node加入集群时如何自动添加taints/labels

register node with taints

有时我们需要在创建node时候就已经带上labels/taints,而不是等node加入集群后再加labels/taints(也就是)
taints
在/var/lib/kubelet/config.yaml中添加registerWithTaints,如
kubelet 添加命令行参数register-with-taints,如

--register-with-taints=demokey=demovalue:PreferNoSchedule

registerWithTaints:
- key: demokey
  value: demovalue
  effect: PreferNoSchedule

如果是kubeadm部署,可以使用JoinConfiguration,添加内容如下

nodeRegistration:
  taintstaints:
  - key: demokey
    value: demovalue
    effect: PreferNoSchedule

register node with labels

kubelet 添加命令行参数,如

--node-labels=demokey=demovalue

如果是kubeadm部署,可以使用JoinConfiguration,添加内容如下

nodeRegistration:
  kubeletExtraArgs:
  - node-labels: demokey=demovalue
