Encapsulation 封装
官方文档
缺省模式，Cilium 会自动运行在封装模式下，因为这种模式对底层网络基础设施（特别是云厂商）依赖性比较低，只要2层网络通城，执行封装技术即可达到Pod通信目的
在这种模式下，所有集群节点使用基于 UDP 的封装协议 VXLAN 或 Geneve 形成隧道网状结构。 Cilium 节点之间的所有流量都被封装
二种封装技术
- VXLAN
- Geneve
如果你的网络有设置防火墙，注意了，这几个端口
| Encapsulation Mode | Port Range / Protocol |
|---|---|
| VXLAN (Default) | 8472/UDP |
| Geneve | 6081/UDP |
封装优势
- 简单
连接集群节点的网络不需要知道 PodCIDR。 集群节点可以产生多个路由或链路层域。 只要集群节点可以使用 IP/UDP 相互访问，底层网络的拓扑结构就无关紧要
- 寻址空间
由于不依赖于任何底层网络限制，如果 PodCIDR 大小相应地配置，可用寻址空间可能要大得多，并且允许每个节点运行任意数量的 Pod
- 自动配置
当与编排系统（例如 Kubernetes）一起运行时，集群中所有节点的列表（包括其关联的分配前缀节点）将自动提供给每个cilium-agent， 加入集群的新节点将自动合并到网格中
- identity context
封装协议允许将元数据与网络数据包一起携带。 Cilium 利用这种能力来传输元数据，例如源安全身份。 身份传输是一种优化，旨在避免在远程节点上进行一次身份查找
封装劣势
- MTU Overhead
由于添加了封装header，MTU太大引起的弊端低于本机路由（VXLAN 的每个网络数据包 50 字节）。 这导致特定网络连接影响低吞吐量。 当然可以通过启用巨型帧（每 1500 字节有 50 字节的开销，而每 9000 字节有 50 字节的开销）来很大程度上缓解。
配置过程
- 配置过程如下
helm install cilium cilium/cilium --version 1.9.9 \ --namespace kube-system \ --set tunnel=vxlan \ --set kubeProxyReplacement=strict \ --set ipam.mode=kubernetes \ --set ipam.operator.clusterPoolIPv4PodCIDR=172.21.0.0/20 \ --set ipam.operator.clusterPoolIPv4MaskSize=26 \ --set k8sServiceHost=apiserver.qiangyun.com \ --set k8sServicePort=6443
- 观察节点的路由，如下

# 说明
每个节点都有一个CiliumInternal地址 172.21.9.225
每个节点都有一个IPAM
每个节点都有一个healthcheck的地址

# 说明
cilium_host 类似于一个路由器，网关设备
cilium_net & cilium_host成对出现，像是一个veth，一端接容器一端接主机
cilium_vxlan 就是虚拟二层网络，用来提供Pod跨节点通信MTU封装 - 虽然cilium默认使用的封装技术，但是host routing模式还是使用到BPF模式，如下
