kubernetes - 无法在 Kubernetes 集群上使用 helm chart 部署服务

问题描述

我正在尝试在 kubernetes 集群上使用 helm chart 部署服务。它抛出错误为

“错误：非绝对 URL 应采用 repo_name/path_to_chart 的形式，得到：留言簿”

这是我正在部署的留言簿服务https://github.com/phcollignon/helm/tree/master/lab5_helm_chart_version1/

提供者.helm v2.14.3

provider.kubernetes v1.16

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"16", GitVersion:"v1.16.0", GitCommit:"2bd9643cee5b3b3a5ecbd3af49d09018f0773c77", GitTreeState:"clean", BuildDate:"2019-09-18T14:36:53Z", GoVersion:"go1.12.9", Compiler:"gc", Platform:"linux/amd64"}

$ helm install guestbook

解决方案

有五种不同的方式可以表达要安装的图表：

  1. 通过图表参考：helm install stable/mariadb
  2. 通过打包图表的路径：helm install ./nginx-1.2.3.tgz
  3. 通过解压图表目录的路径：helm install ./nginx
  4. 通过绝对 URL：helm install https://example.com/charts/nginx-1.2.3.tgz
  5. 通过图表参考和回购网址：helm install --repo https://example.com/charts/ nginx

有使用选项号3的示例

使用以下命令下载 github 存储库：

git clone https://github.com/phcollignon/helm

然后进入lab5_helm_chart_version1文件

cd helm/lab5_helm_chart_version1

并且只需使用 helm install 创建留言簿

helm install chart/guestbook/ --name guestbook
