Hello,

Could you please advise how to properly configure Keycloak in a single network?
When deploying the container and the code reaches the /ui/users/me endpoint, I receive a 500 error.

Main AuthType oidc
SsoApi User is now authenticated.

Note it has to end with a realm value if you work with Keycloak, for example: 'https://localhost:8180/auth/realms/quarkus'

You need to configure connection to keycloak using the following environment variables

KARAVAN_KEYCLOAK_URL=http://$YOUR_KEYCLOAK_HOST:$PORT
KARAVAN_KEYCLOAK_REALM=karavan
KARAVAN_KEYCLOAK_FRONTEND_CLIENTID=$FRONTEND_CLIENTID
KARAVAN_KEYCLOAK_BACKEND_CLIENTID=$BACKEND_CLIENTID
KARAVAN_KEYCLOAK_BACKEND_SECRET=$BACKEND_CLIENT_SECRET

Explanation of Variables:

1. KARAVAN_KEYCLOAK_URL: Replace $YOUR_KEYCLOAK_HOST and $PORT with the appropriate values for your Keycloak instance (not localhost).
2. KARAVAN_KEYCLOAK_REALM: This should be set to karavan or the specific realm you are using for your configuration.
3. KARAVAN_KEYCLOAK_FRONTEND_CLIENTID: Replace $FRONTEND_CLIENTID with the client ID configured for the frontend in Keycloak.
4. KARAVAN_KEYCLOAK_BACKEND_CLIENTID: Replace $BACKEND_CLIENTID with the client ID configured for the backend in Keycloak.
5. KARAVAN_KEYCLOAK_BACKEND_SECRET: Replace $BACKEND_CLIENT_SECRET with the secret key associated with the backend client.
