Kubernetes：主机名正则表达式失败

Question

试图运行kubeadm初始化

[root@ts_kubernetes_setup ~]# kubeadm init 
[kubeadm] WARNING: kubeadm is in alpha, please do not use it for production clusters. 
[preflight] Running pre-flight checks 
[preflight] WARNING: firewalld is active, please ensure ports [6443 9898 10250] are open or your cluster may not function correctly 
[preflight] Some fatal errors occurred: 
     hostname "ts_kubernetes_setup.localdomain" must match the regex [a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)* (e.g. 'example.com') 
[preflight] If you know what you are doing, you can skip pre-flight checks with `--skip-preflight-checks` 
[root@ts_kubernetes_setup ~]# 

显示的主机名错误。我可以在这台机器上运行kudeadm吗？

Answer 1

如reference manual中所述，您可以使用主机名以外的其他名称与--api-external-dns-names。例如：

kubeadm init --api-external-dns-names=kube.local 

这应该运行得很好。

您也可以更改机器的主机名 - 在SO too上您会找到很多方法来完成此操作。
