Why I have exception opening a socket? How to fix this problem?
You are setting mongodb host in property file as localhost. In a container localhost address itself, but your mongodb is not in that container(car-service) which car-service run in. While you are using docker compose, you can address a container with its name. In your case it is mongodb.
