  • kk最新版本支持集群开启IPV6/IPV4双栈吗？

24sama 这个service也是这样配置的。通过ipvsadm -L -n可以看到通过clusterIp的轮询配置了。

看配置是正确的，而且通过nodeport方式，通过主机IPv6地址和端口 [fd15:4ba5:5a2b:1008:5bbf:f87b:b3f7:dd1d]:31363是可以访问到pod的，但是就是在集群内部通过clusterIp和端口[2001:db8:42:1::7e3d]:80访问的时候，只有轮询到本节点上的pod的时候才能通，轮询到其他节点上的pod的时候就通不了，这个很奇怪

      tttt 这个是用的k8s官网上的service地址段和pod地址段吧，官网上这两个ipv6的地址段是有重合的，要修改一下，就可以通了。pod的包含了service的。

          2 年 后

          能否出个kk改造ipv4/ipv6双栈的教程？非常感谢！
