My first step was something even simpler than the obligatory ‘Hello World’, just print the Java version. I picked openjdk:alpine because its description sounded pretty good : “Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.” Create a simple image that prints the java version The official java image for Docker is deprecated and the openjdk image is suggested as its successor. I wanted a light weight image with just a jdk. It still has a few rough edges on the networking part, but good enough to use during development or create images that will run on a Linux production environment.
