Keycloak.X Property replacement via environment variables not working

[Benjamin Weimer]

Hi,

as described here [1] it should be possible to use environment variables
to define properties in keyclock.properties. Property replacement works
fine with system properties but sadly not with environment variables. Is
this currently broken or do I need to do anything special to use the
environment variable mechanism?

Kind regards
Benjamin

Hey Benjamin,

thanks for reaching out! Could you pls describe:

a) which version you are using? 15.0.2 or latest main? There were tons of changes.

b) the steps you have tried? There's no generally known bug for this atm.

Best regards,

Dominik

Hi Dominik,

I used Keycloak version 15.0.2 and did something like adding a property in keycloak.properties:

spi.hostname.default.frontend-url=${env.MY_KC_URL}

Then I set MY_KC_URL environment variable and run kc.sh to start Keycloak.X. The property was treated as empty.

Kind regards
Benjamin

It should suffice to just remove the env..., so instead of 

spi.hostname.default.frontend-url=${env.MY_KC_URL}

please try 

spi.hostname.default.frontend-url=${MY_KC_URL}

and set the environment variable

Ahh okay, thanks I'll try that. Is it possible to update the documentation in this case? https://github.com/keycloak/keycloak-community/blob/main/design/keycloak.x/configuration.md#property-replacement
