Question

我无法在localhost：nodePort上访问kubernetes服务，但可以在127.0.0.1:nodePort上访问它。我也可以通过masterip：nodePort

这样的浏览器访问服务

以下输出

[root@k8s-master ~]# kubectl get services
NAME         TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
kubernetes   ClusterIP   10.96.0.1       <none>        443/TCP        4h26m
nginx        NodePort    10.109.106.21   <none>        80:30893/TCP   7m24s
[root@k8s-master ~]# curl -I 127.0.0.1:30893

^C

现在我担心如果localhost无法正常工作，是因为我的网络没有针对k8集群正确配置如何解决此问题。

有一个已报告的旧问题here，似乎与您的问题有关。

因此，可能与IPv6有关，一种解决方案是在<AdditionalDependencies>lz32.lib;wsock32.lib;odbc32.lib;odbccp32.lib;%(AdditionalDependencies)</AdditionalDependencies>命令的每次执行中添加--ipv4选项，或者通过禁用主机应用永久解决方案完全是IPv6。

无法访问localhost
