This question is similar to (but different in the aim): Shared Config(at git) between SPring Boot Services so I will make use of the example the OP wrote there.
In my case I am using Spring Cloud Config Server with the Vault as backend, but for the sake of argument I will describe it as if it were in git. So imagine I have 4 Services: A, B, C and D.
And I have the following configs:
- A-prod.properties
- A-dev.properties
- B-prod.properties
- B-dev.properties
- C-prod.properties
- C-dev.properties
- D-prod.properties
- D-dev.properties
- application-prod.properties
- application-dev.properties
Now according to the docs I will have one of the services, let's say Service C getting his properties from C-(ENV).properties as well as application-(ENV).properties. Similarly the same with the others, i.e. everyone gets their own file and everything on application.properties.
My question is:
Is it possible to have for example a "semi-global" shared properties, e.g. a file that A and C share some config and another that B and D share some config?
An usage example would be DB Connection Credentials, where two services make use of one set of credentials, and the others another one.
I have been trying to find infos about this and doing some tests, but nothing that got me anywhere...
Unfortunately, it's not possible to achieve what you want. The only way to share properties is by using the application.properties(yml) file which is merged to every other configuration file.
