Disable login kibana 8.2

We are using eck operator and oauth2-proxy for single sign on. And we want to disable the kibana login page so that after successful sign in, oauth2 directly will take the user to dashboard. But how should we do that? when we do xpack.security.disabled: false on Elasticsearch.yml, It gives error:

{"timestamp": "2022-05-12T15:15:24+00:00", "message": "readiness probe failed", "curl_rc": "35"}

Why use an oauth proxy when Kibana can do oauth natively?

Yes, this was the way it was setup previously in our company so we thought we could just replicate it on kubernetes. But we can use the native one also. But just curious, how can we disable the login on kibana ?

With eck, idk if that's possible.

Even when i try to do oauth natively, It asks for xpack.security.authc.realms.oidc.oidc1.rp.client_secret which needs to be stored in keystore as per documentation. But how would I be able to enter my client_secret in keystore using just yaml files?

U can create a k8s secret with the value and then add it to the config. See Secure settings | Elastic Cloud on Kubernetes [2.2] | Elastic
