href="https://www.treesir.pub/post/n1-openwrt-k3s-deploy/" target="_blank" >之前搭建</a> 的 k3s 集群中因为某些原因我将 openwrt 节点，进行了系统重装，更改固件为了 <code>esir</code> 高大全的 op 固件，由于其 固件中没有将 <code>vxlan</code> 模块编译进内核当中，而 k3s <code>默认</code> 使用的 cni 为 <code>flannel 的 vxlan</code> 模式，导致在初始化节点的时候会出现错误，导致节点添加不成功，我们知道原生 flannel 支持的模式不只单单只有 vxlan，还支持 <strong>host-gw</strong>、<strong>udp</strong> 模式。进行查阅 k3s 相关资料，看到 k3s 是支持切换多种网络模式的，于是决定将 flannel 模式更改为 <code>host-gw</code> 。</p>https://blog.treesir.pub/posts/n1-docker/Sun, 15 Nov 2020 16:09:10 +0800yangzun@treesir.pub
