Start the project

Build config-service project with maven. Use JDK 11, which is LTS. mvn clean install
Run config-service docker-compose up.
Use POSTMAN, curl or another HTTP client. Note, Postman can sent default headers, including Accept. Please, make sure, you overwrite it then.

Results:

1) Works service1, which has field value empty.

HTTP GET http://localhost:8888/service1/dev

2) Works with Accept header

Accept:application/vnd.spring-cloud.config-server.v2+json HTTP GET http://localhost:8888/service1/dev

3) Works with service2; field has value empty array.

HTTP GET http://localhost:8888/service2/dev

4) Fails with service 2, with Accept header

Accept:application/vnd.spring-cloud.config-server.v2+json HTTP GET http://localhost:8888/service2/dev Response

How to debug

1) Create remote debug configuration in your IDE.

2) Add `JAVA_OPTIONS` to the service you want to debug.

- "JAVA_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005"

3) Open ports.

ports:
  - 5005:5005

4) Total example.

  config-service:
    build:
      context: "./config-service"
      dockerfile: Dockerfile
    container_name: config-service
    volumes:
      - "./configuration:/configuration:ro"

      - "GIT_REPOSITORY_URI=https://github.com/yan-khonski-it/spring-cloud-config-demo"
      
      # Debug the service
      - "JAVA_OPTIONS=-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005"
