I try to figure out why the communication between dockerized Spring boot app and mongoDB is not working. First things first:
The whole microservice is running localy perfectly.
I create an application.properties with the profile name docker:
application-docker.properties
server.port=8091
spring.application.name=customer
# ============================================================================================================
# EUREKA
# It's not possible to use localhost in the docker container. Instate use the container name.
# In this case "eureka-server". See the file docker-compose.yml to check the container name.
eureka.client.service-url.defaultZone=http://eureka-server:8761/eureka
eureka.client.fetch-registry=true
eureka.client.register-with-eureka=true
# ============================================================================================================
# ZIPKIN
# It's not possible to use localhost in the docker container. Instate use the container name.
# In this case "zipkin". See the file docker-compose.yml to check the container name.
spring.zipkin.base-url=http://zipkin:9411
# ============================================================================================================
# RABBIT_MQ
# It's not possible to use localhost in the docker container. Instate use the container name.
# In this case "rabbitmq". See the file docker-compose.yml to check the container name.
spring.rabbitmq.addresses=rabbitmq:5672
rabbitmq.exchanges.internal=internal.exchange
rabbitmq.queue.notification=notification.queue

Problem
When I check now the customer log in docker i facet following:

Somewhere I make a mistake. I would be very grateful for a hint.

OK, working solution for me:
application-docker.properties
docker-compose.yml
You’re missing an ‘s’ in
spring.data.mongodb.uriin your config file.
