Different API Docker vs Ubuntu?

Hello there,
we are currently setting up Metasfresh in conclusion with our own webstore.
We have a docker container and also an other installation on an Ubuntu Server. When entering the Metasfresh API Side there are different API methods e.g. on out Ubuntu system “order-candidates-rest-controller-impl” this one does not exist on out docker installation. Is there any comparable methods in docker?
We want our users to be stored in Metasfresh as the first step and found the “order-…” as one suitable solution, are there any other for docker?
Thanks and have a nice day.
