访问 kuboard-server 失败 http://kuboard-v3/kuboard-api/cluster/default/kind/KubernetesClusterToken
pod报错都一样: no route to host
原因:
找不到这个路由对应的地址,关闭防火墙,重启k8s,执行下面命令即可。
正常线上是不能关闭防火墙,这个属于pod内部之间的host调用失败,有大神知道的这种情况怎么处理的,
可以在评论区告知一下,谢谢

- 关闭防火墙,执行下前面命令
systemctl stop kubelet
systemctl stop docker
iptables --flush
iptables -tnat --flush
systemctl start kubelet
systemctl start docker
- 开放k8s对应的端口,上面报错是因为443、53端口没有开启
firewall-cmd --permanent --add-port=443/tcp
firewall-cmd --permanent --add-port=53/tcp
manager:
firewall-cmd --permanent --add-port=6443/tcp
firewall-cmd --permanent --add-port=2379-2380/tcp
firewall-cmd --permanent --add-port=10250-10252/tcp
firewall-cmd --reload
work nodes:
firewall-cmd --permanent --add-port=10250/tcp
firewall-cmd --permanent --add-port=30000-32767/tcp
firewall-cmd --reload
# 查看所有打开的端口:
firewall-cmd --zone=public --list-ports
