Configure node labels and component arguments

The following command line arguments can be specified multiple times with key=value pairs:

• --kube-kubelet-arg
• --kube-proxy-arg
• --kube-apiserver-arg
• --kube-scheduler-arg
• --kube-controller-manager-arg
• --kube-cloud-controller-manager-arg
• --node-label
• --node-taint

In the config file, this is done by defining a list of values for each command like argument, for example:

---

k3s_server:
  # Set the plugins registry directory
  kubelet-arg:
    - "volume-plugin-dir=/var/lib/rancher/k3s/agent/kubelet/plugins_registry"
  # Set the pod eviction timeout and node monitor grace period
  kube-controller-manager-arg:
    - "pod-eviction-timeout=2m"
    - "node-monitor-grace-period=30s"
  # Set API server feature gate
  kube-apiserver-arg:
    - "feature-gates=RemoveSelfLink=false"
  # Laels to apply to a node
  node-label:
    - "NodeTier=development"
    - "NodeLocation=eu-west-2a"
  # Stop k3s control plane having workloads scheduled on them
  node-taint:
    - "k3s-controlplane=true:NoExecute"
