在尝试使用helm安装weave-scope时遇到错误，原因是Kubernetes版本与yaml文件中的apiVersion不兼容。解决方案是手动下载并解压图表包，将所有yaml文件中的v1beta1替换为v1，特别地，daemonset.yaml中的extensions/v1beta1需改为apps/v1，然后成功安装。

执行helm install ui aliyun/weave-scope时报错

报错情况如下：

[root@k8smaster ~]# helm install ui aliyun/weave-scope 
Error: INSTALLATION FAILED: unable to build kubernetes objects from release manifest: [resource mapping not found for name: "weave-scope-agent-ui" namespace: "" from "": no matches for kind "ClusterRole" in version "rbac.authorization.k8s.io/v1beta1"
ensure CRDs are installed first, resource mapping not found for name: "ui-weave-scope" namespace: "" from "": no matches for kind "ClusterRoleBinding" in version "rbac.authorization.k8s.io/v1beta1"
ensure CRDs are installed first, resource mapping not found for name: "weave-scope-agent-ui" namespace: "" from "": no matches for kind "DaemonSet" in version "extensions/v1beta1"
ensure CRDs are installed first, resource mapping not found for name: "weave-scope-frontend-ui" namespace: "" from "": no matches for kind "Deployment" in version "apps/v1beta1"
ensure CRDs are installed first]

原因：K8s中RBAC权限处理在Kubernetes的1.5版本中引入，在1.6版本时升级为Beta版本，在1.8版本时升级为GA…… weave版本低，k8s版本高，k8s版本和安装的yaml文件中对应的apiVersion版本不对，版本不兼容，根据报错情况修改即可。

解决：

无法直接安装，就先将包下载到当前目录.

[root@k8smaster ~]# helm pull aliyun/weave-scope 
[root@k8smaster ~]# ls | grep weave
weave-scope-0.9.2.tgz

解压这个包【若提示xxx不可信的旧时间戳，无所谓的不用管它】

[root@k8smaster ~]# tar zxvf weave-scope-0.9.2.tgz

进入解压出来的文件夹，根据报错内容执行

[root@k8smaster ~]# cd weave-scope
[root@k8smaster weave-scope]# grep -r v1beta1
charts/weave-scope-agent/templates/clusterrole.yaml:apiVersion: rbac.authorization.k8s.io/v1beta1
charts/weave-scope-agent/templates/clusterrolebinding.yaml:apiVersion: rbac.authorization.k8s.io/v1beta1
charts/weave-scope-agent/templates/daemonset.yaml:apiVersion: extensions/v1beta1
charts/weave-scope-frontend/templates/deployment.yaml:apiVersion: apps/v1beta1

将所有对应yaml中的...v1beta1，更换成...v1即可

需要注意的是：daemonset.yaml文件中的extensions/v1beta1务必改成apps/v1

【其它文件的修改，正常修改为...v1即可，不在此过多展示】

修改完成后，回到weave-scope文件夹的所在目录，再进行安装。

[root@k8smaster weave-scope]# cd ..
[root@k8smaster ~]# ls | grep weave-scope
weave-scope
[root@k8smaster ~]# helm install  ui  weave-scope
