I have a set of services that use spring-cloud, connect to a config server, and register to a eureka server.
I created a docker-compose.yml document in order to pull up all the containers in a simple way.
so far so good
There was a problem: the configuration server was not available when the other services were brought up.
So I added spring-retry to make several retries. And it worked fine and i want to keep it.
config:
spring.cloud.config.fail-fast=true
spring.cloud.config.retry.initial-interval=4500
spring.cloud.config.retry.max-attempts=12
spring.cloud.config.retry.max-interval=9000
spring.cloud.config.retry.multiplier=1.9
The problem now is that when building the .jar with "mvn package" the tests fail, since it retries to connect to the services and cannot find them:

I tried to skip the tests with "mvn package -Dmaven.test.skip" and everything works fine. But I don't think it's a good practice.
The question is: How can you use spring-retry and pass the tests?
