What Will I Learn?
  • The students will learn how to use to host a centralized configuration repository that can be used for Spring cloud and/or MicroServices instances.
  • The Students will learn how to use Spring RestTemplate to pull Spring Configuration from a centralized Spring Cloud Config Server.
  • Students will learn how configuration is stored and managed in Cloud Config
  • Students will learn how branching and tagging of configuration can provide total control over complex configuration requirements
  • Students will learn how to secure the Spring Cloud Config endpoints with BASIC Authentication.
  • Students will create a Client application that connects to a Config Server using BASIC Authentication.
View Curriculum
  • The student should be familiar with the SpringFramework, inversion of control (IoC) @Profile's and the Spring configuration lifecycle.
  • The student should be familiar with Spring boot.
  • The student should be familiar with GIT, versioning files, and potentially branching and labeling.
  • The student should have some exposure to Maven and/or Gradle build system tool.

This course will lead intermediate to advanced SpringFramework and Spring Boot developers in creating a centralized Cloud Configuration server for use in cloud environments and MicroService architectures.

The course starts by creating a centralized Spring Cloud Config server. Students will learn how this can be used with or without a cloud oriented system like AWS. This technique can give great flexibility and manageability to any Spring-based deployment.

Students will create Spring Boot projects based mostly on Maven, but will also learn how to create the same projects using Gradle.

Then students will create a local GIT repository and pushing configuration files the students have created.

Then students will create remote Spring Boot clients to pull configuration from the Central config server, detailing out the various configuration that each remote application retrieve.

The students will then cover additional topics such as GIT TAG's and BRANCH's, and how applications can pull from them.

Students will also learn techniques for dynamically changing version of configuration to be pulled from a Spring Cloud Config server, for applications like parallel Microservice deployments.

Spring Cloud Config Server features:

  • HTTP, resource-based API for external configuration (name-value pairs, or equivalent YAML content)
  • Encrypt and decrypt property values (symmetric or asymmetric)
  • Embeddable easily in a Spring Boot application using @EnableConfigServer
  • Enable BASIC Authentication for configuration access

Config Client features (for Spring applications):

  • Bind to the Config Server and initialize Spring Environment with remote property sources
  • Bind directly to complex Objects using @ConfigurationProperties with remote property source
  • Enable BASIC Authentication for configuration access


Who is the target audience?
  • Spring Framework and/or Spring Boot developers that want to learn about distributed Spring configuration management with Spring Cloud Config.

Overview of what the Spring IO platform

Spring IO platform

Spring IO is a cohesive, versioned platform for building modern applications. It is a modular, enterprise-grade distribution that delivers a curated set of dependencies while keeping developers in full control of deploying only the parts they need. Spring IO is 100% open source, lean, and modular.

Preview 08:22

Spring Boot makes it easy to create stand-alone, production-grade Spring based Applications that you can "just run". We take an opinionated view of the Spring platform and third-party libraries so you can get started with minimum fuss. Most Spring Boot applications need very little Spring configuration.


  • Create stand-alone Spring applications
  • Embed Tomcat, Jetty or Undertow directly (no need to deploy WAR files)
  • Provide opinionated 'starter' POMs to simplify your Maven configuration
  • Provide production-ready features such as metrics, health checks and externalized configuration
  • Absolutely no code generation and no requirement for XML configuration

The "https://docs.spring.io/spring-boot/docs/current-SNAPSHOT/reference/htmlsingle" reference guide includes detailed descriptions of all the features, plus an extensive howto for common use cases.

Spring Cloud

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 AWS, Google Cloud and Cloud Foundry.

Setup Spring Cloud Config Server
6 Lectures 17:51

Create a Maven and Gradle based Spring Boot application from the Spring Boot INITIALIZR web application.

Preview 06:27

The initial startup of the Spring Cloud config Server with the Maven wrapper, then the Gradle Wrapper, then testing the health of the server with the Actuator /health endpoint.

Initial Maven then Gradle startup of Config Server

Import the Gradle project into a new Intellij IDEA project.

Import Server project into IDEA

Students will perform some basic configuration on this Spring Boot application to ensure the server is ready to serve configuration requests once we have configuration to serve.

Configure Config Server

Setup GIT Configuration Repository
9 Lectures 54:37

Create an empty local git repository

Preview 02:49

Create a properties file on Master branch and create TAG

LAB: Spring Cloud Config Server

Create a YAML file, adding it to the repo and committing it to the Master branch.

Then create a GIT TAG for this specific commit. (v.1.1)

Then we will review pulling the configuration from the server.

Will talk about GIT Lifecycles related to pulling configuration.

We then pull configuration for v.1.0, and then v.1.1

Create YAML file on Master create TAG

Create a properties and YAML file for "dev" profile, adding them to the repo and committing it to the Master branch.

Then create a GIT TAG for this specific commit. (v.2.0)

Then we will review pulling the configuration from the server.

We then pull configuration for TAG v.2.0, then for "dev" profile.

Then we show how attempting to pull TAG v.2.0 with an invalid profile name.

Create Properties and YAML file on Master, w/Profile, create TAG

Modify properties and YAML files for "default" and "dev" profile, committing it to the HOTFIX branch only.

Then create a GIT TAG for this specific commit. (v.3.0)

We will review pulling default configuration from the server, and then for "dev" profile.

We then pull configuration for branch HOTFIX and then for "dev" profile.

We then pull configuration for TAG v.3.0, then for "default" profile.

We then pull configuration for TAG v.3.0, then for "dev" profile.

Create Properties and YAML file on HOTFIX branch, w/Profile, create TAG

Pull LABEL and Profile configuration from Config Server

Spring Cloud Config Clients
12 Lectures 56:33

In this lecture, we will go over some basic configuration of the Client application that will be pulling configuration from our central server.

We will discuss the correlation of this local configuration to the reference of centralized configuration.

We then will discuss how to set the Profile, and TAG / LABEL for the client application.

Configure Spring Cloud Microservices Client Application

Create Spring RestController to expose configuration of this Service Endpoint

Verify Default Profile Service Endpoint Properties

LAB: Spring Cloud Config Client

Create custom @ConfigurationProperties Object to encapsulate complex properties, and verify we can pull complex Configuration properties from the Config Server.
