Hi all I have a question to the feature “scripts” - I have enabled the feature in my Dockerfile and when I build it I found in logs “INFO [org.keycloak.common.Profile] (build-38) Preview feature enabled: scripts” In the new Admin-GUI under enabled Feature I can see the Feature “scripts” is enabled. But when I clone a Authentication Flow and want to add a “Authenticator Execution” I can not found in the provider List “Script” - not in the new or old admin GUI. What I’ve done wrong? ---

Scripts have to be deployed to the server’s file system, packaged in a jar file: [https://www.keycloak.org/docs/latest/server\_development/index.html#\_script\_providers](https://www.keycloak.org/docs/latest/server_development/index.html#_script_providers) Then the authenticator appears with its name (the one you gave it in the keycloak-scripts.json file) in the provider list. ---

Hi @mbonn get it. Now I try to build a script - or better first want to import a script that I think was working with other - and used the Script here: [http://forum.keycloak.org/t/trouble-getting-custom-authentication-script-deployed/15664](http://forum.keycloak.org/t/trouble-getting-custom-authentication-script-deployed/15664) Jar looks like: jar tf my-role-based-authenticator.jar - META-INF/ - META-INF/MANIFEST.MF - META-INF/keycloak-scripts.json - my-role-based-authenticator.js I linked it in docker-container to providers and set the user (key cloak:keycloak). Than I also rebuild the image (./kc.sh build). But can not found the the script on providers (nor under Server Information \> Providers) Could it be the script is not connect? Or any other clever hint from you? 😉 ---

PS on “bin/kc.sh show-config” I can see: kc.provider.file.my-role-based-authenticator.jar.last-modified = 1663758669402 (PersistedConfigSource) So think in general the script should loaded. ---

Do you have any error or warning entires in your logs? What is the content of keycloak-scripts.json? Do you run a JDK version different from 11? (Script engine has to be manually added on newer Java versions…)? Have you tried a maximal simple authenticator (just doing a context.success() within the authenticate(…) method)? Or tried a primitive JS token mapper? Is that working? If you try without docker on a bare metal setup, is it working then? ---

My failure - I use a Dockerfile and build a custom docker Image. When I import a script and rebuild it will affect in this. When I import a script with the Dockerfile and build my container than it works. ---

Yeah, everything is so much easier with docker… ---

So you can’t use the base image from [quay.io](http://quay.io) and you have to build your own dockerfile? So if the server says this: > 2022-10-20 09:02:37,845 INFO [io.quarkus] (Shutdown thread) Keycloak stopped in 0.177s > Changes detected in configuration. Updating the server image. > Updating the configuration and installing your custom providers, if any. Please wait. > 2022-10-20 09:02:44,184 INFO [org.keycloak.common.Profile] (build-95) Preview feature enabled: scripts > 2022-10-20 09:02:50,643 INFO [io.quarkus.deployment.QuarkusAugmentor] (main) Quarkus augmentation completed in 8888ms > Server configuration updated and persisted. Run the following command to review the configuration: > > kc.sh show-config > > Next time you run the server, just run: > > kc.sh start --optimized Then its actually not doing what it is supposed to do “Installing your custom providers” and it needs to be done in the dockerfile? Geez. * * * EDIT: Same here, I can see the custom\_providers jar. ```auto kc.provider.file.custom_providers.jar.last-modified = 1666256440343 (PersistedConfigSource) ``` ---

Weird, can’t seem to get it to work even with build… ```auto FROM quay.io/keycloak/keycloak:19.0.3 as builder WORKDIR /opt/keycloak ENV KC_HEALTH_ENABLED=True ENV KC_METRICS_ENABLED=True ENV KC_FEATURES=authorization,account2,admin2,account-api,docker,impersonation,web-authn,client-policies,ciba,par,step-up-authentication,scripts,preview ENV KC_DB=postgres # Install providers COPY ./deploy_custom_providers/*.jar providers/ RUN curl -sL https://github.com/aerogear/keycloak-metrics-spi/releases/download/2.5.3/keycloak-metrics-spi-2.5.3.jar -o providers/keycloak-metrics-spi-2.5.3.jar RUN /opt/keycloak/bin/kc.sh build FROM quay.io/keycloak/keycloak:19.0.3 WORKDIR /opt/keycloak COPY --from=builder /opt/keycloak . # change these values to point to a running postgres instance ENV KC_DB_URL=jdbc:postgresql://db/keycloak ENV KC_DB_USERNAME=keycloak ENV KC_DB_PASSWORD=REDACTED ENV KC_HOSTNAME=REDACTED ENTRYPOINT ["/opt/keycloak/bin/kc.sh"] CMD ["start", "--auto-build"] ``` ---

It should pop up here, if I am correct. ![image](https://global.discourse-cdn.com/free1/uploads/keycloak/original/2X/a/a4f70552df5f59c4f9bc88ffecf49f7394fcaad7.png) ---

My .jar file had an extra folder in it /build\_folder/META-INF I generated the jar with ansible, so i needed to fix the ansible command it it created it the right way, and I can use the [quay.io](http://quay.io) image and don’t have to build it myself. ---

Did you manage to make the final dockerfile? I’m having trouble how to make the dockerfile with keycloak image and my own scripts. ---

I used the [quay.io](http://quay.io) image in the end.
