After development using Docker and docker compose I’ m trying a first test of a java application on local kubernetes.
For deployment I use this (example found online) and everything works fine

I would like to get rid of zookeeper and deploy kafka in kraft mode (as I did in docker compose file). I couldn’t find anything and I couldn’t figure out how to modify the deployment file. Who knows how to?
Many thanks
