  <p>I search from internet and find the reason is: should give all etcd node ip in hosts config when generate CA cert,but I config all my etcd node ip in csr.json,this is my csr.json config:</p>
  
  <pre><code>{
      "CN": "kubernetes",
      "hosts": [
        "127.0.0.1",
        "172.19.104.230",
        "172.19.150.82",
        "172.19.104.231"
      ],
      "key": {
          "algo": "rsa",
          "size": 2048
      },
      "names": [
          {
              "C": "CN",
              "ST": "BeiJing",
              "L": "BeiJing",
              "O": "k8s",
              "OU": "System"
          }
      ]
  }

  <p>what should I do to fix the error?</p>
