Bootstrapping Spring Cloud Config Server MongoDB

Bootstrapping a configuration server with Spring Cloud Config Server MongoDB is just a matter of three steps. Learn what they are and look at a usage example!

Built by the engineers behind Netezza and the technology behind Amazon Redshift, AnzoGraph is a native, Massively Parallel Processing (MPP) distributed Graph OLAP (GOLAP) database that executes queries more than 100x faster than other vendors.  

Spring Cloud Config Server MongoDB enables the seamless integration of the regular Spring Cloud Config Server with MongoDB to manage external properties for applications across all environments.

A Simple Config Server

Bootstrapping a configuration server with Spring Cloud Config Server MongoDB is just a matter of the following three steps.

  1. Configure your pom.xml:

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server-mongodb</artifactId>
            <version>0.0.2.BUILD-SNAPSHOT</version>
        </dependency>
    </dependencies>
    
    <repositories>
        <repository>
            <id>spring-snapshots</id>
            <name>Spring Snapshots</name>
            <url>https://repo.spring.io/libs-snapshot-local</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
        <repository>
            <id>ojo-snapshots</id>
            <name>OJO Snapshots</name>
            <url>https://oss.jfrog.org/artifactory/libs-snapshot</url>
            <snapshots>
                <enabled>true</enabled>
            </snapshots>
        </repository>
    </repositories>
  2. Create a standard Spring Boot application with the EnableMongoConfigServer annotation:

    @SpringBootApplication
    @EnableMongoConfigServer
    public class Application {
    
        public static void main(String[] args) {
            SpringApplication.run(Application.class, args);
        }
    
    }
  3. Configure the application's spring.data.mongodb.* properties in application.yml:

    spring:
      data:
        mongodb:
          uri: mongodb://localhost/config-db

Usage

We can now add configuration documents to MongoDB and access it via the REST API.

  1. Add configuration documents to MongoDB:

    use config-db;
    
    db.gateway.insert({
      "label": "master",
      "profile": "prod",
      "source": {
        "user": {
          "max-connections": 1,
          "timeout-ms": 3600
        }
      }
    });
  2. Access it by invoking  http://localhost:8080/master/gateway-prod.properties:

    user.max-connections: 1.0
    user.timeout-ms: 3600.0

Spring Cloud Config Client-backed components can be configured to automatically load configuration from MongoDB by leveraging Spring Cloud Config Server MongoDB. See here for an example!
