Dockerfile

RUN mkdir -p /usr/src/app/etc
COPY etc/settings.yml /usr/src/app/etc
COPY target/dwaxis.jar /usr/src/app
WORKDIR /usr/src/app

The apps are running I can cx exec $CONTAINER_ID bash them, then curl the local 80 port and in logs I see correct requests.

I can't access the apps from the host, as they have no port mapping (mapping and ip checked via docker inspect). I guess it's intended so that only local load balancer has access. However the load balancer is either not running or the access is broken.

Some more context:
