This article uses the k8s cluster to build prometheus monitoring, and monitors some details such as k8s node nodes.
The format of this article is similar to the essay format, without detailed description.
For basic articles, you can check my previous blog.

Prometheus is best built in the k8s cluster (that is, in docker).
Some configuration files of prometheus can be found on github.
https://github.com/coreos/kube-prometheus
部署/root/kube-prometheus/manifests 目录下所有文件
kubectl apply -f /root/kube-prometheus/manifests/
部署/root/kube-prometheus/manifests/setup 目录下所有文件
kubectl apply -f /root/kube-prometheus/manifests/setup/
要注意的是自己要创建一个工作空间
如果报错执行下面语句
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_alertmanagerconfigs.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_alertmanagers.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_podmonitors.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_probes.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_prometheuses.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_prometheusrules.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_servicemonitors.yaml
kubectl apply -f https://raw.githubusercontent.com/prometheus-operator/prometheus-operator/release-0.43/example/prometheus-operator-crd/monitoring.coreos.com_thanosrulers.yaml
部署完之后可以执行下面命令查看状态
kubectl get pod -n monitoring
kubectl get svc -n monitoring
kubectl top node （如果不部署setup下的环境这里会出错）
The environment deployment is successful. The
default account password of grafana is admin.
