How to upload dashboards as .json files to kubernetes via helm

Yes we have now hit this limit and so are using the kiwigrid sidecar. Its actually not as complicated as I thought to set up, and it can be used for dashboards AND datasources (my initial concern de to that warning in my earlier post). So we use this now;

grafana:
  sidecar:
    dashboards:
      enabled: true
      searchNamespace: 'grafana'
      provider:
        name: sidecarProvider
        orgid: 1
        folder: ''
        type: file
        disableDelete: false
        allowUiUpdates: true
        foldersFromFilesStructure: false
    datasources:
      enabled: true
      label: "grafana_datasource"
      labelValue: ""

And the dashboards are loaded as individual config maps… the datasources as secrets - they must have the respective labels;

grafana_dashboard: "1"
grafana_datasource: "1"

Cheers.
