I have set up an ELK cluster with OpenShift, including Elasticsearch in stateful mode and Kibana in a deployment. The issue I am facing is that we are using the free version of Elasticsearch, and I want to implement SSO, which is not possible with this version. Therefore, I have come up with the idea to set up a reverse proxy SSO with Nginx and Keycloak.

The problem that I faced is that in my OpenShift, I can’t use operators. What I did was pull the image from the Red Hat catalog and set up a PostgreSQL database. However, I don’t know what to do next or how it works, or which environment variables I should put in my deployment. I added KC_DB_USERNAME, KC_DB_PASSWORD, and KC_HOSTNAME, but the pod keeps failing.
i’m using this image :

Red Hat build of Keycloak image

this is the logs of the pod :

`Keycloak - Open Source Identity and Access Management
