I installed prometheus-2.21.0 using helm charts. And trying to configure grafana to use prometheus as datasource.
datasources:
- access: proxy
editable: true
isDefault: true
jsonData:
timeInterval: 5s
name: Prometheus
orgId: 1
type: prometheus
url: [http://prometheus:9090](http://prometheus:9090)```
But, I’m getting the following error (from grafana pod log)
`error="http: proxy error: dial tcp: lookup prometheus on 10.96.0.10:53: no such host`
From grafana dashboard, if change the datasource url to `http://<prometheus_pod_ip>:9090>` its working.
But, whats wrong with the url `[http://prometheus:9090](http://prometheus:9090)` ?
