The module does not require any configuration (it works right out-of-the-box).

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/pod-reloader 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: pod-reloader
    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 pod-reloader
    

Example of disabling the module:

  • by using the ModuleConfig resource:

    apiVersion: deckhouse.io/v1alpha1
    kind: ModuleConfig
    metadata:
      name: pod-reloader
    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 pod-reloader
    

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

Example of the ModuleConfig/pod-reloader resource for configuring the module:

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

Parameters

Schema version: 1

  • settings
    object
    • settings.nodeSelector
      object

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

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

      Example:

      nodeSelector:
        disktype: ssd
      
    • settings.reloadOnCreate
      boolean

      Rollout the workload in case of creating a ConfigMap or Secret.

      Enabling the parameter will cause the workload to restart not only when changing the corresponding ConfigMap or Secret, but also when creating it.

      Default: true

      Examples:

      reloadOnCreate: true
      
      reloadOnCreate: false
      
    • settings.tolerations
      array of objects

      The same as in the pods’ spec.tolerations parameter in Kubernetes;

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

      Example:

      tolerations:
      - key: key1
        operator: Equal
        value: value1
        effect: NoSchedule
      - key: key1
        operator: Exists
        effect: NoSchedule
      
      • settings.tolerations.effect
        string
      • settings.tolerations.key
        string
      • settings.tolerations.operator
        string
      • settings.tolerations.tolerationSeconds
        integer
      • settings.tolerations.value
        string
