Hi, Marcel I tried to run containers, but error occurs like the below, ``` $ docker-compose up -d Creating network "dockercitoolstack_prodnetwork" with driver "bridge" Creating volume "dockercitoolstack_nexus-data" with default driver Creating volume "dockercitoolstack_jenkins-data" with default driver Building nexus ERROR: Cannot locate specified Dockerfile: Dockerfile ``` I guess that there is something wrong at your docker-compose.yml. services: nexus: build: ./docker-nexus3 -> ./nexus Could you check it out?
