过渡无压力！KubeSphere v3.4.x 到 v4.x 平滑升级全攻略

升级中有报错，这种资源没有被helm 管理的

检查一下日志 cat host-upgrade.log | grep "apply CRDs" -A 20

升级过程会有 prepare upgrade 这个步骤，你检查看看 https://github.com/kubesphere/ks-installer/blob/release-4.1/scripts/upgrade.sh#L180-L185

xingxing122

有没有脚本一次来处理这些不受helm 管理的资源呢。

xingxing122

我的集群是TKE上进行升级，

cat host-upgrade.log | grep "apply CRDs" -A 20

检查看看为什么这行命令为什么没有被执行， https://github.com/kubesphere/ks-installer/blob/release-4.1/scripts/upgrade.sh#L180-L185，脚本内容一致吗

helm template -s templates/prepare-upgrade-job.yaml -n kubesphere-system --release-name \
        --set upgrade.prepare=true,upgrade.image.registry=$IMAGE_REGISTRY,upgrade.image.tag=$KS_UPGRADE_TAG \
        $EXTENSION_REGISTRY_ARG \
        --set global.imageRegistry=$IMAGE_REGISTRY,global.tag=$TAG \
        -f ks-core-values.yaml \
        $chart --dry-run=server | kubectl -n kubesphere-system apply --wait -f - && kubectl -n kubesphere-system wait --for=condition=complete --timeout=600s job/prepare-upgrade

正常升级过程中应该有如下日志:

apply CRDs
configmap/ks-upgrade-prepare-config created
job.batch/prepare-upgrade created
persistentvolumeclaim/ks-upgrade created
job.batch/prepare-upgrade condition met

xingxing122

那我的升级过程就有问题，脚本没有执行这部分。有点奇怪，现在升级到一半了，如何重新升级

xingxing122

卡在这里了，我想重新从零开始升级，好像也不行，卡住了

hongming

xingxing122

ctrl + c 可以中断

hongming

xingxing122

你看看脚本内容一致吗，不应该少了这段命令 https://github.com/kubesphere/ks-installer/blob/release-4.1/scripts/upgrade.sh#L180-L185

xingxing122

hongming 中断了之后呢，我看pod 是pending 状态的，咋继续排查错误

hongming

xingxing122 upgrade.sh 可以重复执行的，脚本没有修改过吧？别把 set -e 去掉了，正常运行肯定会执行到上面我列出的这行命令

xingxing122

hongming 脚本是一致的，我对比了一下，下载文档说明的脚本

xingxing122

hongming 我之前用patch 打上helm 标签，我取消试试，for r in globalroles.iam.kubesphere.io globalrolebindings.iam.kubesphere.io workspacetemplates.tenant.kubesphere.io clusterroles.iam.kubesphere.io clusterrolebindings.iam.kubesphere.io; do \

kubectl get $r -o name | xargs -I{} kubectl label {} app.kubernetes.io/managed-by=Helm –overwrite; \

kubectl get $r -o name | xargs -I{} kubectl annotate {} meta.helm.sh/release-name=ks-core meta.helm.sh/release-namespace=kubesphere-system –overwrite; \

done

脚本没有修改过，我取消打的标签，重新跑一下脚本

xingxing122

有执行命令，但是看是报错了

review your upgrade values.yaml and make sure the extension configs matches the extension you published, you have 10 seconds before upgrade starts.

脚本是不是需要完善一下，跟helm 版本也有问题吧。

hongming

xingxing122

是的，helm 版本需要 3.13+，我们调整一下脚本

xingxing122

更新好了，可以说一下，谢谢，社区还是给力
