Answer 1

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.

Answer 2

to clarify @barbakini's answer, to define it in applications.yaml use:

spring.data.mongodb.host: mongodb

Coronel

how does this answer differ from the previous Answer? – Fragonard

its explicit, not implicit :) – Coronel

Answer 3

Your mongoDB service is not UP ,

Check the status by following command

sudo service mongodb status

sudo service mongodb start

Hope it should work, there could be several reasons as well , like the configuration you defined in your application for mongodb service is incorrect such as port .

Might be Mongo is not yet installed. – Groundnut

mongodb: unrecognized service – Husbandman

Will never work because you are not searching inside your docker container, but on your host only, and mongodb could be installed (and different one) or not at all. That's why some people get "unrecognized service" or "connection refused" messages. – Jordon

Answer 4

Try to add
network_mode: host
and remove
links: ....
for all services, that want to connect with mongo or eureka or postgresql, inside your docker-compose.yml.
By doing so you will connect to docker localhost.
