      • CustomCertificate — webui/status will use HTTPS using the certificate from the d8-system namespace.

    • settings.smokeMini.storageClass

      A StorageClass to use when checking the health of disks.

      If omitted, the StorageClass of the existing PVC is used. If there is no PVC yet, either the global StorageClass or global.discovery.defaultStorageClass is used, and if those are undefined, the emptyDir volume is used to store the data.

      global.discovery.defaultStorageClass is applied during module activation, changing default StorageClass in cluster won’t result in disk re-provisioning.

      Setting it to false forces the use of an emptyDir volume.

      Default: false

      Examples:

      storageClass: false
      

      storageClass: default
      

  • settings.smokeMiniDisabled

    boolean

    Disables smokeMini.

    Disables “synthetic” probe group in Upmeter as well.

    Disables authorization for the status domain.

    Default: false

  • settings.storageClass

    The name of StorageClass that will be used in the cluster by default.

    The name of the StorageClass to use. If omitted, the StorageClass of the existing PVC is used. If there is no PVC yet, the StorageClass will be used according to the global storageClass parameter setting.

    The global storageClass parameter is only considered when the module is enabled. Changing the global storageClass parameter while the module is enabled will not trigger disk re-provisioning.

    If false is specified, emptyDir will be forced to be used.

    Warning. Specifying a value different from the one currently used (in the existing PVC) will result in disk re-provisioning and all data will be deleted.

    Warning. When migrating Upmeter with local storage to other nodes, the pods will enter a Pending state. In this situation, it will be necessary to back up the Upmeter database, delete the old PVCs, and manually restart the pod. Here, local storage refers to a StorageClass associated not with network storage but with a local volume on a node (for example, a StorageClass created by the local-path-provisioner module).

    Examples:

    storageClass: false
    

    storageClass: default

    tolerations:
    - key: key1
      operator: Equal
      value: value1
      effect: NoSchedule
