I'm deploying locally in docker-for-desktop. So that I can migrate to a kubernetes cluster in the future.

However I face a problem. Directories in the docker container/pod are over written, when persistent volumes are used.

I'm pulling the latest SonarQube image. A lot of plugins and quality profiles are pre-installed. Which is exactly what I want. If I don't use persistent volumes. Everything works as expected. When I use a pv all the data in the image is overwritten. I use helm.

In my deployment.yaml I use this:

 {{- if (eq .Values.volumes.usePersistent "true") }}
          volumeMounts:
          - mountPath: "/opt/sonarqube/data"
            name: sonarqube-data
          - mountPath: "/opt/sonarqube/extensions"
            name: sonarqube-extensions
      volumes:
      - name: sonarqube-data
        persistentVolumeClaim:
          claimName: sonarqube-data-pv-claim
      - name: sonarqube-extensions
        persistentVolumeClaim:
          claimName: sonarqube-extensions-pv-claim
{{- end }}

In my storage.yaml I use this:

{{- if (eq .Values.volumes.usePersistent "true") }}
kind: PersistentVolume
apiVersion: v1
metadata:
  name: sonarqube-data-pv-volume
  labels:
    type: local
    app: sonarqube-data
spec:
  storageClassName: manual
  capacity:
    storage: 2Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/tmp/toolbox/sonarqube/data"
---
kind: PersistentVolume
apiVersion: v1

    requests:
      storage: 2Gi
{{- end }}

The pvc are bounded and working. All the data that I need are in de 'data' and 'extensions' folder in the container, coming from the image. For example in the extensions folder:

sonarqube@sonarqube-deployment-6b8bdfb766-klnwh:/opt/sonarqube/extensions/plugins$ ls
README.txt               sonar-java-plugin-5.11.0.17289.jar      sonar-scala-plugin-1.5.0.315.jar

sonar-jacoco-plugin-1.0.1.143.jar    sonar-ruby-plugin-1.5.0.315.jar

I have made the following directories in my /tmp folder:

- data
- extensions
   - downloads
   - jdbc-driver
   - plugins

I know I must specify the same folders in my pv as in my container. I checked, all the folders are there in my /tmp folder. But are empty. They plugins folder is empty, all the plugin.jar files are gone.

BTW I did not include this in the initial post, but I'm using a PostgresDB also with pvc. pg-deploy.yaml:

{{- if (eq .Values.volumes.usePersistent "true") }} volumeMounts: - mountPath: /var/lib/postgresql/data name: sonarqubedb volumes: - name: sonarqubedb persistentVolumeClaim: claimName: postgres-sq-pv-claim {{- end }}

storage.yaml:

{{- if (eq .Values.volumes.usePersistent "true") }}
kind: PersistentVolume
apiVersion: v1
metadata:
  name: postgres-sq-pv-volume
  labels:
    type: local
    app: postgres-sonarqube

  storageClassName: manual
  capacity:
    storage: 2Gi
  accessModes:

  hostPath:
    path: "/tmp/toolbox/postgres-sonarqube"

{{- end }}
