Kubernetes 无法在k8s 1.15中安装kube prometheus堆栈

在azure中运行kubernetes 1.15

当我的一个或多个应用程序/吊舱在kubernetes停机时，我需要一个基本警报（电子邮件/松弛通知）

例如，我在多个集群中运行（托管在azure中），如果它停止运行，我希望收到警报（电子邮件/松弛通知）

根据这篇文章：

它似乎收到了一封电子邮件警报，我需要安装Prometheus+Grafana访问web ui并根据以下内容配置警报：

我试过：

helm version
version.BuildInfo{Version:"v3.1.2", GitCommit:"d878d4d45863e42fd5cff6743294a11d28a9abce", GitTreeState:"clean", GoVersion:"go1.13.8"}


helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo add stable https://kubernetes-charts.storage.googleapis.com/
helm repo update

helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack --namespace monitoring

但这给了：

Error: failed to install CRD crds/crd-alertmanager.yaml: unable to recognize "": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1"

这里有一些关于如何手动创建CRD的指南：

但只有在运行helm 2.x（我不是在运行3.1.2）时才有必要这样做

此外，如果我尝试手动安装它们，我会得到：

$ kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.42/example/prometheus-operator-crd/monitoring.coreos.com_alertmanagers.yaml
error: unable to recognize "https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.42/example/prometheus-operator-crd/monitoring.coreos.com_alertmanagers.yaml": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1"
$ kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.42/example/prometheus-operator-crd/monitoring.coreos.com_podmonitors.yaml
error: unable to recognize "https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.42/example/prometheus-operator-crd/monitoring.coreos.com_podmonitors.yaml": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1"
$ kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.42/example/prometheus-operator-crd/monitoring.coreos.com_prometheuses.yaml
error: unable to recognize "https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.42/example/prometheus-operator-crd/monitoring.coreos.com_prometheuses.yaml": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1"
...

我还发现了这个库贝普罗米修斯堆栈兼容性矩阵：

但是matris中的版本与我得到的版本不匹配：

$ helm search repo prometheus-community/kube-prometheus-stack --versions
NAME                                        CHART VERSION   APP VERSION DESCRIPTION

prometheus-community/kube-prometheus-stack  10.0.1          0.42.1      kube-prometheus-stack collects Kubernetes manif...

看来这可能是安装普罗米修斯的第三种方法

欢迎您的任何意见

更新：

随机选择以前的主要版本（9.4.10）似乎有效：

$ helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack --namespace monitoring --version 9.4.10

猜测在旧版k8s上安装东西时，尝试和错误是一种方法，但兼容矩阵可能非常好。

基于kube prometheus堆栈回购，此头盔图表仅适用于k8s 1.16.0或更高版本

kubeVersion:“>=1.16.0-0”

尽管github自述文件称先决条件为带有Beta API的Kubernetes 1.10+，但helm图表在内部检查kube版本是否为1.16.0或更高版本

所以我相信，您需要在升级的K8s集群上尝试这一点

如果升级集群不是一个选项，那么您可以尝试使用不推荐使用的旧版本

不推荐的旧版本可能匹配-我添加了上面的链接来回答。啊，考虑到最新版本预期为1.16或更高版本，这也很好。有人否决了答案，也许他们可以在这样做的时候给出一个理由作为评论。不推荐的版本对我有用。只是提醒一下，不要使用头盔安装稳定/普罗米修斯使用头盔安装普罗米修斯社区/普罗米修斯，因为图表已经移动。非常感谢。你的回答帮助我学习EKS 1.14和helm3。
