如何通过在Kubernetes上进行安装后访问Prometheus？

在Kubernetes集群中安装普罗米修斯使用：

helm install stable/prometheus 

它成功了：

 kubectl get pods NAME READY STATUS RESTARTS AGE winsome-otter-prometheus-alertmanager-3488774855-mk4ph 2/2 Running 0 5m winsome-otter-prometheus-kube-state-metrics-2907311046-ggnwx 1/1 Running 0 5m winsome-otter-prometheus-node-exporter-dp9b3 1/1 Running 0 5m winsome-otter-prometheus-pushgateway-3103937292-fvw8m 1/1 Running 0 5m winsome-otter-prometheus-server-2211167584-hjlp6 2/2 Running 0 5m kubectl get service NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.0.0.1 <none> 443/TCP 4d winsome-otter-prometheus-alertmanager ClusterIP 10.0.0.215 <none> 80/TCP 8m winsome-otter-prometheus-kube-state-metrics ClusterIP None <none> 80/TCP 8m winsome-otter-prometheus-node-exporter ClusterIP None <none> 9100/TCP 8m winsome-otter-prometheus-pushgateway ClusterIP 10.0.0.168 <none> 9091/TCP 8m winsome-otter-prometheus-server ClusterIP 10.0.0.62 <none> 80/TCP 8m 

如何从浏览器访问它？ 使用哪个端口？ 如何知道？

Answer 1

您需要先将端口9090从本地主机转发到prometheus吊舱：

 export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=server" -o jsonpath="{.items[0].metadata.name}") kubectl --namespace default port-forward $POD_NAME 9090 

现在你可以通过http：// localhost：9090上的浏览器访问Prometheus

您也可以为alertmanager做同样的alertmanager ：

 export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=alertmanager" -o jsonpath="{.items[0].metadata.name}") kubectl --namespace default port-forward $POD_NAME 9093 

现在Alertmanager可通过http：// localhost：9093上的浏览器访问

 NOTES: The Prometheus server can be accessed via port 81 on the following DNS name from within your cluster: voting-prawn-prometheus-server.default.svc.cluster.local Get the Prometheus server URL by running these commands in the same shell: export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=server" -o jsonpath="{.items[1].metadata.name}") kubectl --namespace default port-forward $POD_NAME 9091 The Prometheus alertmanager can be accessed via port 81 on the following DNS name from within your cluster: voting-prawn-prometheus-alertmanager.default.svc.cluster.local Get the Alertmanager URL by running these commands in the same shell: export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=alertmanager" -o jsonpath="{.items[1].metadata.name}") kubectl --namespace default port-forward $POD_NAME 9094 The Prometheus PushGateway can be accessed via port 9092 on the following DNS name from within your cluster: voting-prawn-prometheus-pushgateway.default.svc.cluster.local Get the PushGateway URL by running these commands in the same shell: export POD_NAME=$(kubectl get pods --namespace default -l "app=prometheus,component=pushgateway" -o jsonpath="{.items[1].metadata.name}") kubectl --namespace default port-forward $POD_NAME 9094 For more information on running Prometheus, visit: https://prometheus.io/
