部署到一个k8s集群
git clone -b release-0.12 https://github.com/prometheus-operator/kube-prometheus.git
cd kube-prometheus
grep "image:" ./manifests/ -R国内无法下载的镜像：
以8s.gcr.io开头 k8s.gcr.io/kube-state-metrics/kube-state-metrics:v2.5.0 k8s.gcr.io/prometheus-adapter/prometheus-adapter:v0.9.1
apply如果报 too long: must have at most 262144b bytes 字节太长。则create命令创建
manifests # kubectl create -f setup/
manifests # kubctl apply -f .
kubectl get pods -n monitoring
kubectl get configmap -n monitoring # 配置文件爆露prometheus端口

export NODE_IP=$(kubectl get nodes -o jsonpath="{.items[0].status.addresses[0].address}")获取 NodePort
export NODE_PORT=$(kubectl -n monitoring get services prometheus-k8s -o jsonpath="{.spec.ports[0].nodePort}")获取 Address

kubectl delete -f prometheusAdapter.networkPolicy.yaml

kubectl get networkpolicies.networking.k8s.io -n monitoring
pllicyTypes:二进制部署prometheus：
prometheus.io/download/ # prometheus官网地址
mkdir /apps
cd //usr/local/src
wget -c https://github.com/prometheus/prometheus/releases/download/v2.42.0/prometheus-2.42.0.linux-amd64.tar.gz
tar xf prometheus-2.42.0.linux-amd64.tar.gz
mv prometheus-2 .42.0.linux-amd64 /apps
ln -sv /apps/prometheus-2 .42.0.linux-amd64 /apps/prometheus
cd /apps/prometheus
./prometheus --web.enable-lifecycle重启
--web.enable-lifecycle 改配置文件直接reload不需要重启
具体步骤如下：
- 在Prometheus的配置文件（
prometheus.yml）中开启HTTP服务的生命周期接口（--web.enable-lifecycle）。 - 向Prometheus发送POST请求，执行热加载操作，例如：
curl -X POST http://localhost:9090/-/reload这将会重新加载配置文件，并立即生效。
请注意，使用生命周期接口时需要谨慎。任何具有访问权限的人都可以使用该接口重新加载配置文件，因此需要采取相应的安全措施以避免滥用。
