Config with Spring Cloud Config

Question

I would like to ask two questions about the Spring Cloud Config.

1) Is it possible to do an implementation of Spring Cloud Config Server to recover the properties of a base mongodb instead of git?

2) The Spring Cloud Config Client Setup automatically update when you have a change in ownership in Spring Cloud Config Server?

Thanks!!!

Spring Cloud Config Server MongoDB is now available on Github.

To get it up and running all you need to do is add the maven config as below, add @EnableMongoConfigServer to your Spring Boot application configuration and configure desired spring.data.mongodb.* properties.

<dependencies>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-server-mongodb</artifactId>
        <version>0.0.1.BUILD-SNAPSHOT</version>
    </dependency>
</dependencies>

<repositories>
    <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>

Then you can add configuration documents to MongoDB like this:

db.appname.insert({
   "label": "master",
   "profile": "prod",
   "source": {
        "user": {
            "max-connections": 1,
            "timeout-ms": 3600
        }
    }
});

And access them via http://localhost:8080/master/appname-prod.properties to obtain a response like this:

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

UPDATE We have upgraded spring-cloud-config-server-mongodb to use spring-boot 1.5.7 snapshots.

Yes, it is possible, pull requests are welcome
There is no push, but you can use spring's @Scheduled to call RefreshEndpoint.refresh() on an interval basis.

First thanks for the reply, it comes to my two other doubts. ***1)*** How do I cancel the creation of the bean **ConfigServerConfiguration$GitRepositoryConfiguration** that error when I set up, since I will not use it like to cancel. ***2)*** How do I create a custom **EnvironmentRepository** in my mongodb case. – André Justi May 05 '15 at 00:11
See these two links for help: https://github.com/spring-cloud/spring-cloud-config/blob/master/spring-cloud-config-server/src/main/java/org/springframework/cloud/config/server/ConfigServerConfiguration.java#L69-L79 and https://github.com/spring-cloud/spring-cloud-config/blob/master/spring-cloud-config-server/src/main/java/org/springframework/cloud/config/server/SvnKitEnvironmentRepository.java Basically you run config server with a different profile that creates a bean of `EnvironmentRepository` like someone else did for svn. – spencergibb May 05 '15 at 13:53

Not sure about 1. For 2) You have spring-cloud-bus which can provide push notifications to all the clients automatically when you make a change in the config server. http://cloud.spring.io/spring-cloud-config/spring-cloud-config.html

Following are needed: 1. RabbitMQ/ Redis running locally 2. Add this dependency in config server pom xml. Use Brixton.M5 build.

<parent>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-starter-parent</artifactId>
      <!-- <version>Brixton.BUILD-SNAPSHOT</version> -->
      <version>Brixton.M5</version>
      <relativePath /> 
    </parent>
<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-config-monitor</artifactId>
        <scope>test</scope>
    </dependency>
     <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-bus-amqp</artifactId>
    </dependency>

3. Use the bus dependency in addition to the spring-config-client dependencies you might already have:

        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-bus-amqp</artifactId>
        </dependency>

4. [POST]http://localhost:/monitor?path= - this should push notifications to the clients. Alternately you can use a github webhook to post automatically where there is a change in the file.

You can refer to the post here

1. I recommend this git projecto to do that: https://github.com/spring-cloud-incubator/spring-cloud-config-server-mongodb

2. First, after make all your changes, add the @RefreshScope tag to your rest controller if you don't have it, like this:

@RefreshScope
@RestController
class MessageRestController {
   @Value("${message:Hello default}")
    private String message;

    @RequestMapping("/message")
    String getMessage() {
        return this.message;
    }

Next you need send an empty HTTP POST to the client’s refresh endpoint like this:

http://localhost:8080/refresh

note: you can use RESTclient plugin or POSTMAN in your browser to do that.

Finally probe the new message after a few seconds http://localhost:8080/message

note: this example is for client by default configuration...
