docker images *21.6-bookworm
REPOSITORY   TAG             IMAGE ID       CREATED       SIZE
node         21.6-bookworm   505e9f3603f0   3 weeks ago   1.1GB

the base image is quite big;
I chose it as a base for all our node applications. The reason is that we find ourself debugging something and it's good that it has most tools installed ;
I know all the good practice mention to make the image as small as possible; I just wanted to make our lives easier since we still develop the applications :)

if we refactor bundler we should refactor all docker images on the sam base
