* bootstrap-node-taints | string

  Space-separated list of taints to apply to this node at registration time.

  This config is only used at bootstrap time when Kubelet first registers the
  node with Kubernetes. To change node taints after deploy time, use kubectl
  instead.

  For more information, see the upstream Kubernetes documentation about
  taints:
  https://kubernetes.io/docs/concepts/scheduling-eviction/taint-and-toleration/
* kube-proxy-extra-args | string

  Space separated list of flags and key=value pairs that will be passed as arguments to
  kube-proxy.

  For example a value like this:
  runtime-config=batch/v2alpha1=true profiling=true
  will result in kube-proxy being run with the following options:
  --runtime-config=batch/v2alpha1=true --profiling=true
* kubelet-extra-args | string

  Space separated list of flags and key=value pairs that will be passed as arguments to
  kubelet.

  For example a value like this:
  runtime-config=batch/v2alpha1=true profiling=true
  will result in kubelet being run with the following options:
  --runtime-config=batch/v2alpha1=true --profiling=true
* node-labels | string

  Labels can be used to organize and to select subsets of nodes in the
  cluster. Declare node labels in key=value format, separated by spaces.

  Note: Due to NodeRestriction, workers are limited to how they can label themselves
