combine configuration from multiple repositories

[shalom938]

We are using config server for many services, we share common configuration for services by calling the files with different file name prefix and then we set multiple application names, for example:

myapp.yml
myapp-amsterdam.yml
myapp-bangkok.yml
kafka-producer.yml
kafka-producer-amsterdam.yml
kafka-producer-bangkok.yml

then in the service bootstrap.yml :

spring.application.name=myapp,kafka-producer
spring.cloud.config.profiles=bangkok

this works fine

now we want a service to also be a cassandra-client, we could do the same but for various reasons we want the cassandra configuration to reside in a separate git repo, we tried by configuring the spring.cloud.config.server.git.repos with different patterns but it didn't work, config server would only load configuration from one git repo. so we actually want to combine configuration from different git repositories. or a repository url could be a list of repositories.

Duplicate of #286?

Overrides is not a good solution for us. this is more a duplicate of #383.

we already rejected #383
