As someone who has worked extensively with containers but not with Java, what does this do to support Kubernetes? Is this just about making the runtime Docker friendly?
The JRE already is Docker aware and Docker friendly in regards to CPU and memory limits. And since Java 10 (March 2018), you do not need to manually configure anything for it to be that way.
Others already explained it better than I can but here I go: This is simply a new web framework (like Spring or vertx). The exciting thing about it is that it is using GraalVM / AOT magic and starts up very fast. Drawback is it requires custom libraries for stuff like Hibernate.
