ArtifactHub 为 Helm Chart 提供了公共和私有资源库。我们将使用这些 Helm Chart 来设置 Kubernetes 集群中的 pod 和服务。 Helm 社区为各种 Kubernetes 应用程序创建、管理和维护 Helm Chart这些资源会时常更新。Helm Chart 可重复使用安装简单。想要使用 Helm 在 Kubernetes 上集成 Prometheus 和 Grafana让我们从安装 Helm 开始。 安装 Helm
安装 Helm 之前必须使用以下命令启动 Minikube Kubernetes minikube start --driverdocker下图显示 Minikube 正在运行。Kubectl 工具现已配置为使用 Minikube。 接下来使用以下命令根据你使用的操作系统使用对应的命令安装 Helm 在 Linux 上安装 Helm sudo apt-get install helm在 Windows 上安装 Helm choco install Kubernetes-helm在 macOS 系统上安装 Helm brew install helm提示如果遇到问题可以查看 Helm 官方文档指南 https://helm.sh/docs/intro/install/。 下图显示了 Helm 在 Windows 机器上的安装情况 Helm 命令
要获取所有 Helm 命令请运行此命令 helm命令输出结果 The Kubernetes package managerCommon actions for Helm:- helm search: search for charts
- helm pull: download a chart to your local directory to view
- helm install: upload the chart to Kubernetes
- helm list: list releases of chartsUsage:helm [command]Available Commands:completion generate autocompletion scripts for the specified shellcreate create a new chart with the given namedependency manage a charts dependenciesenv helm client environment informationget download extended information of a named releasehelp Help about any commandhistory fetch release historyinstall install a chartlint examine a chart for possible issueslist list releasespackage package a chart directory into a chart archiveplugin install, list, or uninstall Helm pluginspull download a chart from a repository and (optionally) unpack it in local directorypush push a chart to remoteregistry login to or logout from a registryrepo add, list, remove, update, and index chart repositoriesrollback roll back a release to a previous revisionsearch search for a keyword in chartsshow show information of a chartstatus display the status of the named releasetemplate locally render templatestest run tests for a releaseuninstall uninstall a releaseupgrade upgrade a releaseverify verify that a chart at the given path has been signed and is validversion print the client version informationUse helm [command] --help for more information about a command.最常用的 Helm 命令有 helm search在 ArtifactHub 资源库中搜索 Helm Chart。helm pull从 ArtifactHub 资源库中提取并下载 Helm Chart。helm install上传 Helm Chart 并将其部署到 Kubernetes 集群。helm list列出 Kubernetes 集群中部署的所有 Helm Chart。 Prometheus Helm Charts
首先我们将搜索 Prometheus Helm Charts。要搜索 Prometheus Helm请运行以下命令 helm search hub prometheus该命令列出以下 Prometheus Helm Chart URL CHART VERSION APP VERSION DESCRIPTION

要公开prometheus-server Kubernetes service请运行以下命令 kubectl expose service prometheus-server --typeNodePort --target-port9090 --nameprometheus-server-ext该命令会将ClusterIP类型转换为NodePort类型。这样 prometheus-server就能在 Kubernetes 集群之外通过 9090 端口访问。 现在我们公开了prometheus-server Kubernetes service。接下来使用以下命令访问 Prometheus 应用程序 minikube service prometheus-server-ext该命令生成以下 URL URL 可能需要稍等一会儿才可用。您需要在浏览器上进行多次重试直到使用此 URL 访问 Prometheus Kubernetes 应用程序。您还需要保持终端打开并运行命令以便继续访问服务。 到这里我们已经成功使用 Helm 在 Kubernetes 上安装了 Prometheus。Prometheus 已经在集群内部运行我们可以使用浏览器或 URL 来进行访问。
