Introduction to Spring Cloud-config Server

The server provides resource-based HTTP for external configuration (name-value pairs or equivalent yaml content). the server can be @EnableConfigServer easily embedded in the spring boot application using annotations. So this application is a configuration server:

Configserver.java

@SpringBootApplication@EnableConfigServerpublic class ConfigServer {  public static void main(String[] args) {    SpringApplication.run(ConfigServer.class, args);  }}

like all spring boot applications running on the default port 8080, you can switch them to regular port 8888 in a variety of ways. The simplest is also to set a default configuration library, which is done by starting it spring.config.name=configserver (there is one in the Config Server jar configserver.yml ). the other is to use your own application.properties , for example

application.properties

server.port: 8888spring.cloud.config.server.git.uri: file://${user.home}/config-repo

${user.home}/config-repoThis is the Git repository that contains Yaml and properties files.

Attention

In Windows, if the file URL is an absolute drive prefix, for example file:///${user.home}/config-repo , additional "/" is required.

Tip	Here's how to create a git repository in the example above: $ cd $HOME$ mkdir config-repo$ cd config-repo$ git init .$ echo info.foo: bar > application.properties$ git add -A .$ git commit -m "Add application.properties"

Warning

use the local file system for git repositories for testing only. Use the server to host the configuration library in a production environment.

Warning

If you keep only text files, the initial cloning of the configuration library will be quick and efficient.  If you start to store binaries, especially large files, you may experience a delay in the first configuration request and/or out-of-memory error in the server.
