1.helm 介绍
Helm 是一个 Kubernetes 包管理器，可以用于简化 Kubernetes 应用程序的部署和管理。Helm 可以将 Kubernetes 应用程序打包为 chart，然后将这些 chart 分享和分发给其他人。
Chart 是一组预定义的 Kubernetes 资源模板，可以通过 Helm 进行部署和管理。Helm 还提供了一些有用的命令行工具，例如 helm install、helm upgrade 和 helm rollback，可以帮助您轻松地部署和管理 Kubernetes 应用程序。
Helm 还支持使用 chart 之间的依赖关系，这使得可以将多个 chart 组合在一起以部署更复杂的应用程序。
2.在 mac 上安装 helm
2.1 下载 helm tar 包
有几种方式安装 helm，这里我选择了下载包安装。首先，需要在 Helm GitHub 存储库的 Releases 页面上找到要安装的版本的 tarball 文件的 URL。可以在以下链接中找到 Helm 存储库的 Releases 页面：Releases · helm/helm · GitHub
curl -LO https://get.helm.sh/helm-v3.1.0-darwin-amd64.tar.gz2.2 解压 tar 包
tar -zxvf helm-v3.1.0-darwin-amd64.tar.gz 2.3 移动文件到 bin 目录下
解压缩后，我们会得到一个名为 darwin-amd64 的目录，其中包含 Helm CLI 可执行文件。可以将该目录移动到 PATH 中，以便在终端中使用 Helm CLI。例如，可以使用以下命令将该目录移动到 /usr/local/bin 目录中：
sudo mv darwin-amd64/helm /usr/local/bin/helm2.3 验证安装是否成功
可以使用以下命令来验证 Helm CLI 是否已成功安装：
helm version如果一切正常，您应该能够看到 Helm CLI 的版本信息。
