Hi !
we are using docker images to run a pipeline on directory projects.
Those images are built using maven:3-jdk-${JDK_VERSION}, wouldn't it be
lighter to use maven:3-jdk-${JDK_VERSION}-slim ?
Sure, we can try. However keep in mind that only for JDK 8 and 11 such
slim images exist, they are based on Debian. The JDK 14 image is based
on Oracle Linux.
There is a openjdk 14 images that uses debian buster slim :

Now, here is how much is saved.... (I have tried with MINA) :
$ docker images

Reason is that the the Maven images themself are based
on the JDK images.
Do you want to try?
I'll give it a try with ApacheDS.
