      <description>&lt;p&gt;我们知道， 使用 kubeadm 建立的 k8s 集群，master 节点会被标注上 node-role.kubernetes.io/master:NoSchedule 的 taint&lt;/p&gt;

&lt;p&gt;一种办法是将这个 taint 取消掉：&lt;/p&gt;

&lt;pre&gt;&lt;code&gt;kubectl taint nodes --all node-role.kubernetes.io/master-
&lt;/code&gt;&lt;/pre&gt;

&lt;p&gt;另一种方法是指定 toleration 描述让它能够容忍上面的 taint 。我觉得这种方式更好一些。&lt;/p&gt;

&lt;p&gt;&lt;/p&gt;</description>
