Configure app loggers

Hybrid mapping

As per v1.0.1, hybrid persistence supports all available persistence types. To configure hybrid persistence and its data mapping, follow the steps below:

  1. Set CN_PERSISTENCE_TYPE environment variable to hybrid

  2. Set CN_HYBRID_MAPPING with the following format:

    {
        "default": "<couchbase|ldap|spanner|sql>",
        "user": "<couchbase|ldap|spanner|sql>",
        "site": "<couchbase|ldap|spanner|sql>",
        "cache": "<couchbase|ldap|spanner|sql>",
        "token": "<couchbase|ldap|spanner|sql>",
        "session": "<couchbase|ldap|spanner|sql>",
    }
    

    Example:

    {
        "default": "sql",
        "user": "spanner",
        "site": "ldap",
        "cache": "sql",
        "token": "couchbase",
        "session": "spanner",
    }
    

Keycloak Administration

Admin Credentials

By default, Keycloak's admin username and password are self-generated during the first installation and saved as kc_admin_username (in the cn configmap) and kc_admin_password (in the cn secret) respectively. Note that the secret is base64 encoded.

The credentials will be rendered as /etc/jans/conf/kc_admin_creds file (can be changed via CN_SAML_KC_ADMIN_CREDENTIALS_FILE environment variable) with the following format:

BASE64(username:password)

The credentials will be exported as KEYCLOAK_ADMIN and KEYCLOAK_ADMIN_PASSWORD environment variables for the initial admin username and password.
