Fixes #10

Now image size (receiver) is 184Mb, compared to previous 478Mb

This is a first pass on the issue, there are some mods picked by jdeps that we could eventually remove (like java.sql, that we don't use but we bring in b/c of jackson-databind). Also, we're on ubuntu base, we could drill down the image even further porting to alpine (but that requires musl libc and we need to figure out how to make that working with jlink).

Proposed Changes

  • Use jlink to create a smaller jdk, in order to reduce image size of our deliverables

Ok it seems like the vert.x dns works, but it requires the module of the jdk dns, funky
