Would it be worth adding a "didn't find it, couldn't patch" style warning or error here?

this is confusing a bit as the user has to do "gradle jar" at least least before this is executed. Without doing "jar", what you copy will not contain "sidecar.version" and then it all passes but it fails to start like this

I suggest we switch to ghcr.io/kafbat/kafka-ui.
That is the fork of provectuslabs, provectuslabs is not longer developed (last change 2 years ago, kafbat is actively developed). Both are Apache licenced. It is same UI etc ...

it would be nice if there is some way to also have "stop" script.

What am I supposed to do when it is all started and I want to just stop it. Doing docker-compose down on my own? "stop.sh" is more intuitive. "stopping" should also ideally remove the containers, I would like to not see see Exited containers in "docker ps"
|
I suggest to also include this to make it more robust. I like to be explicit in the creation of a topic. If somebody starts the stack and goes to kafka-ui then there will not be any topic for them to see messages in which might be confusing. |
