I am not 100% sure, that this is the right way to go about it, but I have a grafana deployment:

spec:
  volumes:
    - name: grafana-config
      configMap:
        name: grafana-configmap
    - name: default-dashboard
      configMap:
        name: default-dashboard
    - name: grafana-pv
      persistentVolumeClaim:
        claimName: grafana-pvc
  securityContext:
    runAsUser: 0
  containers:
    - name: grafana
      image: grafana/grafana:latest
      env:
        - name: GF_INSTALL_PLUGINS
          value: yesoreyeram-boomtheme-panel
      ports:
        - containerPort: 3000
      volumeMounts:
        - mountPath: "/var/lib/grafana"
          name: grafana-pv
        - name: grafana-config
          mountPath: /etc/grafana/provisioning/dashboards
        - name: default-dashboard
          mountPath: /var/lib/grafana/dashboards/

And in there I specify, that I want: default-dashboard, which contains the json of a grafana dashboard.

So, when I deploy grafana, I get a dashboard created for me, which is great.

The issue, that I want to address, is that there might be many apps, all wanting their own dashboard, and it doesn't seem reasonable to manually specify a volume mount, in the way that I have done now.

So is it somehow possible to automatically mount all configMaps? Preferably everything matching some selector?

Or is there any other way to deploy a dashboard in this way without the grafana.yaml being aware of every individual config map?
