Keycloak statup option --hostname-port is deprecated and disabled by default since keycloak 25.0.0

[HerrDerb]

Since keycloak 25.0.0. hostname:v1 is disabled by default. Therefor the dev service will fail to start if useSharedNetwork evaluates to true

    ...
    if (keycloakX) {
                addEnv(KEYCLOAK_QUARKUS_ADMIN_PROP, KEYCLOAK_ADMIN_USER);
                addEnv(KEYCLOAK_QUARKUS_ADMIN_PASSWORD_PROP, KEYCLOAK_ADMIN_PASSWORD);
                withCommand(startCommand.orElse(KEYCLOAK_QUARKUS_START_CMD)
                        + (useSharedNetwork ? " --hostname-port=" + fixedExposedPort.getAsInt() : ""));
                addUpConfigResource();
            }
    ...

Log output from the failed container:
Disabled option: --hostname-port. Available only when hostname:v1 feature is enabled
Possible solutions: --hostname, --hostname-admin, --hostname-backchannel-dynamic, --hostname-strict, --hostname-debug
Try kc.sh start --help for more information on the available options.
Specify --help-all to obtain information on all options and their availability.

Might actually not be relevant for you as we use our own image... If you already enabled --features=hostname:v1 in the default keycloak dev service image, feel free to close this issue

[andrejpetras]

Workaround that works for me:

quarkus.keycloak.devservices.show-logs=true
quarkus.keycloak.devservices.start-command=start --http-enabled=true --hostname-strict=false --features=hostname:v1

It seems like integration tests for Keycloak DevServices are missing.

[sberyozkin]

@andrejpetras We do have them, but not for the shared network case, we actually used to have them but they got accidentally dropped during some restructuring. I think we can hopefully fix this issue by reintroducing them

[joggeli34]

Any news about this? With keycloak 26, the hostname:v1 got removed and is therefore not an option as workaround anymore

[HerrDerb]

Seems to be resolved by past changes

[HerrDerb]

@sberyozkin Now with keycloak 26 hostname:v1 got dropped.
The usage within the keycloak devservice of --hostname-port is still present, therefor, upgrade to keycloak 26 is blocked.

[HerrDerb]

I intended to try if it works when the port gets set directly with the hostname, which should be valid

if (useSharedNetwork) {
                hostName = ConfigureUtil.configureSharedNetwork(this, "keycloak");
                if (keycloakX) {
                    addEnv(KEYCLOAK_QUARKUS_HOSTNAME, "localhost:" + fixedExposedPort.getAsInt());
                } else {
                    addEnv(KEYCLOAK_WILDFLY_FRONTEND_URL, "http://localhost:" + fixedExposedPort.getAsInt());
                }
            }

But my system won't let me 🤦‍♂️ I need to try after the weekend.

[HerrDerb]

@sberyozkin seems like I am currently having issue coming from by #45496

[HerrDerb]

Wrong button :)

[sberyozkin]

Thanks @HerrDerb for looking into this issue, and hopefully the linked one will be resolved soon for you to be able to continue

[HerrDerb]

@sberyozkin I did come myself as far as #45793 (comment) getting the localhost/127.0.0.1:35271
Therefor we might close this issue in favor for #45793 as it seems to contains more information and attention 👍
