The module starts reading logs only if log-pipeline is created. Log-pipeline consists of ClusterLoggingConfig/PodLoggingConfig connected to ClusterLogDestination.

The module has 5 alerts.

The module is enabled by default in the following bundles: Default, Managed. The module is disabled by default in the Minimal bundle.

How to explicitly enable the module…

Set the spec.enabled module parameter to true or false in the ModuleConfig/log-shipper resource (create it, if necessary) to explicitly enable or disable the module, or use the deckhouse-controller module command in the d8-system/deckhouse pod.

Example of enabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: log-shipper
spec:
  enabled: true

  • by using the deckhouse-controller command (you need a kubectl, configured to work with the cluster):

    kubectl -ti -n d8-system exec svc/deckhouse-leader -c deckhouse -- deckhouse-controller module enable log-shipper

Example of disabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: log-shipper
spec:
  enabled: false

  • by using the deckhouse-controller command (you need a kubectl, configured to work with the cluster):

    kubectl -ti -n d8-system exec svc/deckhouse-leader -c deckhouse -- deckhouse-controller module disable log-shipper

Settings

The module is configured using the ModuleConfig custom resource named log-shipper (learn more about setting up Deckhouse…).

Example of the ModuleConfig/log-shipper resource for configuring the module:

apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: log-shipper
spec:
  version: 1
  enabled: true
  settings: # <-- Module parameters from the "Parameters" section below.

Parameters

Schema version: 1

  • settings
    object
    • settings.debug
      boolean

      Enable or disable agent debug logging. Default: false.

      Default: false

    • settings.nodeSelector
      object

      The same as in the Pods’ spec.nodeSelector parameter in Kubernetes.

      If the parameter is omitted or false, nodeSelector will be determined automatically.

    • settings.resourcesRequests
      object

      Max amounts of CPU and memory resources that the pod can request when selecting a node.

      If the vertical-pod-autoscaler module is disabled, then these values become the default ones.

      Examples:

      resourcesRequests:
  mode: VPA
  vpa:
    mode: Auto
    cpu:
      min: 50m
      max: 2
    memory:
      min: 256Mi
      max: 2Gi

      resourcesRequests:
  mode: VPA
  vpa:
    mode: Initial
    cpu:
      min: 1
      max: 3000m
    memory:
      min: 1024
      max: 4096

      resourcesRequests:
  mode: Static
  static:
    cpu: 55m
    memory: 256Ki
      • settings.resourcesRequests.mode
        string

        Required value

        Resource request management mode:

        • Static is a classic one. In it, you explicitly specify requests. The parameters of this mode are defined in the static parameter section;
        • VPA mode uses VPA. You can configure this mode by modifying parameters in the vpa parameter section.

        Default: VPA

        Allowed values: VPA, Static

      • settings.resourcesRequests.static
        object

        Resource request management options for the Static mode.

        • settings.resourcesRequests.static.cpu

          Required value

          Configuring CPU requests.

          Default: 50m

        • settings.resourcesRequests.static.memory

          Required value

          Configuring memory requests.

          Default: 64Mi

      • settings.resourcesRequests.vpa
        object

        Resource request management options for the VPA mode.

        • settings.resourcesRequests.vpa.cpu
          object

          Required value

          CPU-related parameters.

          • settings.resourcesRequests.vpa.cpu.max

            The maximum value that the VPA can set for the CPU requests.

            Default: 500m

          • settings.resourcesRequests.vpa.cpu.min

            The minimum value that the VPA can set for the CPU requests.

            Default: 50m

        • settings.resourcesRequests.vpa.memory
          object

          Required value

          The amount of memory requested.

          • settings.resourcesRequests.vpa.memory.max

            The maximum memory requests the VPA can set.

            Default: 2048Mi

          • settings.resourcesRequests.vpa.memory.min

            The minimum memory requests the VPA can set.
