What happened: Loading subscription from Azure when you try to configure Azure datasource, give you weird response from /api/datasources/proxy/1/azuremonitor/subscriptions/
What you expected to happen : Loading subscription
How to reproduce it (as minimally and precisely as possible) :
- Run Grafana in GCP Cloud Run (default configuration)
- Add datasource azure (fill tenant id, client secret, client id)
- Open Chrome/Firefox console (tab network)
- Click on “Load Subscriptions”
- Look the response
Anything else we need to know? : This is a very weird issue BUT I’ve try many things
- this happens ONLY in Cloud Run. With the same Grafana image local or gcp compute instance → no issue
- I’ve try to load subscription from azure SDK + using httputil.ReserveProxy (like Grafana does) → I can get the Azure response without issue
- Other datasource (Loki/Stackdriver/Cloudwatch/Prometheus) work well
- If I use a wrong client ID for Azure, I get a good response (valid JSON with 401 status code)
Furthermore, I can give access to a cloud run environnement if necessary or access to Azure (privately of course)
Request send by the front
Response received (obviously not a valid json)
