使用calico安装双栈集群
- 前置条件
- sealos 版本 >=4.3.0
- 每个主机都有一个IPv4主机和IPv6地址,并且可以互通通过IPv4和IPv6地址
- calico采用vxlan模式， 内核版本必须大于 3.12。 可以参考官方文档
- 运行
sealos gen生成一个 Clusterfile，例如：
$ sealos gen labring/kubernetes:v1.26.1 labring/helm:v3.10.3 labring/calico:v3.25.0 --masters 192.168.0.10 --nodes 192.168.0.11 --passwd "xxx" >Clusterfile
注意：labring/helm 应当在 labring/calico 之前。
生成的 Clusterfile 如下：

- 生成 Clusterfile 后，编辑Clusterfile,然后添加IPv6 的 pod 和svc 的 CIDR 范围。这里使用fd85:ee78:d8a6:8607::1:0000/112、fd85:ee78:d8a6:8607::1000/116作为参考示例。主要修改以下信息。
