Kubernetes :主机名regex失败

Question

尝试运行kubeadm init

[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 ~]#

在主机名上显示错误。我可以在这台机器上运行kudeadm吗？

Answer 1

您可以按照reference manual中的说明对--api-external-dns-names使用主机名以外的其他名称。例如：

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

这应该运行得很好。

您还可以更改机器的主机名-在SO too上有很多方法可以做到这一点。
