Please help me.

I use bitnami/keycloak:26.3.2

Answered by mabartos

Aug 15, 2025

Why is kc.http-relative-path = (ENV) empty?

Does Bitnami handle env vars in a way that it sets the ENV var even when there's no value? IMO, the env var should not be set at all if an empty value is provided to use KC defaults.

Can you provide your configuration? Or just check your keycloak relative path settings or if you setting the quarkus.management.root-path property directly. The error is saying that via one of these mechanisms the property has an empty string value, which is not valid.

@Holubinka Unfortunately none of that configuration at first glance is related to the relative path. It would be best to try to reproduce this independently of the helm chart. Are you able to change the run command to kc.sh show-config - that will make it clearer what is actually be supplied to Keycloak.

@mabartos I never added KEYCLOAK_HTTP_RELATIVE_PATH. In bitnami/keycloak, it is always set by default. The same applies to KEYCLOAK_CACHE_TYPE. However, when I manually specified it, everything worked as expected.

@Holubinka I'd suspect that's the bug in Bitnami itself as they do not properly handle these env vars. There might be some issues with their custom mappings of KEYCLOAK_HTTP_RELATIVE_PATH --> KC_HTTP_RELATIVE_PATH (supported by Keycloak), as we don't support prefix KEYCLOAK_ in env vars.
