The node-local-dns module: configuration

This feature is available in Enterprise Edition only.

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

Set the spec.enabled module parameter to true or false to explicitly enable or disable the module.

Example of enabling the node-local-dns module:

          apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: node-local-dns
spec:
  enabled: true

        

Example of disabling the node-local-dns module:

          apiVersion: deckhouse.io/v1alpha1
kind: ModuleConfig
metadata:
  name: node-local-dns
spec:
  enabled: false

        

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

Pay attention to the following:

The module supports the iptables kube-proxy mode only (the ipvs mode is not supported and not tested).
By default, the module does not serve hostNetwork requests (they are forwarded to kube-dns). In this case, you can specify the 169.254.20.10address in the Pod configuration yourself. However, if a node-local-dns will crash, you will not be able to get back to kube-dns.
