1. b and c: There are two labels that are always required. We will need to ensure Interlock forwards the service's requests using com.docker.lb.hosts and com.docker.lb.port. These will have all the required information, but com.docker.lb.network is recommended and required if the service's instances are attached to more than one network. We need to specify which network should be used as an ingress.
2. b: The Interlock solution is based on a main process named interlock, a process for managing external proxy services and configurations, and an interlock-proxy service that will run inside the Docker Enterprise environment if no external load balancer is specified. These three processes run as services within Docker Swarm and they are prefixed with ucp-. ucp-interlock-controller does not exist.
3. d: By default, only the ucp-interlock service will be located by the node's roles. All other components can run anywhere. We will use location constraints to run the ucp-interlock...
