No optimization api in own docker installation

We installed openrouteservice using the Dockerfile. We have no success using the optimization api. Our goal is, to find the minimal route to 50-200 adresses.
Is there any additional action needed to get running?

How can I check if vroom is installed in my container?

The optimisation itself is not part of the openrouteservice core - our optimisation endpoint is a self hosted instance of Vroom. If you want to have route optimisations on your own installation then you will need to install Vroom yourself ( on your servers and set it up as described in their documentation

Many thanks, we will try to integrate vroom and vroom-express.
