Got 302 code when curl kibana ingress URL

Elastic Stack Kibana
1

my ELK stack is running in AKS, when I try to curl the Kibana ingress URL, I got 302 code and and I see it is redirected to /spaces/enter. I wonder why and how I can make it to work.

curl http:/app/kibana

Is this for a health check? Just curious about what goal we're looking for.

If it is I would recommend curl http://app/kibana/api/status

This is for accessing Kibana web site externally, i.e. from outside of the AKS. With the ingress rules, I should be able to access the Kibana site externally using "curl http:///app/kibana". But I got 404 error. When I tried to login to the Kibana container, and run "curl http://localhost:5601" , I got the same thing, i.e. it is redirected to /spaces/enter. I don't know why it is directed to /spaces/enter. Shouldn't it be redirected to the Kibana web site?

Below is from inside of the Kibana container, the output from running curl:
[ls4074@starfish etc]$ kubectl exec -it kibana-kibana-76c7d9fd6f-mwlkh -n elk -- curl -v http://localhost:5601

  • Connection #0 to host localhost left intact

However, if I run "curl http://localhost:5601/app/kibana, it returns the web content.
