脚本是不是需要完善一下，跟helm 版本也有问题吧。

hongming · 21 4月

xingxing122

是的，helm 版本需要 3.13+，我们调整一下脚本

xingxing122 · 21 4月

更新好了，可以说一下，谢谢，社区还是给力

hongming · 21 4月

xingxing122

kubesphere/ks-installer#2304
https://github.com/kubesphere/ks-installer/releases/tag/v4.1.3

更新一下 helm，再试试

helm 更新到了3.17之后，执行报错

hongming · 22 4月

xingxing122

kubectl get validatingwebhookconfiguration -o json | jq '.items[] | .webhooks[] | select(.clientConfig.service == null)'

这么检查看看，可以先把这些 validatingwebhookconfiguration clientConfig 中 service url 修改为 ServiceReference

已提交修复，kubesphere/ks-upgrade#27

xingxing122 · 22 4月

我这里是使用kubeconfig 文件连接的集群，url 中是集群名称，改为 ServiceReference 的时候， url": “https://gatekeeper-webhook-service.XXXtke集群.svc.cluster.local:18443/v1/admit” 这种格式，怎么改。

hongming · 22 4月

xingxing122

改一下 ks-upgrade 的 imagePullPolicy，重新拉一下镜像

编辑 ks-core-values.yaml，把 pullPolicy 改为 Always

upgrade:
  enabled: true
  image:
    registry: ""
    repository: kubesphere/ks-upgrade
    tag: ""
    pullPolicy: Always

xingxing122 · 22 4月

hongming 更新完毕之后，需要重新执行啥命令来加载一下呢，或者重新更新呢

xingxing122 · 22 4月

重新执行更新，还是报错，我的电脑是mac M1 系列，跟客户是啥系统没关系吧，看这个报错，还是空指针，哪里不对

检查一下 prepare-upgrade-xxxx pod 的 imagePullPolicy，镜像更新了没

    imageID: docker.io/kubesphere/ks-upgrade@sha256:bbdc80bbcab3f87b020af43d177c28425af593e103133ec6defdab9488dfb3a3

xingxing122 · 22 4月

hongming 更新了，还是这个问题，有点崩溃

xingxing122 · 22 4月

hongming 还有其他可以解决的么，升级之路太难了

hongming · 22 4月

xingxing122

确认一下 image hash 是否一致，我这能复现你遇到的问题，修复后也重新验证过，相关问题的修复记录 https://github.com/kubesphere/ks-upgrade/pull/27/files#diff-a539a85bdf77e6a269d56942c9ce3f56b0e1a0d33cf1ccd03ba6081f582a17dbR429

这一行的空指针加了前置判断，环境中配置的差异会被忽略

	/workspace/pkg/jobs/core/core.go:429 +0x22f

请提供一下最新的日志信息，可能不是这里产生的错误了

hongming · 22 4月

xingxing122

只能尽可能减少环境的差异，有一些特殊配置在升级过程中可能没有被覆盖到，但能根据异常日志定位到错误 https://github.com/kubesphere/ks-upgrade，比如你遇到的这个空指针问题，就可以稍微调整一下 validatingwebhook 的配置跳过

xingxing122 · 22 4月

镜像是一致的呢，我只是打的tag 传到的仓库而已，因为mac M1 系列的本地是拉取不到arm的镜像，所以需要传到我仓库去

hongming · 22 4月

xingxing122

是不是 retag 的时候搞错了，改了 imagePullPolicy也没拉到更新后的镜像，日志中的错误信息已经足够定位问题，你也可以自己去构建镜像试试。如果觉得麻烦，可以这么跳过，把导致异常的 validatingwebhook 先备份删除，升级完成后再恢复
