Centralized Configuration with Spring Cloud Config

Centralized configuration is a crucial aspect of microservices architectures. It lets you manage the configuration of all your services from a single central point, which simplifies maintenance and ensures consistency.

1. Setting Up the Config Server

1.1 Creating the Config Server Project

curl https://start.spring.io/starter.tgz \
    -d dependencies=cloud-config-server \
    -d groupId=com.example \
    -d artifactId=config-server \
    -d name=config-server \
    -d description=Config%20Server%20for%20Microservices \
    -d packageName=com.example.config \
    -d packaging=jar \
    -d javaVersion=17 \
    -d type=maven-project \
    | tar -xzvf -

1.2 Server Configuration

# application.yml
server:
  port: 8888

spring:
  application:
    name: config-server
  cloud:
    config:
      server:
        git:
          uri: https://github.com/your-org/config-repo
          default-label: main
          search-paths: 
            - config/*
