Spring Cloud Kubernetes Service Catalog Connector

A Spring Cloud Connector for Kubernetes Service Catalog.

Features

• Easily retrieve info for Service Catalog managed services.
• Spring Cloud integration.

What it does behind the scenes is that it retrieves the service bindings of a managed instance and through that it obtains the connection information (which is stored as as a secret).

Usage

To use this connector just follow these steps:

-add the connector to classpath -create an instance of cloud -get the service info from the cloud.

Adding the connector to the classpath

Using maven

For example using maven:

<dependency>
  <groupId>me.snowdrop</groupId>
  <artifactId>servicecatalog-connector</artifactId>
  <version>0.0.1</version>
</dependency>

Create an instance of the cloud

To create an instance of Cloud and retrieve info about a service instance:

Cloud cloud = new CloudFactory().getCloud();
ServiceInfo info = cloud.getServiceInfo(serviceInstanceName);

Here's a full example of a program that prints service info in the console: service info printer.

Integrate with Spring Cloud

Spring cloud already supports connectors and it makes it very easy to consume services supported by the connector. The user just needs to use a ServiceConnectionfactory and create the connections by referencing the service instance by name.

The easiest way to do so, is by extending AbstractCloudConfig.

@Configuration
public class CloudConfig extends AbstractCloudConfig {

    @Bean
    public DataSource dataSource() {
       return this.connectionFactory().service("dh-postgresql-apb", DataSource.class);
    }
}

For a full example check: simple database.
