Config Server Sample

A Sample Spring Boot Configuration Server

Build & Run

./gradlew bootRun

Source configuration

This sample project uses the file based storage (Filesystem). Other options exist, namely:

• Git
• Vault
• JDBC
• Composite

The file paths for this sample project can be configured in src/main/resources/application.yml

Query configuration

Spring Boot Config Server support output in a number of formats, regardless of source format. Do get the output in a format of your choice, you simply change the file extension of the requested resource.

curl http://localhost:8888/service-qa.properties
curl http://localhost:8888/service-qa.yaml
curl http://localhost:8888/service-qa.json

Properties inheritance

You can see the way Config Server handles inheritance and overrides when querying

curl http://localhost:8888/service-development.json

The global variable global.settings.some-setting is inherited from the global definition in src/main/resources/service/service.yml

The variables token and shop.location are added in the the service's defintion in the development profile declared in src/main/resources/service/development/service.yml

Querying the service with production or qa profile, you can see that shop.name is overridden as the setting in the given profiles and the global values defined are available as well.
