观测源码仓obs编译结果，发现报错
Unsupported host arch. Must be x86_64, 386, arm, arm64, s390x or ppc64le.
于是翻找源码并且尝试加入linux/riscv64的支持
在网络上搜索 "k8s 编译 Unsupported arch" 后，我得到如下搜索结果
http://liupeng0518.github.io/2019/05/15/k8s/deploy/%E6%BA%90%E7%A0%81%E7%BC%96%E8%AF%91/
根据此篇教程进行源码的修补，报错更改为
go not found
问题十分简单，在安装golang时并没有加入环境变量。
$ vim /var/tmp/build-root/standard_riscv64-riscv64/etc/profile
加入go的PATH
export GOROOT=/usr/lib/golang
export GOPATH=$HOME/golang
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
现在找得到go了
之后又出现报错
go build runtime/cgo: invalid flag in go:cgo_ldflag: -Wl,-z,relro,-z,now
在 kubernetes.spec 中删除编译参数 -Wl,-z,relro,-z,now 后，编译器不再报错，开始正常编译
之后 go compiler 报错：Undefined parseCPUInfo
在源码中寻找这一段，发现是因为 cpuinfo 的函数没有连接到 parseCPUInfoRISCV 的文件
$ vim cpuinfo_riscv64.go
并引入函数
package procfs
var parseCPUInfo = parseCPUInfoRISCV
遂正常编译
编译到一半报错硬盘空间不足，按照下面的教程实现了扩容qcow2
https://gitee.com/jinjuhan/open-euler-notes/blob/main/resize-qcow2.md
方便好用
obs 远端和本地同时报错：找不到 cgo
操作发现有 cgo 😓
尝试更改 kubernetes.spec 文件，添加
$ export CC="riscv64-linux-gnu-gcc"
无效
尝试直接修改 go env ，结果以失败告终
好像cgo找不到并不是一个严重的问题，即使作为一个error，它依然允许程序继续运行下去，出现了新的错误信息

找了一大圈子，感觉错误原因十分模糊，于是查看 go 的版本，发现为 1.15.5
因为是 go 编译时报错，怀疑可能是版本过低部分功能并不稳定，尝试将其更新到 1.18

结果编译报错找不到 atomic 包
真的服了，然后我一方面通过 obs 在编译环境上安装，一方面在本地环境安装，防止出错
obs构建 libatomic_ops 把我的 golang 删了，我又不缺那点内存😄
在多次找不到 libatomic 后，我把 go env 中的 CGO_ENABLE=1 改成0
编译成功，成功安装了最新的go1.18
现在尝试使用go1.18对kubernetes进行编译

编译成功，由于 Mainline 没有 go1.18，故尝试使用 1.17.3 进行在线构建
好消息，1.17.3 构建成功
现在开始进行PR的合并，先去 conf 仓库添加包的支持
fork 包到本地仓库，加入自己的 patch、spec 和 changelog
将其导入到 obs 中进行构建，构建成功后就可以申请PR的合并
合并后将 _service 的 git 仓库指向官方仓/oe-rv中间仓，触发obs的自动构建
自动构建成功后，就能通过obs提交了
至此，修包流程结束。
