Container whisperer You deploy across clouds like it’s second nature. Docker listens, Kubernetes obeys, and somehow it all just works.

What a fantastic fit πŸ€—

Since I was called out in person during the talk I should probably share it, too :-)

Jokes aside. This talk is an excellent reference for @graalvm.org and you all should watch it!

But of course it depends on the app. The analysis of the apps with jdeps will define which components of the JRE are required. And jlink will build it on exactly that requirements then

It depends on a couple of things. Jib has a default image, with jlink/jdeps you need to provide your own. If you keep those identical, you can see the difference in the JRE layer. In my case it was a difference of about 150MB, if I remember correctly

I stare out of it and watch the world go by.

Very interesting talk if you're building container images - especially for the JVM. I had not really explored buildpacks for this. Definitely gave me some things to think about
