Spring Cloud Config Client: Fetching config from wrong server

Question

When I run my Spring Cloud Config Client project config-client, I found these error:

Apparently, the config server is wrong. However, the Spring Cloud Config Server is running at localhost:10000/ and application.yml of the project(config-client) is below. Why the spring.cloud.config.uri doesn't work?

application.yml [config-client]

server:
  port: 10001
spring:
  application:
    name: config-client
  cloud:
    config:
      label: master
      profile: dev
      uri: http://localhost:10000

Answer 1

Fur future readers, as answered here, when using Spring Cloud Config Server, we should specify basic bootstrap settings such as : spring.application.name and spring.cloud.config.uri inside bootstrap.yml (or "bootstrap.properties").

Upon startup, Spring Cloud makes an HTTP call to the config server with the name of the application and retrieves back that application's configuration.

That's said, since we're externalizing our settings using Spring Cloud Config Server, any default configurations defined in application.yml (or "application.properties") will be overridden during the bootstrap process upon startup.

IntelliJ Users: add the following override parameter in the run/Debug Configuration:

Name: spring.cloud.config.uri

Value: http://your-server-here/config-server
