Answer 1

When using docker:dind a container is created and your docker-compose containers get setup within it. It exposes the ports to localhost within the docker:dind container. You cannot access this as localhost from the environment that your code is executing in.

A hostname of docker is setup for you to reference this docker:dind container. You can check by using cat /etc/hosts.

Instead of referencing localhost:9143 you should use docker:9143.
