vaadin and containers

anyone here is using vaadin in a realm environment with containers?

It took me two days to match the libraries to run spring, jetty, vaadin 14, keycloak with gradle: I’ve found only broken or incomplete examples so maybe I’m missing some guide or cookbook (?)

Now while the application works locally, I’m having some trobule create a docker image with Jib, and I can’t find working examples inside vaadin website about gradle+docker image … no definition of the requirements, or about how a production build works (the build works, the application crashes)

any hint?

Any joy? Facing that today.
