title: 1 node(s) had taints that the pod didn't tolerate in kubernetes cluster
body: <p>Today my kubernetes cluster v1.15.2 give me this error: <code>1 node(s) had taints that the pod didn't tolerate</code> and the pods could not start.</p>
  <p>It tells me one nodes have taints and I check the node status and works fine, how to know it exactly have taints?</p>
  <p>I am searching from internet and all tells me that master node could not allocate for pods running by default. But now my kubernetes pods is not running a master node.</p>
  <ul>
  <li>What may cause my node have taints(for example this node have not enough resource)?</li>
  <li>What should I do to find out the taints of the node and fix it?</li>
  </ul>
