Reduce size of Docker image

[h-arlt]

At the moment, the size of Docker image is about 1.6GB which is much too big just for running a Java console app. Thus, we should consider various options to shrink it down to a few hundreds of megabytes.

Options:

• use size-optimized base image, e.g. Alpine Linux
• replace JDK with JRE
• get rid of Firefox ESR
• offer an image variant that does not install any browser (including their WebDriver servers) at all
• ...

Please don't use Alpine. It uses a different glibc and there are many problems coming and going for software on Alpine including JDK.

The OpenJDK port for Alpine is not in a supported release by OpenJDK,

since it is not in the mainline code base. Google runs distroless images to get them small.... https://github.com/GoogleContainerTools/distroless Might have to check which one is best: https://hub.docker.com/r/adoptopenjdk/openjdk11/
