确认配置是否生效
kubectl get sc
安装KubeSphere
KubeSphere目前还不支持kubernetes 1.22,这部分内容稍后就来...
安装Kubernetes集群监控prometheus-operator
查看集群信息
kubectl cluster-info
克隆prometheus-operator
git clone https://github.com/prometheus-operator/kube-prometheus.git
cd kube-prometheus
创建namespace, CustomResourceDefinitions & operator pod
因为原配置里面的好多镜拉取不下来,因此应用修改过的配置文件(当前目录下的kube-prometheus)
kubectl apply -f manifests/setup
查看namespace
kubectl get ns monitoring
查看pod
kubectl get pods -n monitoring
应用部署配置文件
kubectl apply -f manifests/
查看pods,svc
kubectl get pods,svc -n monitoring
调整SVC访问方式
Prometheus:
kubectl --namespace monitoring patch svc prometheus-k8s -p '{"spec": {"type": "NodePort"}}'
Alertmanager:
kubectl --namespace monitoring patch svc alertmanager-main -p '{"spec": {"type": "NodePort"}}'
Grafana:
kubectl --namespace monitoring patch svc grafana -p '{"spec": {"type": "NodePort"}}'
查看端口
$ kubectl -n monitoring get svc | grep NodePort
alertmanager-main NodePort 10.96.212.116 <none> 9093:30496/TCP,8080:30519/TCP 7m53s
grafana NodePort 10.96.216.187 <none> 3000:31045/TCP 7m50s
prometheus-k8s NodePort 10.96.180.95 <none> 9090:30253/TCP,8080:30023/TCP 7m44s
