Current progress - created a test job on Jenkins: https://jean.bcvsolutions.eu/job/docker-images-test/
The job should (in the end) be triggered by the nightly build job (https://jean.bcvsolutions.eu/view/Product/job/czechidm-product-develop-build/) and use the war produced by the job as a base for the docker image.

The job is currently failing trying to fetch the war from Nexus:
