安装istio后pod重新初始化istio-init报错，节点的iptables模块未被加载

[li-sen]

问题原因：iptables模块未被加载，所以我们可以尝试在所有k8s集群节点上加载iptables模块
[root@k8s-master kube]# modprobe ip_tables
[root@k8s-master kube]# modprobe iptable_filter
[root@k8s-master ~]# lsmod |grep -E "ip_tables|iptable_filter"
iptable_filter 16384 0
ip_tables 28672 2 iptable_filter,iptable_nat

docker exec -it kubeadm-ha sh -c "ansible -i my-cluster/inventory.ini all -m shell -a 'modprobe ip_tables;modprobe iptable_filter'"
docker exec -it kubeadm-ha sh -c "ansible -i my-cluster/inventory.ini all -m shell -a 'echo ip_tables >> /etc/modules-load.d/10-k8s-modules.conf;echo iptable_filter >> /etc/modules-load.d/10-k8s-modules.conf'"
