问题描述

ipv6 环境部署失败。

重现方法

centos7.9 下使用bcs-ops部署双栈环境集群会失败。

内核版本: 3.10

类似问题

flannel-io/flannel#1671

可能的修复方式

KERNEL_VERSION="3.10.0"
目前内核检测中只要求 3.10 (centos7 默认内核版本)。

bcs-ops 默认使用的 vxlan 模式,对于 ipv6 内核版本预检至少要求 4.19.1 . 目前在5 .4 版本上验证是成功的。

参考信息:
https://github.com/torvalds/linux/blob/v3.11/drivers/net/vxlan.c
https://github.com/torvalds/linux/blob/v3.12/drivers/net/vxlan.c

可见至少 3.12 后 vxlan 才支持 ipv6.

https://github.com/tigera/docs/blob/main/calico/networking/configuring/vxlan-ipip.mdx
tigera/docs#515

这里的验证描述中,4.19.1
