=== 环境准备 ===
* 关闭 selinux 及 firewalld
* 关闭 Swap
==== host ====
 192.168.0.158   np0
 192.168.0.229   np1
 192.168.0.249   np2
 192.168.0.148   np3

==== 设置网桥参数 ====
 cat << EOF > /etc/sysctl.d/99-kubernetes-cri.conf
 net.bridge.bridge-nf-call-ip6tables = 1
 net.bridge.bridge-nf-call-iptables = 1
 net.ipv4.ip_forward = 1
 user.max_user_namespaces=28633
 EOF
 
 sysctl -p /etc/sysctl.d/99-kubernetes-cri.conf

==== 配置支持 IPVS ====
加载 ip_vs 内核模块。kube-proxy 通过采用 iptables + ipset + ipvs 的方式实现为符合条件的 Pod 提供负载均衡。否则 kube-proxy 会退回到 iptables 模式。
 cat > /etc/modules-load.d/ip_vs.conf << EOF 
 ip_vs
 ip_vs_rr
 ip_vs_wrr
 ip_vs_sh
 nf_conntrack_ipv4
 EOF

 modprobe ip_vs
 modprobe ip_vs_rr
 modprobe ip_vs_wrr
 modprobe ip_vs_sh
 modprobe nf_conntrack_ipv4

==== 导入模块 ====
 cat << EOF > /etc/modules-load.d/containerd.conf
 overlay
 br_netfilter
 EOF

 modprobe overlay
 modprobe br_netfilter

 lsmod | grep overlay
 lsmod | grep br_netfilter
