大家好，我是博哥爱运维。

这节课我们用prometheus-operator来安装整套prometheus服务

https://github.com/prometheus-operator/kube-prometheus/releases

开始安装

1. 解压下载的代码包
wget https://github.com/prometheus-operator/kube-prometheus/archive/refs/tags/v0.13.0.zip
unzip kube-prometheus-0.13.0.zip
rm -f kube-prometheus-0.13.0.zip && cd kube-prometheus-0.13.02. 这里先看下有哪些镜像
# find ./ -type f |xargs egrep 'image: quay.io|image: registry.k8s.io|image: grafana|image: docker.io'|awk '{print $3}'|sort|uniqquay.io/prometheus-operator/prometheus-config-reloader:v0.67.1  # 注意：这个镜像配置比较特殊，上面命令过滤不出来grafana/grafana:9.5.3
docker.io/cloudnativelabs/kube-router
quay.io/brancz/kube-rbac-proxy:v0.14.2
quay.io/fabxc/prometheus_demo_service
quay.io/prometheus/alertmanager:v0.26.0
quay.io/prometheus/blackbox-exporter:v0.24.0
quay.io/prometheus/node-exporter:v1.6.1
quay.io/prometheus-operator/prometheus-operator:v0.67.1
quay.io/prometheus/prometheus:v2.46.0
registry.k8s.io/kube-state-metrics/kube-state-metrics:v2.9.2
registry.k8s.io/prometheus-adapter/prometheus-adapter:v0.11.1# 由于上面的镜像中，有部分国内网络无法正常摘取，所以博哥将上述所有镜像已转存至docker hub上，用下面命令批量替换下镜像地址即可find ./ -type f |xargs  sed -ri 's+quay.io/.*/+docker.io/bogeit/+g'
find ./ -type f |xargs  sed -ri 's+docker.io/cloudnativelabs/+docker.io/bogeit/+g'
find ./ -type f |xargs  sed -ri 's+grafana/+docker.io/bogeit/+g'
find ./ -type f |xargs  sed -ri 's+registry.k8s.io/.*/+docker.io/bogeit/+g'3. 开始创建所有服务
kubectl create -f manifests/setup
kubectl create -f manifests/
过一会查看创建结果：
kubectl -n monitoring get all
kubectl -n monitoring get pod -w# 附：清空上面部署的prometheus所有服务：
kubectl delete --ignore-not-found=true -f manifests/ -f manifests/setup

访问下prometheus的UI

# vim prometheus-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:name: prometheus
spec:rules:- host: prometheus.boge.comhttp:paths:- backend:service:name: prometheus-k8sport:number: 9090path: /pathType: Prefix# kubectl -n monitoring apply -f prometheus-ingress.yaml

grafana ingress创建

# vim grafana-ingress.yaml
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:name: grafana
spec:rules:- host: grafana.boge.comhttp:paths:- backend:service:name: grafanaport:number: 3000path: /pathType: Prefix# kubectl -n monitoring apply -f grafana-ingress.yaml

注意：删除自带的网络策略，否则访问服务都会被阻塞

kubectl -n monitoring delete networkpolicies.networking.k8s.io --all
