在天蓝色下运行kubernetes 1.15。
当我的一个或多个应用程序/容器在kubernetes中关闭时，我需要一个基本警报（电子邮件/闲置通知）。
作为一个例子，我有https://cert-manager.io/docs/在多个群集中运行（托管在azure中），如果它停止运行，我希望收到警报（电子邮件/闲置通知）。
基于此帖子：
How do I set up a hook to send an email on Kubernetes pod restart?
似乎收到电子邮件警报，我需要安装Prometheus + Grafana访问Web界面并配置警报，因此基于：
https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack
https://artifacthub.io/packages/helm/prometheus-community/kube-prometheus-stack
我尝试过：
<div id="create"><a href="home.html">CREATE USER</a></div>
<div id="back"><b href="main.html">Go back to the homepage</b></div>但这给出了：
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
这里有一些有关如何手动创建crds的指南：
但这仅在运行helm 2.x（不是我正在运行3.1.2）时才是必需的。
如果我尝试手动安装它们，我也会得到：
Error: failed to install CRD crds/crd-alertmanager.yaml: unable to recognize "": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1"
我也找到了这个 kube-prometheus堆栈兼容性矩阵：
https://github.com/prometheus-operator/kube-prometheus#compatibility
但是该母舰中的版本与我得到的版本不匹配：
$ 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"
...
所以看来这可能是安装Prometheus的第三种方法
任何输入表示赞赏。
更新：
随机选择以前的主要版本（9.4.10）似乎可行：
$ helm search repo prometheus-community/kube-prometheus-stack --versions

在较旧的k8s版本上安装内容时，可以通过试错法来尝试，但是对于兼容性矩阵来说可能很好。

基于kube-prometheus-stack回购，此头盔图表仅限于K8s 1.16.0或更高版本；
kubeVersion：“> = 1.16.0-0”
即使github自述文件将先决条件表示为String _mi_email='';
String _mi_nombre='';
String _mis_apellidos='';
String _mi_foto='';
String _mi_clinica='';
String _mi_id='';
class HomeScreen extends StatefulWidget {
@override
_HomeScreenState createState() => _HomeScreenState();
}
class _HomeScreenState extends State<HomeScreen> {
void getValues() async {
SharedPreferences sharedPrefs = await SharedPreferences.getInstance();
_mi_email = sharedPrefs.getString('email');
_mi_clinica = sharedPrefs.getString('clinica') ?? "ninguna";
_mi_nombre = sharedPrefs.getString('nombre') ?? "ninguno";
_mis_apellidos = sharedPrefs.getString('apellidos') ?? "ningunos";
_mi_foto = sharedPrefs.getString('foto') ?? "ninguna";
_mi_id = sharedPrefs.getString('id') ?? "0";
}
@override
void initState() {
getValues();
super.initState();
}
@override
Widget build(BuildContext context) {
...
，但在helm图表内部也会检查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。
如果无法升级群集，则可以尝试使用不建议使用的旧版本。
