If you need cross-platform you probably won’t need Kubernetes. To a certain extent Docker feels like a defeat for people like me that worked so hard to make OSGi/Java as cross platform as possible. I do feel we solved most of the problems and there are many proof points that it actually does work.
Docker is the revenge of the messy people. Working with Java/OSGi requires that
a lot of things are done right while Docker allows you to create an identical
mess on any other computer. I do believe that there is value in doing it right
but it is a rather feeble argument once you see how much complexity is removed
from the picture.
So in JPM I experimented with winrun4j for the windows services. I know it
worked once but it had very little loving care in the last few years, and true,
I do detest windows so the urge to work with the \ is very low on my side.
So jpm4j clearly had the incentive to do exactly what you want for
cross-platform deploys. It seems to work quite well for commands but it did
also have a service model. It works for MacOS and Linux as far as I know.
So feel free to experiment with jpm4j this purpose. All its code is in the bnd
repository, including winrun4j. I gladly accept PRs are provide feedback if
you’re willing to put some time in it.
Then again, my personal focus is very much on Kubernetes because it seems that
most software in the future is either in the cloud or in the browser.
Kind regards,
