helm安装问题

• 标签: k8s

安装使用helm的时候，报错Error: could not find tiller

在安装了helm后，发现helm status后报错

helm status

->
Error: could not find a ready tiller pod

查找资料后解决了，详情如下：

  1. 获取k8s集群下pod的状态

    5
    kubectl get po -n kube-system

    ->
    NAME                                    READY     STATUS             RESTARTS   AGE
    tiller-deploy-675cbc8478-57kqz          0/1       ImagePullBackOff   0          7d

  2. 查看这个tiller的描述文件

发现是因为镜像下载的问题，那么可以用替代镜像的方式解决。

  1. 替换镜像，初始化helm

    helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.3 --stable-repo-url https://kubernetes.oss-cn-hangzhou.aliyuncs.com/charts

    ->
    $HELM_HOME has been configured at /Users/dillonliang/.helm.

稍等一会，发现helm可用了。
