fsGroup: 1000
      containers:
      - name: jenkins
        image: jenkins/jenkins:lts
        imagePullPolicy: Always
        ports:
        - containerPort: 8080
        - containerPort: 50000
        readinessProbe:
          httpGet:
            path: /login
            port: 8080
          initialDelaySeconds: 300
          periodSeconds: 10
          timeoutSeconds: 5
          successThreshold: 2
          failureThreshold: 5
        volumeMounts:
        - mountPath: "/var"
          name: jenkins-home
          subPath: jenkins_home
        resources:
          limits:
            cpu: 800m
            memory: 3Gi
          requests:
            cpu: 100m
            memory: 3Gi
      volumes:
      - name: jenkins-home
        persistentVolumeClaim:
          claimName: pvc-jenkins-home

vi jenkins-pvc.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-jenkins-home
  namespace: jenkins
spec:
  storageClassName: efs
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Mi

 kubectl get pvc -n jenkins
NAME               STATUS   VOLUME                                     CAPACITY   ACCESS MODES   STORAGECLASS   AGE
pvc-jenkins-home   Bound    pvc-4ccf3f55-6894-4fee-88d7-58dd7584b837   10Mi       RWO            efs            59m

如果我需要任何详细信息，请告诉我

Answer 1

请从 volumeMounts 中删除 subpath，因为子路径将覆盖 /var 目录下的所有内容。所以它应该是这样的

volumeMounts:
- mountPath: /var
  name: jenkins-home
