<p>Spring Cloud provides tools for developers to quickly build some of
|
|
the common patterns in distributed systems (e.g. configuration
|
|
management, service discovery, circuit breakers, intelligent routing,
|
|
micro-proxy, control bus, one-time tokens, global locks, leadership
|
|
election, distributed sessions, cluster state). Coordination of
|
|
distributed systems leads to boiler plate patterns, and using Spring
|
|
Cloud developers can quickly stand up services and applications that
|
|
implement those patterns. They will work well in any distributed
|
|
environment, including the developer’s own laptop, bare metal data
|
|
centres, and managed platforms such as Pivotal Cloudfoundry.</p>

Spring Cloud Config provides server and client-side support for externalized configuration in a distributed system. With the Config Server you have a central place to manage external properties for applications across all environments. The concepts on both client and server map identically to the Spring <code>Environment</code> and <code>PropertySource</code> abstractions, so they fit very well with Spring applications, but can be used with any application running in any language. As an application moves through the deployment pipeline from dev to test and into production you can manage the configuration between those environments and be certain that applications have everything they need to run when they migrate. The default implementation of the server storage backend uses git so it easily supports labelled versions of configuration environments, as well as being accessible to a wide range of tooling for managing the content. It is easy to add alternative implementations and plug them in with Spring configuration.

<p>The server is a Spring Boot application so you can build the jar file

<p>The default strategy for locating property sources is to clone a git

repository (at "spring.platform.config.server.uri") and use it to
|
|
initialize a mini <code>SpringApplication</code>. The mini-application’s
|
|
<code>Environment</code> is used to enumerate property sources and publish them
|
|
via a JSON endpoint. The service has resources in the form:</p>

<pre>/{application}/{profile}[/{label}]</pre>

</div>
|
|
</div>
|
|
<div class="paragraph">
|
|
<p>where the "application" is injected as the "spring.config.name" in the
|
|
<code>SpringApplication</code> (i.e. what is normally "application" in a regular
|
|
Spring Boot app), "profile" is an active profile (or comma-separated
|
|
list of properties), and "label" is an optional git label (defaults to
|
|
"master").</p>

<h3 id="_client_side_usage">Client Side Usage</h3>

<div class="paragraph">
|
|
<p>To use these features in an application, just build it as a Spring
|
|
Boot application that depends on spring-cloud-config-client
|
|
(e.g. see the test cases for the config-client, or the sample app).
|
|
When it runs it will pick up the external configuration from the
|
|
default local config server on port 8888 if it is running. To modify
|
|
the startup behaviour you can change the location of the config server
|
|
using <code>bootstrap.properties</code> (like <code>application.properties</code> but for
|
|
the bootstrap phase of an application context), e.g.</p>

<p>There is a sample application

<a href="https://github.com/spring-cloud/spring-cloud-config/tree/master/spring-cloud-config-sample">here</a>. It
|
|
is a Spring Boot application so you can run it using the usual
|
|
mechanisms (for instance "mvn spring-boot:run"). When it runs it will
|
|
look for the config server on "http://localhost:8888" by default, so

|
you could run the server as well to see it all working together.</p>

</div>
|
|
<div class="paragraph">
|
|
<p>The sample has a test case where the config server is also started in

the same JVM (with a different port), and the test asserts that an

|
environment property from the git configuration repo is present. To
|
|
change the location of the config server just set
|

"spring.platform.config.uri" in "bootstrap.yml" (or via System

|
properties etc.).</p>

</div>
|
|
<div class="paragraph">
|
|
<p>The test case has a <code>main()</code> method that runs the server in the same

|
way (watch the logs for its port), so you can run the whole system in
|
|
one process and play with it (e.g. right click on the main in your IDE
|
|
and run it). The <code>main()</code> method uses <code>target/config</code> for the working
|
|
directory of the git repository, so you can make local changes there

and see them reflected in the running app.</p>

This project provides Netflix OSS integrations for Spring Boot apps through autoconfiguration
|
|
and binding to the Spring Environment and other Spring programming model idioms. With a few
|
|
simple annotations you can quickly enable and configure the common patterns inside your
|
|
application and build large distributed systems with battle-tested Netflix components. The
|
|
patterns provided include Service Discovery (Eureka), Circuit Breaker (Hystrix),
|
|
Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon).
