I’d be happier if this could run as one binary without Docker. Java is so much harder to setup.
However, there is a dedicated Dockerfile for creating a native image (Java words for "binary") that shouldn't require a JVM. I haven't tested running the binary myself so it's possible there are dependencies I'm not aware of, but I'm pretty sure you can just grab the binary out of the container image and run there locally if you want to.
It'll produce a Linux image of course, if you're on macOS or Windows you'd have to create a native image for those platforms manually.
Downloading JDK, setting up the correct env variables, or running Docker, all this is just pain, compared to single binary approach.
On my Mac Docker runs Linux virtualized. It’s a resource hog.
Compare that with simple native binary.
