Build issue for the sample docker container

[nawaf-alnaji]

Hello,

The package does not seem to work, even in the sample docker. I've tried running it on both Mac OS and Linux, on multiple computers, with no luck. The keycloak container exits after the following error:

Docker 24.0, docker-compose v2.18.

Another error comes up when attempting to use the package in my own keycloak docker container.

Are there any required packages or prior set up that has been omitted from the documentation?

Thanks

Hey @nawaf-alnaji!

Can you please post your Dockerfile. From the stacktrace it looks like that you didn't copy the JAR file correctly. The path /opt/keycloak/lib/../providers/keycloak-home-idp-discovery.jar inside the container points to an empty directory.

The sample docker-compose file assumes that you have build the JAR file with Maven before starting it up.

Yeah, that was the issue. It just needed building.

Thanks for the quick reply.

There are pre-build versions available for download in the release section.
