K8s系列之： lookup bigdata1 on 8.8.8.8:53: no such host

出现如下报错：

[preflight] Running pre-flight checks
[WARNING Hostname]: hostname “bigdata1” could not be reached
[WARNING Hostname]: hostname “bigdata1”: lookup bigdata1 on 8.8.8.8:53: no such host

解决方法是：确保主机名称与IP有映射关系
/etc/hosts如下所示：

 cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.216.128 bigdata1
192.168.216.129 bigdata2
192.168.216.130 bigdata3
192.168.216.131 bigdata4
192.168.216.132 bigdata5
192.168.216.133 ubuntu1

192.168.238.1 bigdata
192.168.216.134 bigdata6

/etc/resolv.conf如下所示：

cat /etc/resolv.conf
