k8s部署prometheus和grafana部署修改prometheus的service类型为nodePort 修改

部署

git clone https://github.com/prometheus-operator/kube-prometheus.git

# 进入目录
[root@master ~]# cd kube-prometheus/

# 查找registry.k8s.io的镜像
[root@master kube-prometheus]# grep -r "registry.k8s.io" manifests/
manifests/kubeStateMetrics-deployment.yaml:        image: registry.k8s.io/kube-state-metrics/kube-state-metrics:v2.8.2
manifests/prometheusAdapter-deployment.yaml:        image: registry.k8s.io/prometheus-adapter/prometheus-adapter:v0.10.0

# 将registry.k8s.io修改为从阿里云下载
sed -i 's#registry.k8s.io/kube-state-metrics#registry.cn-beijing.aliyuncs.com/postkarte#g' manifests/kubeStateMetrics-deployment.yaml
sed -i 's#registry.k8s.io/prometheus-adapter#registry.cn-beijing.aliyuncs.com/postkarte#g' manifests/prometheusAdapter-deployment.yaml

# 应用yaml文件
kubectl create -f manifests/setup

修改下prometheus UI的service模式为nodePort(注意如果在公网环境不要这样操作，因为会直接登录可以操作)

kubectl -n monitoring patch svc prometheus-k8s -p '{"spec":{"type":"NodePort"}}'

查看端口


[root@node1 kube-prometheus]# kubectl get service -n monitoring  
prometheus-k8s          NodePort    10.108.168.160           9090:30951/TCP,8080:31215/TCP   3m25s

访问prometheus UI

http://172.16.21.135:30951/

修改grafana的service类型为nodePort

kubectl -n monitoring patch svc grafana -p '{"spec":{"type":"NodePort"}}'

查看grafana的端口

[root@node1 kube-prometheus]# kubectl get service -n monitoring 
grafana                 NodePort    10.108.14.132            3000:31635/TCP                  9m14s
